Alternating pressure mattress: Overview, Uses and Top Manufacturer Company

Posted on February 26, 2026 | by drthomas

Introduction

An Alternating pressure mattress is a pressure-redistribution support surface used in hospitals, long-term care facilities, and home-care programs to help manage and reduce risk factors associated with pressure injuries (also called pressure ulcers). It is considered a piece of hospital equipment and a clinical device because it changes how pressure is distributed at the patient–mattress interface over time, rather than relying only on a static foam surface.

Pressure injuries are generally understood as localized damage to skin and/or underlying tissue, usually over a bony prominence, that can also be related to pressure from medical devices. Clinically, teams may describe injuries by stage (or category) such as non-blanchable erythema, partial-thickness skin loss, full-thickness skin loss, deep tissue injury, or unstageable wounds when tissue depth cannot be determined. Even when “only redness” is present, it may still represent early tissue compromise and can escalate quickly in patients with poor perfusion, edema, or fragile skin.

Why this matters: pressure injuries are closely linked to immobility, illness severity, device-related pressure, moisture, friction, and shear. They affect patient comfort, length of stay, nursing workload, and cost of care. A properly selected and correctly operated Alternating pressure mattress can be one component of a wider prevention and care bundle that includes repositioning, skin assessment, nutrition assessment, and moisture management—always guided by local protocols and clinical judgment.

From a systems perspective, pressure injury prevention is often a quality and safety priority because events are measurable, potentially preventable, and associated with downstream complications (infection risk, pain, deconditioning, delayed rehabilitation, and higher resource use). Support surface selection therefore has implications beyond the bedside: it affects staffing workload, equipment fleet size, cleaning turnaround, and escalation pathways for high-risk patients.

This article is written for both learners and operational leaders. Medical students and residents will learn what the device is, how it functions, how it is commonly used on the ward and in critical care, and what “good practice” looks like. Administrators, biomedical engineers, and procurement teams will find practical points on setup, safety checks, cleaning, troubleshooting, and market considerations—without brand-specific claims.

A useful framing is to think of support surfaces as reactive (they redistribute pressure primarily by “giving” under load without powered cycling) versus active (they actively change pressure distribution using a pump and programmed patterns). Alternating pressure mattresses fall in the active category, and that brings both advantages (reduced duration of sustained pressure) and operational considerations (power dependence, alarms, maintenance, and staff training).

What is Alternating pressure mattress and why do we use it?

An Alternating pressure mattress is a dynamic air support surface that uses a powered pump to cyclically inflate and deflate groups of air cells inside a mattress. The aim is to periodically shift load from one set of body contact points to another, reducing the duration of sustained pressure on any single area.

Purpose (plain language)

When a patient lies still for long periods, certain body areas (often bony prominences like the sacrum, heels, hips, and shoulders) experience higher, sustained pressure. Over time, sustained pressure—especially when combined with shear, moisture, and poor perfusion—can contribute to skin and tissue breakdown. An Alternating pressure mattress is designed to redistribute pressure over time by changing which cells are firm versus soft during a repeating cycle.

It can be helpful to distinguish two related goals:

Lowering peak pressure at vulnerable points (for example by allowing the body to “immerse” into the surface)
Reducing time under pressure by periodically changing which areas carry more load (the “alternating” component)

Both goals may matter, and the relative importance can vary by patient. For example, a patient with severe edema or poor perfusion may be more sensitive to even moderate sustained pressure, while a patient with agitation may be more affected by friction and shear during frequent repositioning.

Where it is commonly used

You will see an Alternating pressure mattress in many clinical settings, including:

Intensive care units (ICU), especially for sedated, ventilated, or vasopressor-dependent patients who are difficult to reposition frequently
Medical and surgical wards for patients with limited mobility, high acuity, or elevated pressure injury risk
Step-down units, rehabilitation wards, and long-stay areas
Long-term care and complex home-care programs (availability and models vary by region)
Post-operative recovery when immobility is expected (use depends on local protocol and surgical needs)

In practice, alternating surfaces may also appear in:

High-dependency observation areas (e.g., monitored bays) where frequent turning may be limited by staffing ratios
Palliative care when comfort is a dominant goal and the patient is spending prolonged time in bed (selection should still be individualized)
Neurology and neurosurgery units where impaired sensation or reduced consciousness elevates risk, while positioning restrictions may exist

Benefits in patient care and workflow (general)

Potential operational and care benefits include:

Pressure redistribution over time without relying solely on manual repositioning (not a replacement for repositioning unless local policy explicitly allows)
Standardized support surface for high-risk cohorts, which can simplify bed management and escalation pathways
Comfort tuning (within limits) using weight/firmness settings on the pump, which may improve tolerance for some patients
Reduced “bottoming out” risk compared with some basic overlays, when the device is correctly sized, inflated, and maintained (varies by model)

Additional practical benefits that teams often notice include:

Consistency across shifts: when staff are familiar with a surface, it can reduce variability in how “high-risk” patients are supported.
Procedure facilitation: “max inflate/firm” functions (when available) can make linen changes and some bedside procedures easier and potentially reduce shear during handling.
Escalation clarity: many facilities use a support-surface ladder (foam → higher-spec foam → dynamic alternating) that aligns with risk scores and wound care recommendations.

It is also fair to acknowledge trade-offs:

Dynamic surfaces may feel less stable for some patients, affecting confidence during mobilization.
Pumps add noise, require electricity, and introduce alarm management and maintenance tasks.
Some patients perceive the alternating pattern as “moving” or “vibrating,” especially at night.

Mechanism of action (how it functions)

Most Alternating pressure mattress systems include:

A mattress body with multiple interconnected air cells
A pump/control unit that provides air flow and regulates pressure
Air hoses/connectors linking pump to mattress
A cover designed to be fluid-resistant and cleanable (features vary by manufacturer)

The pump alternates inflation between two (or more) groups of air cells—often described conceptually as “A cells” and “B cells.” While one group is more inflated and supportive, the other group is less inflated, reducing pressure under the corresponding body zones. After a set cycle time, the groups switch. Some systems also offer modes like “static,” “max inflate,” or “seat/firm” (names and behaviors vary by manufacturer).

Many design details affect how this feels and performs in real use, for example:

Alternation pattern: some mattresses alternate every other cell (often described as 1-in-2) while others use different patterns (such as 1-in-3). Patterns influence stability and pressure redistribution.
Cycle time: some pumps allow adjustment (shorter cycles may feel “busier,” longer cycles may be less noticeable). Others have fixed cycles.
Cell design: some systems use “cell-in-cell” or similar constructions intended to provide a safety layer if one cell loses pressure (model-dependent).
Zoned therapy: heel, sacral, or shoulder zones may inflate differently to target high-risk areas, sometimes with specific “heel relief” design features.
Microclimate features: some surfaces include airflow through or around the cover (often described as low-air-loss features) to help manage heat and moisture, though this is not universal and depends on the mattress type.

Understanding “pressure redistribution” beyond air movement

Alternation is only one part of support-surface performance. Clinically relevant concepts often used by wound-care teams include:

Immersion: how far the body sinks into the surface, increasing contact area and reducing peak pressure.
Envelopment: how well the surface conforms around body contours, supporting the body without creating localized high-pressure ridges.
Shear management: while no mattress can eliminate shear caused by sliding, some designs reduce shear forces by allowing controlled movement within the surface.

Thinking in these terms helps explain why two “alternating” systems can feel very different for a patient and may require different settings and handling practices.

How medical students typically encounter this device

In training, learners most often meet the Alternating pressure mattress through:

Nursing handovers and bedside rounding: “This patient is on an alternating surface.”
Pressure injury prevention bundles: risk assessment tools, turning schedules, heel offloading, and device-related pressure checks
Ward operations: bed moves, isolation rooms, cleaning delays, and equipment shortages
Clinical documentation: support surface selection, skin assessment findings, and comfort/positioning notes
A useful learning habit is to ask: What is the goal of this surface for this patient, and how are we verifying it is working?

Learners also often see how these devices intersect with day-to-day logistics:

A patient may return from imaging and the pump is unplugged or left in the wrong mode.
A confused patient may accidentally pull tubing, triggering low-pressure alarms.
Therapy sessions may be affected because the patient feels “bouncy,” requiring coordination (for example, temporarily switching to a stable mode per policy during transfers).

When should I use Alternating pressure mattress (and when should I not)?

Selection of an Alternating pressure mattress should follow facility policy, local clinical guidelines, and an individualized assessment of risk and tolerance. The points below are general and may vary by manufacturer and local protocol.

Appropriate use cases (common examples)

An Alternating pressure mattress is often considered when a patient:

Has limited ability to reposition independently (e.g., severe weakness, sedation, altered consciousness)
Has elevated risk of pressure injury based on a facility-approved risk assessment method
Has an existing pressure injury where a higher-specification support surface is part of the care plan
Is expected to remain bedbound for prolonged periods due to illness severity or treatment plan
Has care needs that make frequent manual repositioning difficult or unsafe (while still aiming to minimize pressure, shear, and moisture)

Risk assessment in many facilities is supported by tools such as Braden, Norton, or Waterlow-type scales (names and use vary by region). These tools can help standardize screening, but they are not perfect predictors; clinical judgment is still essential. A patient may score “moderate risk” yet have high-risk features such as vasopressor use, severe edema, poor nutritional intake, diabetic neuropathy, or device-related pressure risks.

In practice, clinicians often consider escalation to an alternating surface when there is a combination of:

High risk + limited repositioning ability, or
Existing tissue damage + ongoing exposure to risk factors, or
System constraints (e.g., limited staff capacity to turn as frequently as planned) where a dynamic surface can provide additional protection while the team addresses staffing and workflow.

Situations where it may not be suitable (general considerations)

An Alternating pressure mattress may be less suitable when:

The care plan requires a highly stable, non-moving surface for a specific clinical reason (e.g., certain immobilization requirements)—decision should be clinician-led
The patient cannot tolerate motion or perceives the alternating cycle as distressing, despite adjustments and reassurance
Safe transfers are compromised because the surface is too unstable for a given patient’s mobility level, staffing pattern, or equipment (e.g., high fall risk during edge-of-bed activities)
The mattress is incompatible with the bed frame or clinical environment (weight limits, dimensions, side-rail configuration, or power supply constraints—varies by manufacturer)
Reliable cleaning/turnaround cannot be assured (infection prevention risk may outweigh benefits in some circumstances)

Additional “less suitable” scenarios sometimes encountered include:

Patients needing very precise positioning where small surface shifts could matter (for example, certain post-flap or graft positioning plans, depending on surgical guidance).
Patients with severe motion sensitivity (nausea, vertigo, or anxiety) where the dynamic cycling worsens symptoms.
Situations where staff require frequent standing transfers at the bedside and the dynamic surface increases instability risk; in these cases, teams may use an alternating surface when supine but switch to a stable mode temporarily for mobilization per policy.

Safety cautions and contraindications (non-exhaustive, general)

Do not assume an Alternating pressure mattress replaces repositioning; follow local turning and skin inspection protocols.
Ensure the device is correctly sized for the bed and patient; mismatched sizes can increase entrapment and fall risks.
Avoid adding thick pads or multiple layers that can block the alternating effect and interfere with airflow or alarms (unless specifically permitted by facility policy and manufacturer guidance).
Use particular caution with medical devices that contact skin (oxygen tubing, catheters, casts, drains, cervical collars), because pressure injury risk can shift from bony prominences to device contact points.

It is also important to consider:

Bariatric and very low-weight patients: both ends of the weight spectrum can be challenging. Very high weights may exceed design limits or require bariatric-rated systems; very low weights may need careful adjustment to avoid “hard” feel if pressure is set too high.
Cognitive status and agitation: patients who pull at equipment may be more likely to disconnect hoses or turn off pumps. Mitigation may involve tubing management, education, and close checks.
Electrical safety: because pumps are powered equipment, facilities typically expect safe power practices (appropriate outlets, no damaged cords, and adherence to local electrical safety standards).

Emphasize clinical judgment and supervision

For students and trainees: device choice is usually made by the primary team, wound care specialists, or nursing leadership, with input from therapy and biomedical engineering when needed. If you are unsure whether an Alternating pressure mattress is appropriate, escalate to a supervising clinician and follow facility pathways.

A practical question to ask on rounds is: Are we using this surface for prevention, treatment, or both—and what is the reassessment plan? Support surfaces should be revisited as the patient improves, mobilizes, transfers to a chair more, or conversely deteriorates and becomes less tolerant of turning.

What do I need before starting?

Starting an Alternating pressure mattress safely is as much about systems (policies, maintenance, cleaning, training) as it is about the pump and mattress.

Required setup, environment, and accessories

Common prerequisites include:

A compatible bed frame with appropriate mattress platform and side-rail configuration
A functional Alternating pressure mattress and matching pump unit (model pairing varies by manufacturer)
Air hoses and secure connectors without visible damage
A reliable power outlet and a plan for power interruptions (unit/ward procedures vary)
Any manufacturer-specified accessories (for example, transport caps, spare filters, or protective covers—varies by manufacturer)

Operationally, also ensure:

Adequate space for the pump to be mounted or placed safely (away from water sources and trip hazards)
Tubing routed to avoid kinks, crushing, and entanglement in bed wheels or lift equipment

Depending on your environment, additional practical needs may include:

A backup surface plan (for example, a high-specification foam mattress available on the unit) in case of pump failure or power outage.
Extension management policies: many facilities discourage or tightly control extension cords because of trip and electrical risks. If an extension is used, it should be facility-approved and appropriately rated.
Equipment tracking processes (equipment library, tag system, or electronic tracking), because dynamic mattresses are commonly moved between rooms and units.

Training and competency expectations

Because this is active medical equipment, many facilities require documented competency for nursing staff and support staff. Training typically covers:

Indication and escalation pathways (who approves an Alternating pressure mattress)
Basic modes, alarms, and safe response behaviors (including not ignoring persistent alarms)
Patient safety risks (falls, entrapment, line dislodgement)
Cleaning workflows and “clean/dirty” segregation
Documentation expectations (surface type, settings, checks)

In higher-acuity areas, competency may also include:

Understanding the CPR/rapid deflation feature if present and how it fits into local resuscitation procedures.
Managing transport (whether the pump stays connected, whether the mattress retains pressure for a period when unplugged, and how to avoid accidental deflation).
Recognizing when the mattress is contributing to positioning challenges, such as sliding down in bed at higher head-of-bed angles.

Pre-use checks and documentation (practical)

Before placing a patient on the surface, check:

Asset label/service status (e.g., maintenance sticker), if used in your facility
Mattress cover integrity: no tears, compromised seams, or fluid ingress
Hoses and connectors: secure fit, no cracking, no obvious leaks
Pump exterior: intact casing, readable labels, responsive controls
Alarm function basics (as appropriate to the model and local policy)

Additional checks that are often helpful in real-world workflows:

Confirm the cover is properly zipped/secured (where applicable), since open seams can permit fluid ingress.
Check that pump air intake/exhaust vents are not blocked by blankets, wall hangings, or bed accessories.
If the model uses filters, confirm the filter housing is intact and the filter is not obviously saturated or missing (filter service is typically a preventive-maintenance activity, but visual checks help).
Listen for unusual pump noise or vibration that might suggest mechanical wear.

Document as required by your facility, commonly including:

Surface type (Alternating pressure mattress) and model identifier (if required)
Initial settings/mode used and rationale (e.g., comfort/weight setting)
A baseline skin check and plan for reassessment

Operational prerequisites (commissioning, maintenance readiness, policies)

For administrators and engineering teams, readiness usually includes:

Commissioning of new devices: acceptance checks, safety testing as required locally, and asset registration
Preventive maintenance scheduling (frequency varies by manufacturer and local risk policy)
Spare parts and consumables planning (filters, hoses, covers, connectors—varies by manufacturer)
Defined decontamination and turnaround workflows with infection prevention input
Clear rental vs. owned pathways to manage surge demand (common in some health systems)

Many organizations also formalize:

End-of-life criteria (e.g., repeated cover failure, inability to hold pressure, or pump repair costs exceeding replacement thresholds).
Fleet standardization plans to reduce training variation and simplify parts inventories.
Education refresh cycles for staff, because infrequently used features (like transport caps or CPR valves) can be forgotten.

Roles and responsibilities (who does what)

A practical division of responsibilities is:

Clinicians/nursing teams: assess need, select mode per protocol, position patient, monitor comfort/skin, respond to alarms, document use.
Biomedical engineering/clinical engineering: verify electrical/mechanical safety, manage repairs, perform preventive maintenance, maintain service records, advise on compatibility.
Procurement/value analysis: evaluate total cost of ownership (device, accessories, service), contract terms, training support, cleaning compatibility, and availability of local service.
Infection prevention/environmental services: approve cleaning agents, workflow, and auditing approach; advise on isolation-room processes.

In some hospitals, an equipment services or central equipment library team also plays a key role by managing delivery/pick-up, verifying “clean” status, and coordinating repairs. Where these teams exist, clear handoffs (including “last cleaned” labeling and fault tagging) can prevent delays and unsafe device reuse.

How do I use it correctly (basic operation)?

Exact steps vary by model, but the workflow below reflects common, broadly applicable practice for an Alternating pressure mattress. Always follow local policy and the manufacturer’s IFU (Instructions for Use).

Step-by-step workflow (commonly universal elements)

Confirm the indication and that an Alternating pressure mattress is the intended surface per care plan.
Verify sizing and compatibility with the bed frame and patient needs (including side rails and transfer plans).
Prepare the bed: set brakes, clear clutter, and ensure a safe working height for staff.
If it is a replacement system, remove the existing mattress per facility policy and safe manual handling procedures.
Place the Alternating pressure mattress on the bed base, oriented correctly (head/foot markings vary by manufacturer).
Secure the mattress using straps or anchors if provided/required.
Connect air hoses firmly to the pump and mattress ports; confirm no kinks or crushing points.
Mount or place the pump in a stable position with adequate ventilation (location guidance varies by manufacturer).
Connect to power and switch the pump on; allow time for full inflation before transferring the patient (inflation behavior varies by model).
Transfer the patient safely using appropriate handling equipment (slides, hoists) and staffing.
Select settings/mode appropriate to the patient (commonly a weight/firmness setting and an alternating mode).
Confirm adequate support (many teams perform a “bottoming out” check per local practice).
Set bed safety measures: bed low, rails per policy, call bell accessible, tubing managed.
Document the surface, mode, and initial checks.
Reassess regularly: comfort, skin, alarms, and whether the surface still matches the clinical plan.

A few practical details often make the difference between “installed” and “working as intended”:

Give the mattress time to fully inflate and stabilize before finalizing firmness settings. If settings are adjusted during early inflation, the surface may feel inconsistent.
Ensure the patient is centered on the mattress. If the patient is positioned too high/low or shifted laterally, high-risk areas (like heels) may sit on zones not designed for them, or side-rail gaps may increase.
If the bed is articulated (head-of-bed elevated), consider using features like knee gatch (if present) to reduce sliding and shear, and reassess whether the patient is “migrating” down the bed over time.

Typical settings and what they generally mean

Names differ across brands, but common control concepts include:

Weight/firmness setting: adjusts internal pressure to match patient mass and comfort (incorrect settings can increase risk of bottoming out or excessive firmness).
Alternation cycle: controls how the inflation pattern shifts over time (cycle time may be adjustable or fixed; varies by manufacturer).
Static mode: holds pressure steady (often used temporarily for procedures, transfers, or patient intolerance—use should follow local guidance).
Max inflate/firm mode: temporarily increases firmness to facilitate repositioning, linen changes, or transfers (duration and behavior vary).
Alarm mute/silence: temporarily silences alarms; good practice is to fix the underlying issue rather than relying on silencing.

Where adjustable, cycle times are often set in minutes and may be chosen to balance therapy goals and tolerance. A slower cycle may be less noticeable and more sleep-friendly, while faster cycling may feel more active. Facilities sometimes standardize default settings to reduce variability, then allow individualized adjustments for comfort and clinical needs.

What does a “bottoming out” check usually mean?

Local practice varies, but the intent is the same: confirm the patient’s bony prominences are not so close to the bed base that the surface cannot provide meaningful pressure redistribution.

Common bedside approaches include:

With the patient lying supine, slide a hand (often palm up) under a high-risk area such as the sacrum while the other hand checks the mattress thickness above the bed base. If you can easily feel the firm bed deck under the patient, support may be inadequate.
Check in more than one position (for example, with head-of-bed elevated vs flat), because articulation can change how weight is distributed.

If bottoming out is suspected, typical next steps are to reassess weight/firmness settings, ensure the pump is in the intended mode, remove unapproved overlays, and escalate if the surface still cannot support the patient.

Operational tips that translate across models

Use minimal linen layers consistent with comfort and infection prevention to preserve surface function.
Keep heels and other vulnerable areas in mind; a dynamic mattress does not automatically offload all high-risk points.
Plan for procedures and transfers: some teams switch modes temporarily to improve stability, then restore alternating therapy.

Additional practical habits include:

After any major intervention (linen change, transfer, imaging, bedside procedure), do a quick “three-point check”: pump on + correct mode + no alarms.
Avoid placing heavy objects (warming devices, large equipment bags) on the mattress for prolonged periods, as they can distort cell function and create unintended pressure points.
During chair positioning or “dangling” at the bedside, reassess whether a seat/firm function is appropriate per policy to improve stability, and return to therapy mode afterward.

How do I keep the patient safe?

Patient safety with an Alternating pressure mattress includes mechanical safety, skin safety, mobility safety, and alarm safety. It also includes team behaviors—handovers, documentation, and escalation.

Core safety practices at the bedside

Falls and mobility: dynamic surfaces can feel less stable. Follow facility fall-prevention measures, keep the bed at the lowest safe height, and reassess mobility plans.
Entrapment and side rails: ensure mattress size matches the bed and rails, and that gaps are minimized according to local bed safety practices.
Lines and tubes: route and secure oxygen tubing, catheters, drains, and monitoring leads to reduce snag risk during alternation and repositioning.
Heat and moisture: manage microclimate with appropriate linens, moisture control, and timely hygiene; mattress features vary by manufacturer.
Repositioning: continue scheduled turns and skin checks unless local policy specifies otherwise; an Alternating pressure mattress is typically one layer of protection, not the whole plan.

Additional safety considerations often relevant in acute care:

Shear management with bed elevation: raising the head of the bed can increase shear as the patient slides. Use positioning aids and bed features (like knee break) per local policy, and reassess sacral skin frequently.
Delirium and device interference: confused patients may disconnect hoses or power off the pump. Mitigation includes visible checks, clear tubing routes, and frequent rounding.
Noise and sleep: pump noise and cycling sensation may affect rest. Small changes—like ensuring the pump is mounted securely, vents are unobstructed, and cycle settings (if adjustable) are chosen thoughtfully—can improve tolerance.

Monitoring and safety checks (practical cadence)

Common monitoring elements include:

A skin check aligned to your facility’s pressure injury prevention protocol
A check that the pump is powered on, in the intended mode, and free of persistent alarms
A quick look for hose disconnections, kinks, or mattress cover damage
Patient-reported comfort, especially if the patient is awake and can describe discomfort or dizziness

Many units build these checks into routine workflows:

At the start of each shift (or during safety rounds), verify the surface status and document as required.
After any bed move, room change, or transport, immediately reconfirm settings and alarms.
If the patient’s condition changes (new vasopressors, fever with sweating, new diarrhea/incontinence, new edema), reconsider whether the current surface and microclimate strategy still fit.

Alarm handling and human factors

Alarm management is a frequent failure point. Practical principles:

Treat alarms as actionable signals, not background noise.
Avoid “set and forget”: mode and settings can be changed accidentally during cleaning, bed moves, or linen changes.
During handover, explicitly communicate: “Patient is on an Alternating pressure mattress, mode X, any alarms/issues, and last skin check.”

In well-functioning systems, alarm handling is supported by:

Clear ownership (who responds first, and when to escalate)
Access to quick reference guides (often unit-made summaries aligned with IFU)
Reliable availability of spare hoses or connectors so minor issues can be fixed without prolonged downtime

CPR and emergency considerations (if the mattress has a rapid deflation feature)

Some alternating pressure mattresses include a CPR/rapid deflation function intended to quickly deflate the surface to provide a firmer platform during resuscitation or urgent procedures. How and when to use this should be guided by your facility’s resuscitation policy and the device IFU.

Operationally, teams should know:

Where the CPR control/valve is located
Whether the pump must be restarted or reset after deflation
How long reinflation typically takes and how to protect the patient during that interval

Risk controls beyond the bedside

Operational leaders can strengthen safety by:

Standardizing device models where feasible to reduce training burden (balanced against procurement realities)
Ensuring clear labeling: asset ID, “cleaned” status, and service dates
Promoting a just culture approach to incident reporting for device issues and near misses

Always follow manufacturer guidance and facility protocol, and escalate uncertainty early.

How do I interpret the output?

Unlike monitors that provide physiologic numbers, an Alternating pressure mattress mainly provides device status outputs. Correct interpretation is about confirming the surface is functioning as intended and that it fits the clinical goal.

Common output types

Depending on the model, you may see:

Indicator lights for power, normal operation, and alarms
A digital display showing mode (alternating/static/max inflate), a firmness/weight level, and possibly cycle status
Alarm indicators such as low pressure, hose disconnect, power failure, or service required (terminology varies by manufacturer)
Audible alarms with silence/mute buttons and reset behavior

Some models may also provide:

A lock function to prevent accidental setting changes
A visible or coded indicator of maintenance/service needs (hours of operation, filter reminder, or fault codes)
Automatic adjustment behaviors (the pump may “search” for an optimal pressure based on internal sensors), which can look like brief firmness changes

How clinicians typically interpret these outputs

Clinicians usually ask:

Is the mattress inflated and supporting the patient appropriately?
Is it in alternating mode (if that is the intended therapy)?
Are there persistent low-pressure warnings suggesting leaks or disconnections?
Was the mattress accidentally left in static or max inflate mode after a procedure?

A simple bedside confirmation of alternation (when clinically appropriate) is to gently feel the surface: over time, you should be able to detect that different cell groups become firmer/softer in sequence. This is not a substitute for formal checks, but it can help catch situations where the pump is on but not actually alternating due to a settings change or a fault.

Common pitfalls and limitations

False reassurance: a functioning Alternating pressure mattress does not guarantee prevention of pressure injuries; skin checks and repositioning remain essential.
Incorrect settings: wrong weight/firmness can lead to bottoming out (too soft) or discomfort and shear risk (too firm).
Alarm fatigue: repeated silencing without correction can allow prolonged under-inflation.
Artifacts: patient movement, bed articulation, or heavy linens can affect perceived firmness and may trigger nuisance alarms.

Outputs should always be interpreted in the context of the patient’s overall condition and the facility’s prevention protocols. If the patient’s skin findings are worsening despite “normal” device indicators, reassess the whole plan: positioning, microclimate, nutrition, device-related pressure points, and whether a different support surface category is needed.

What if something goes wrong?

Problems with an Alternating pressure mattress often present as alarms, patient discomfort, visible deflation, or unexpected firmness changes. The goal is to protect the patient first, then troubleshoot systematically.

Rapid troubleshooting checklist (general)

Confirm the pump is plugged in and power is available at the outlet.
Check the pump power switch and that controls respond.
Inspect hoses for disconnection, kinks, or crushing under bed parts.
Verify any CPR/rapid deflation valve is fully closed and correctly seated (feature varies by manufacturer).
Look for obvious cover damage or fluid ingress.
If safe and per local practice, perform a quick support check (e.g., bottoming out assessment).
Reduce added layers: remove thick pads or extra mattresses that may interfere with performance (only if consistent with patient needs and policy).
If alarms persist, follow the model’s IFU steps and note any error codes.

A structured troubleshooting approach can reduce downtime:

Patient safety first: if the surface is clearly not supporting the patient, offload pressure and consider moving the patient to a safe alternative surface immediately.
Simple fixes next: reconnect hoses, remove kinks, confirm correct mode, and close any open valves.
Escalate early: persistent alarms usually indicate a problem that requires repair, replacement parts, or device swap.

Power interruption scenario (common and high-impact)

Power interruptions can occur due to unplugging during cleaning, transport, outlet failure, or facility-wide events. In these cases:

The mattress may remain inflated for a period, but alternation stops, and the risk profile changes.
If the patient is high risk, treat loss of power as time-sensitive: restore power, swap devices, or move to a safe alternative per policy.
During transport, confirm whether the pump can remain powered (or whether the unit expects unplugging). If unplugging is unavoidable, plan the trip to minimize time off therapy and increase skin checks afterward.

When to stop use (general safety triggers)

Stop using the device and move to a safe alternative surface per facility policy if:

The mattress cannot maintain inflation and the patient is not adequately supported
There is smoke, burning smell, unusual heat, fluid inside electrical components, or visible electrical damage
Alarms indicate a fault that cannot be corrected at the bedside
The patient experiences significant intolerance that cannot be resolved with appropriate adjustments and reassessment

Escalation pathways

Biomedical/clinical engineering: persistent alarms, suspected leaks, pump failures, damaged cables, repeated nuisance alarms, or cleaning-related water ingress.
Manufacturer or authorized service provider: recurring failures, unclear alarm codes, need for parts, or warranty/service contract questions (process varies by region).
Clinical escalation: worsening skin condition, pain, new redness over pressure points, or device-related pressure concerns—follow your clinical chain of command.

Where an equipment library exists, escalation may also include requesting a replacement unit immediately and tagging the faulty unit for rapid swap-out. For high-risk or critically ill patients, delays can have clinical consequences, so rapid exchange processes are valuable.

Documentation and reporting (general)

Good practice includes:

Documenting the issue, actions taken, and patient condition
Tagging and quarantining faulty equipment to prevent reuse
Completing internal incident reports for device-related safety events according to facility policy

Where possible, include specific information that helps engineering teams:

Time the problem was noticed
Alarm message or error code (exact wording)
Whether the issue began after transport, cleaning, or a bed move
Any visible damage (photos may be allowed under local policy)

Infection control and cleaning of Alternating pressure mattress

An Alternating pressure mattress can become contaminated through direct skin contact, body fluids, and high-touch handling during transfers and linen changes. Cleaning is therefore a core part of safe operations.

Cleaning principles (general)

Treat the mattress and pump as reusable medical equipment that requires a defined cleaning and disinfection process between patients.
Follow the manufacturer’s IFU and facility infection prevention policy for approved agents, dilution, contact time, and material compatibility.
Recognize that disinfection is not sterilization: most mattresses and pumps are disinfected, not sterilized, and should not be autoclaved unless the IFU explicitly states it is permitted.

Many facilities also distinguish between:

Routine daily cleaning (for example, wiping high-touch areas while the patient is on the mattress, if safe and permitted)
Terminal cleaning between patients (full cleaning/disinfection, inspection, and drying before reissue)

Disinfection vs. sterilization (simple definitions)

Cleaning: removal of visible soil and organic material (often with detergent).
Disinfection: use of chemicals to reduce microorganisms on surfaces to an acceptable level for clinical use.
Sterilization: elimination of all forms of microbial life; typically not applicable to large mattress systems unless components are designed for it (varies by manufacturer).

High-touch and high-risk areas

Prioritize:

Pump controls, handle areas, and power cord
Hose connectors and ports
Mattress cover seams, zipper areas, and any stitched regions
Areas near the foot of the bed that staff frequently touch during repositioning
Any crevices where fluid can pool

Also consider:

The underside of the mattress near straps/anchors (often overlooked during quick cleaning)
Hook points or brackets where pumps mount to bed frames
Any removable CPR valve covers or transport caps that are handled frequently

Example cleaning workflow (non-brand-specific)

Confirm the device is not in use and disconnect from the patient safely.
Unplug the pump before cleaning electrical components.
Wear facility-required PPE (personal protective equipment).
Remove linens and dispose or launder according to policy.
If there is visible soil, clean first with detergent/cleaner compatible with the cover material.
Apply an approved disinfectant to the mattress cover and pump exterior, maintaining required wet contact time.
Wipe connectors and hoses carefully; avoid forcing fluid into ports.
Allow surfaces to dry fully before reassembly and storage.
Inspect for tears, seam separation, or damaged connectors; remove from service if compromised.
Label or store as “clean” per your facility’s clean/dirty segregation practice.

Always defer to the specific IFU because material compatibility and allowable methods vary by manufacturer. In some facilities, covers may have additional instructions such as specific wipe types, restrictions on chlorine concentration, or guidance on laundering removable components.

Why drying and inspection matter more than they seem

Two common operational problems are:

Residual moisture trapped in folds or seams, which can contribute to odor, material degradation, and microbial persistence.
Small cover defects that are easy to miss but allow fluid ingress into the mattress interior. Once fluids enter internal layers, cleaning becomes much harder and the device may require repair or cover replacement.

For this reason, some services include a formal post-clean inspection step with adequate lighting, and a clear rule: any compromised cover is removed from circulation until repaired.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

A manufacturer is the company that markets the medical device under its name and is typically responsible for regulatory compliance, labeling, post-market surveillance, and the official Instructions for Use. An OEM (Original Equipment Manufacturer) may design or build components (or entire devices) that another company sells under its brand, or may supply key subassemblies such as pumps, compressors, valves, sensors, or control boards.

In some supply chains, you may also encounter “original design” relationships where one company designs a platform that is then branded by others. Regardless of terminology, what matters operationally is who is accountable for safety documentation, service pathways, and product updates.

Why OEM relationships matter operationally

OEM arrangements can influence:

Parts availability and lead times (especially for pumps and electronics)
Service documentation (what is shared with in-house biomedical teams vs. restricted)
Consistency of consumables (filters, hoses, covers) across product revisions
Support pathways (who provides training, updates, and repairs)

For Alternating pressure mattress systems, these factors directly affect uptime, turnaround after cleaning, and long-term total cost of ownership.

From a risk-management standpoint, it is also useful to know:

Whether accessories are cross-compatible across generations (helpful for fleet management) or tightly versioned (which can cause mismatches and downtime).
Whether the pump includes software/firmware that receives updates, and how updates are managed (particularly relevant if devices have data ports or connectivity in some settings).
How the manufacturer manages post-market feedback: when issues are reported, how quickly are corrective actions communicated to users, and through which channels?

Key Takeaways and Practical Checklist for Alternating pressure mattress

Confirm the clinical goal for using an Alternating pressure mattress before setup.
Treat the Alternating pressure mattress as one part of a prevention bundle, not the whole plan.
Verify bed–mattress compatibility and correct sizing to reduce entrapment risk.
Check the mattress cover for tears or seam failure before every patient use.
Ensure the pump and mattress model pairing is correct; compatibility varies by manufacturer.
Route hoses to avoid kinks, crushing, trip hazards, and wheel entanglement.
Plug the pump into a reliable power source and follow local electrical safety rules.
Allow the surface to fully inflate before placing a patient whenever the workflow allows.
Select the intended mode (alternating vs static) and re-check after procedures.
Use weight/firmness settings thoughtfully; incorrect settings can cause bottoming out or discomfort.
Document the surface type, mode, and initial checks according to facility policy.
Build alarm response into routines to avoid alarm fatigue and missed low-pressure states.
Never rely on alarm silencing as a long-term solution to persistent faults.
Continue regular skin inspections and repositioning unless protocol states otherwise.
Manage device-related pressure points from tubing, drains, collars, and splints.
Keep linen layers minimal and policy-compliant to preserve alternating performance.
Reassess fall risk because dynamic surfaces can feel less stable to mobile patients.
Use safe patient handling equipment for transfers; dynamic surfaces can increase shear during moves.
Include Alternating pressure mattress status and settings in every handover.
Have a backup plan for power failure and device malfunction on each unit.
Stop use if inflation cannot be maintained and the patient is not adequately supported.
Escalate persistent alarms to biomedical engineering rather than repeated bedside resets.
Quarantine and tag faulty equipment to prevent accidental reissue to another patient.
Align preventive maintenance schedules with manufacturer guidance and local risk policy.
Track accessories and consumables like filters, hoses, and covers to prevent downtime.
Standardize device models where feasible to reduce training variation and user error.
Ensure cleaning agents are compatible with cover materials per IFU and infection prevention policy.
Clean first, then disinfect; disinfection is not a substitute for soil removal.
Focus cleaning on pump controls, connectors, seams, and other high-touch areas.
Keep fluids out of electrical components and ports during cleaning.
Dry fully before storage to reduce odor, material degradation, and microbial persistence.
Audit cleaning turnaround times because delays can create bed block and unsafe substitutions.
Evaluate total cost of ownership, not only purchase price, during procurement decisions.
Confirm local service capability and spare parts availability before standardizing a model.
Train staff on CPR/rapid deflation features if present and relevant to your setting.
Treat patient discomfort reports seriously and reassess settings, positioning, and indications.
Avoid adding unapproved overlays that can impair performance and increase heat/moisture.
Use incident reporting pathways for device failures and near misses to improve systems.
Involve nursing, wound care, biomedical engineering, and procurement in product evaluations.
Recheck settings after bed moves, imaging, or transport because modes may change unintentionally.
Consider how head-of-bed elevation and sliding affect shear; adjust positioning strategies accordingly.
Ensure “clean” labeling is reliable so contaminated surfaces are not accidentally reissued.
Build a rapid swap-out process for high-risk patients when pumps fail or alarms persist.
