Forced air warming unit OR: Overview, Uses and Top Manufacturer Company

Introduction

Forced air warming unit OR is a commonly used piece of hospital equipment designed to help maintain a patient’s body temperature by delivering warmed air through a specialized blanket or gown. It is most often associated with the operating room (OR), but it may also be used in other perioperative and acute-care areas where patients are at risk of becoming cold.

Unintended hypothermia (a drop in body temperature) can occur during anesthesia and surgery because of heat loss from exposed skin, cool operating environments, and the effects of anesthetic drugs on the body’s normal temperature regulation. Many hospitals therefore build “temperature management” into routine perioperative workflows, and forced-air warming is one of the most widely recognized approaches.

This article is written for two overlapping audiences:

• Learners (medical students, residents, and trainees) who want a clear mental model of what the device does, how it is used, and what safety issues to watch for.
• Hospital decision-makers (administrators, clinicians, biomedical engineers, procurement teams, and operations leaders) who need practical information about setup, training, maintenance readiness, infection control, and service considerations.

You will learn what Forced air warming unit OR is, when it is typically used (and when it may not be appropriate), what you need before starting, basic operation, patient safety practices, how to interpret device outputs, troubleshooting basics, cleaning and infection prevention principles, and a high-level global market overview. This is general educational content only; always follow local policy and the manufacturer’s instructions for use (IFU).

What is Forced air warming unit OR and why do we use it?

A Forced air warming unit OR is a clinical device that generates a controlled flow of warmed air and delivers it to the patient via a compatible disposable or reusable warming blanket (sometimes called a “warming cover,” “forced-air blanket,” or “convective warming blanket”). The goal is to reduce heat loss and support maintenance of normothermia (normal body temperature) during procedures and recovery.

Clear definition and purpose

At its core, the device is a heater-blower system with basic control electronics:

• A fan draws in ambient air.
• Air passes through filtration (type and efficiency vary by manufacturer).
• A heating element warms the air to a selected level.
• Warm air is pushed through a hose into a perforated blanket that distributes heat across a broad surface area.

This is convective warming: heat is transferred from moving warm air to the patient’s skin and the thin layer of air trapped around the body under surgical drapes or bedding. The system is intended to provide gentle, distributed warming rather than focal heating of a small point.

Common clinical settings

Despite the “OR” label in Forced air warming unit OR, use is not limited to a single room type. Common settings include:

• Preoperative holding / induction areas to begin warming before anesthesia (often called “pre-warming”).
• Operating rooms during general anesthesia, regional anesthesia, and monitored anesthesia care (MAC), depending on the case and protocol.
• Post-anesthesia care unit (PACU) to help rewarm patients and reduce postoperative discomfort from feeling cold.
• Labor and delivery in selected scenarios (facility-specific).
• Emergency department (ED), intensive care unit (ICU), and procedure suites when temperature management is part of resuscitation or comfort care pathways (policy-dependent).

In low-resource settings, forced-air warming may be concentrated in tertiary centers, while smaller facilities may rely more on passive warming (blankets) or alternative active warming methods.

Key benefits in patient care and workflow

Benefits vary by patient, procedure, and local practice, but hospitals often adopt forced-air warming because it can be:

• Fast to deploy with standardized consumables (blankets in multiple sizes and shapes).
• Compatible with many surgical positions (supine, lateral, lithotomy) when the correct blanket design is chosen.
• Relatively simple to operate for trained staff, with straightforward controls and alarms.
• Scalable operationally, because it fits into perioperative workflows (case carts, warming bundles, temperature documentation).

From an operations perspective, these devices can support consistent practice across multiple ORs, especially when paired with a clear protocol for temperature monitoring, blanket selection, documentation, and cleaning.

Mechanism of action in plain language

The unit does not “heat the blood” directly. It warms the skin and the air layer around the patient, and the body’s circulation then distributes heat inward. The effectiveness depends on real-world factors such as:

• How much of the patient’s surface area can be covered safely
• Whether the blanket can inflate and distribute air evenly
• How much heat the patient is losing to the environment (cold prep solutions, exposed cavities, cool room temperatures, irrigation fluids)
• The patient’s baseline temperature and physiologic reserves

Forced-air warming is therefore best thought of as one component of a broader temperature management plan, which may also include warmed IV fluids, warmed irrigation, passive insulation, and environmental controls.

How medical students typically encounter or learn this device in training

Trainees most often meet Forced air warming unit OR in perioperative rotations:

• Anesthesiology: selecting warming methods, monitoring temperature, preventing hypothermia, troubleshooting alarms during surgery.
• Surgery: understanding draping constraints, incision access, and how warming interacts with positioning and sterile fields.
• Perioperative nursing: device setup, blanket placement, documentation, and room turnover cleaning.
• Biomedical engineering exposure: preventive maintenance (PM) stickers, electrical safety checks, and device readiness.

A practical learning milestone is recognizing that the device output (what you set on the unit) is not the same as the patient’s core temperature. Patient temperature must be monitored separately per local standards.

When should I use Forced air warming unit OR (and when should I not)?

Use decisions should be guided by local protocols, the clinical team’s judgment, and the manufacturer’s IFU. The points below are general patterns rather than prescriptions.

Appropriate use cases (common patterns)

Forced air warming is commonly considered when patients are at risk of becoming cold during or after care. Examples include:

• Procedures under anesthesia or deep sedation, where normal temperature regulation and behavioral responses (shivering, moving, asking for a blanket) are reduced.
• Longer procedures or cases involving large exposed surface area.
• Cold environments (many ORs and procedure rooms are kept cool for staff comfort, equipment requirements, or infection prevention strategies).
• Pre-warming workflows in pre-op holding to reduce the initial drop in temperature that can occur after anesthesia induction.
• Postoperative rewarming in PACU for patients who are cold, uncomfortable, or shivering (based on local pathway and monitoring practices).

From a hospital operations standpoint, forced-air warming is often integrated into a “bundle” approach: assess risk, apply active warming when indicated, monitor temperature, document, and respond to deviations.

Situations where it may not be suitable

There are circumstances where forced-air warming may be limited, deferred, or replaced by other warming methods. Examples include:

• When the planned blanket placement conflicts with surgical access or positioning, and an alternative blanket design (or alternative warming modality) is not feasible.
• When local infection prevention policy restricts convective warming in specific rooms or for specific procedure types. Policies vary and may change with emerging evidence or local risk assessments.
• When the patient’s skin condition makes blanket placement unsafe, such as fragile skin, extensive wounds, pressure injuries, or burns in areas that would be covered. Suitability depends on clinical context and the IFU.
• When the patient is already too warm (e.g., febrile or hyperthermic). Temperature management should be individualized and monitored.
• When the device cannot be used safely in the environment, such as MRI areas unless the system is explicitly MRI-conditional (varies by manufacturer).

Safety cautions and contraindications (general, non-prescriptive)

Contraindications and warnings are manufacturer- and blanket-specific. Common safety themes across many forced-air warming systems include:

• Do not use the hose alone (sometimes called “hosing”) to blow hot air directly onto the patient; this can create localized overheating and risk of thermal injury.
• Do not use non-compatible blankets or improvised coverings. Systems are designed as matched components, and off-label combinations can change airflow, temperature distribution, and alarm behavior.
• Avoid occluding the blanket’s air outlets (for example, by tightly tucking, compressing with heavy objects, or layering incompatible materials), because uneven airflow can increase the risk of hotspots.
• Keep the unit intake unobstructed and away from dust, lint, and fluids to reduce performance problems and contamination risk.
• Use caution with patients who cannot communicate discomfort (anesthetized, sedated, neonates/infants, cognitively impaired) because early symptoms of overheating may not be reported.

Emphasize clinical judgment, supervision, and local protocols

For learners: forced-air warming is not a “set and forget” tool. It is a medical equipment intervention that should be supervised appropriately, integrated with patient temperature monitoring, and adjusted based on the patient’s condition and the procedure’s needs.

For operations leaders: safe use depends less on the brand name and more on the system around it—training, documentation, maintenance readiness, blanket supply chain, infection prevention policy, and a culture that encourages reporting and learning from near-misses.

What do I need before starting?

Starting safely and consistently requires more than just switching the device on. Think in four buckets: equipment, environment, people, and process.

Required setup, environment, and accessories

Typical requirements include:

• Forced-air warming unit (the blower/heater base), on a stable surface or approved mounting solution.
• Compatible hose (often integrated or detachable depending on the model).
• Compatible warming blanket(s) in the correct size and design (upper-body, lower-body, full-body, underbody, pediatric/neonatal variants; availability varies by manufacturer).
• Power source appropriate for the unit’s voltage and plug type (important for facilities with mixed electrical standards).
• A separate patient temperature monitoring method per local protocol (the warming unit itself typically does not measure core temperature).
• Space planning to keep the intake clear, reduce trip hazards, and prevent the unit from being splashed with fluids.

Consumables planning matters operationally: if the correct blanket type is not available at case start, staff may improvise—which increases risk.

Training and competency expectations

A common failure mode in perioperative warming is not device malfunction, but inconsistent setup. Consider competency expectations such as:

• Knowing where the unit is stored and how it is transported safely
• Selecting the correct blanket for the case and patient size
• Correct blanket placement and draping integration
• Recognizing and responding to alarms
• Documenting use and patient checks
• Cleaning steps between patients/cases

Facilities often address this through onboarding, annual skills validation, in-service training from the vendor/manufacturer, and “super-user” models in the OR and PACU.

Pre-use checks and documentation

Before each use, many teams perform a quick readiness check. Specific steps vary by model, but common elements include:

• Visual inspection: cracks in housing, damaged cord, loose controls, missing labels, damaged hose, signs of fluid ingress.
• Cleanliness check: no visible soil on surfaces; unit stored appropriately.
• Preventive maintenance status: asset tag present, PM sticker current, no outstanding “do not use” tags.
• Functional check: power on, verify airflow, confirm controls respond, ensure alarm self-test (if present) completes.

Documentation practices vary widely, but often include:

• Start/stop time of active warming
• Blanket type used
• Device setting used (as recorded on the device)
• Patient temperature values from the patient monitor (not from the warmer)
• Skin checks and any adverse observations

Operational prerequisites: commissioning, maintenance readiness, consumables, and policies

For hospital leaders and biomedical teams, “ready to use” requires upstream work:

• Commissioning: incoming inspection, electrical safety testing as required, asset registration, user orientation.
• Preventive maintenance plan: filter change schedules (if applicable), functional verification, calibration checks (if relevant), and documentation.
• Service readiness: defined pathway for repairs, loaners, and escalation to manufacturer; spare parts availability varies by manufacturer.
• Consumables management: blanket SKUs standardized, par levels set, storage planned, and waste disposal considered.
• Policies and procedures: temperature management protocol, cleaning procedure aligned with IFU, and incident reporting expectations.

Roles and responsibilities (clinician vs. biomedical engineering vs. procurement)

Clear role separation reduces gaps:

• Clinicians (anesthesia, perioperative nursing, procedural staff): select and apply warming based on protocol and clinical needs; monitor patient response; document; stop use if safety concerns arise.
• Biomedical/clinical engineering: inspect, maintain, test, repair, manage recalls/alerts, and advise on safe integration with other hospital equipment.
• Procurement/supply chain: contract management, consumables standardization, vendor qualification, forecasting, and ensuring compatible blankets are always available.
• Infection prevention and environmental services (EVS): define cleaning/disinfection products and workflows consistent with the IFU and facility policy.

How do I use it correctly (basic operation)?

Workflows vary by model and facility, but most forced-air warming systems follow a similar pattern. Always follow the specific IFU and your institution’s perioperative warming protocol.

Basic step-by-step workflow (commonly applicable)

1. Confirm the plan – Verify that active warming is appropriate per local protocol and team decision-making. – Ensure patient temperature monitoring is planned and available.

2. Choose the correct blanket – Select a blanket designed for the patient’s size and the surgical site. – Check packaging integrity and product labeling (correct model, single-use vs reusable, expiration if applicable).

3. Position the blanket appropriately – Place the blanket as directed in the IFU (for example, upper-body blanket for lower abdominal surgery, or underbody blanket when access to the front is needed). – Keep perforations unobstructed and avoid folding that could block airflow. – Ensure lines, monitoring cables, and pressure points are managed safely.

4. Place and power the unit – Position the Forced air warming unit OR so that the air intake is clear and the unit is stable. – Connect to an appropriate electrical outlet (avoid overloading power strips; follow local electrical safety policy).

5. Connect hose to blanket (and verify secure fit) – Attach the hose to the blanket connection port as designed. – Ensure the hose is not kinked, crushed, or placed where staff may trip.

6. Turn the unit on and select a setting – Allow the unit to complete any start-up self-checks. – Select the intended warming level (often presented as presets such as low/medium/high; exact setpoints vary by manufacturer).

7. Verify airflow and blanket inflation – Confirm warm air is flowing and the blanket inflates/distributes air evenly. – Re-check that the blanket does not interfere with the sterile field or required access.

8. Monitor and document – Monitor patient temperature using the patient monitoring system as per local standards. – Perform periodic skin checks when feasible and appropriate. – Document settings and observations per policy.

9. End of use – Turn the unit off before disconnecting. – Dispose of single-use blankets as clinical waste per local policy. – Clean and disinfect the unit’s exterior surfaces as required. – Store the unit to protect it from dust and damage.

Typical settings and what they generally mean

Because designs vary, focus on the concept rather than exact numbers:

• Lower settings are often used for maintenance warming or for patients at higher risk of overheating.
• Higher settings may be used for more rapid warming when clinically appropriate, with closer monitoring.
• Some devices include an ambient or fan-only mode; use depends on local workflow and the IFU.

A key teaching point: the setting is the device’s air delivery target, not the patient’s core temperature. Patient temperature response can lag behind changes in setting.

Steps that are commonly universal across models

Across many systems, the most “universal” safety steps are:

• Use only compatible blankets and accessories.
• Never use hose-only warming on the patient.
• Keep intakes and vents unobstructed.
• Ensure blanket airflow is even and not blocked.
• Pair the device with patient temperature monitoring and documentation.

How do I keep the patient safe?

Patient safety with Forced air warming unit OR is achieved through layered controls: correct setup, appropriate monitoring, timely response to problems, and strong institutional processes. The device can be used safely in many settings, but misuse or complacency can lead to harm.

Safety practices and monitoring (what teams commonly do)

Common patient-safety practices include:

• Baseline temperature check before active warming begins (method depends on setting).
• Ongoing temperature monitoring during anesthesia and recovery per local standard of care and protocol.
• Skin integrity checks when feasible, especially at:
• Edges of the blanket
• Pressure points (sacrum, heels, scapulae)
• Areas with impaired sensation or circulation
• Pediatric and neonatal skin (more vulnerable to injury)

Because anesthetized or sedated patients cannot reliably report discomfort, visible checks and temperature trending become even more important.

Prevent thermal injury (burns) and overheating

Thermal injury risk is usually associated with preventable setup problems. Key general controls include:

• Use the correct blanket design so heat is distributed, not focused.
• Avoid compressing the blanket under heavy equipment or tight tucking that blocks airflow pathways.
• Do not add improvised coverings that change airflow (for example, plastic drapes or non-approved layers) unless your protocol and IFU explicitly support it.
• Keep the patient dry: wetness from prep solutions or pooled fluids can change heat transfer and may contribute to skin problems. Follow the IFU and local protocol around prep and draping.
• Adjust warming levels thoughtfully and reassess rather than leaving the device at a higher setting for the entire case without monitoring.

Alarm handling and human factors

Most units provide alarms for conditions such as overheating, blocked airflow, or internal faults (exact alarm logic varies by manufacturer). Human factors issues commonly seen in busy ORs include:

• Alarms being missed due to ambient noise or music
• The unit being placed behind drapes or equipment where indicators are not visible
• Staff assuming “someone else” is watching the warmer

Good practice is to assign responsibility clearly (often anesthesia or circulating nurse, depending on local policy) and to ensure alarms are audible and the unit is placed where staff can see it.

Follow facility protocols and manufacturer guidance

Safety is strongest when the facility aligns:

• A written temperature management protocol
• A defined device setup checklist
• Manufacturer IFU training and quick-reference guides
• Competency validation for new staff and traveling staff
• Standardized consumables to reduce setup variability

Facilities operating across multiple sites (or across countries) often benefit from standardizing on a smaller number of models, because training and consumables complexity increases with device diversity.

Risk controls, labeling checks, and incident reporting culture

For a safety-focused program, consider operational risk controls such as:

• Label checks at point of use: correct blanket, correct connector, intact packaging.
• Asset control: “do not use” tagging when a unit fails a check.
• Recall/alert management: biomedical engineering reviews manufacturer notices and ensures action is taken.
• Near-miss and incident reporting: encourage reporting of events like “hose not connected,” “wrong blanket opened,” “unit found dirty,” or “alarm silenced and forgotten.” These are leading indicators that allow prevention before patient harm.

How do I interpret the output?

A Forced air warming unit OR typically provides device-focused outputs, not patient-focused outputs. Understanding this distinction prevents a common error: assuming the patient is warm because the device is set to a high warming level.

Types of outputs/readings you may see

Depending on the model, the user interface may display or indicate:

• Selected warming level (preset or numeric; varies by manufacturer)
• Operational status (heating, fan running, ready)
• Alarm codes or warning lights (e.g., airflow obstruction, over-temperature, internal fault)
• Filter or maintenance indicators (varies by manufacturer)
• Timer or usage indicators (varies by manufacturer)

These outputs describe what the machine is doing, not the patient’s core temperature.

How clinicians typically interpret them

In clinical practice, interpretation usually follows a simple logic:

• If the blanket inflates appropriately and the unit indicates normal operation, the device is likely delivering warmed air as intended.
• The patient’s actual response is assessed using patient temperature monitoring and clinical observation (e.g., shivering in PACU, patient comfort, temperature trend).

Common pitfalls and limitations

Common pitfalls include:

• Equating set temperature with patient temperature: the patient may still be cold if heat loss exceeds heat gain, if the blanket is poorly placed, or if the covered surface area is small.
• False reassurance from blanket inflation: a blanket can inflate even if airflow distribution is uneven or if parts are occluded.
• Probe-related artifacts: patient temperature readings can be inaccurate if a probe is displaced, poorly sited, or affected by environmental factors. Clinical correlation matters.
• Workflow gaps: warming started late, blanket opened but not connected, or device left off after room turnover.

The safest approach is to treat the warmer output as a process indicator (device functioning) and the patient temperature as the clinical outcome indicator (patient warming), and to reconcile both with the clinical situation.

What if something goes wrong?

Problems with forced-air warming can range from minor setup issues to situations requiring immediate discontinuation and escalation. The response should prioritize patient safety, then equipment integrity, then documentation and reporting.

Troubleshooting checklist (practical and general)

If the patient is not warming as expected or the unit alarms:

• Confirm the unit is powered on and not connected to a switched-off outlet.
• Check the cord and plug for damage and ensure the connection is secure.
• Verify the hose is connected firmly to both unit and blanket.
• Look for kinks, crushing, or occlusion of the hose.
• Ensure the blanket is the correct type and placed per IFU.
• Check that blanket air outlets are not blocked by tight tucking, heavy objects, or incompatible layers.
• Make sure the unit’s air intake is not obstructed by drapes, dust covers, linen, or the wall.
• If an alarm persists, follow the device’s on-screen guidance (if present) and local policy for removing from service.

If the concern is patient-related (e.g., redness, discomfort, excessive warmth, unexpected temperature rise):

• Stop or reduce active warming as appropriate per local protocol.
• Assess skin and overall clinical status.
• Escalate to the supervising clinician and document findings.

When to stop use (general red flags)

Stop using the device and switch to an alternative warming strategy (per local protocol) if:

• There are signs of thermal injury or suspected skin damage.
• You detect smoke, burning smell, unusual heat, or fluid ingress into the unit.
• The unit repeatedly alarms and you cannot resolve it quickly.
• The device fails self-checks or displays a critical fault message (wording varies by manufacturer).
• The unit appears electrically unsafe (sparking, damaged cable, exposed wiring).

When to escalate to biomedical engineering or the manufacturer

Escalate to biomedical/clinical engineering when:

• A unit fails a pre-use check or functional check.
• Alarms recur across multiple cases despite correct setup.
• The device has been dropped, contaminated internally, or exposed to fluids.
• Preventive maintenance is overdue or a filter/part replacement is required.

Escalate to the manufacturer (often via biomedical engineering or procurement) when:

• A fault code suggests internal component failure.
• Replacement parts or proprietary consumables are required.
• There are questions about compatibility, IFU interpretation, or reported safety notices.

Documentation and safety reporting expectations

General best practice is to document:

• What happened (patient and device observations)
• Actions taken (stopped warming, changed blanket, removed device from service)
• Patient assessment (as appropriate within your scope and local policy)
• Equipment identifiers (asset tag, model, serial number if available)
• Who was notified (supervisor, biomedical engineering)

Many facilities also expect entry into an internal incident reporting system for suspected device-related events, even if no harm occurred, to support system learning.

Infection control and cleaning of Forced air warming unit OR

Forced-air warming involves airflow, patient contact via blankets, and repeated use across many cases. Infection prevention therefore depends on disciplined cleaning, correct consumable use, and adherence to both the IFU and facility policy.

Cleaning principles (practical overview)

• Cleaning removes visible soil (dust, blood, body fluids) and is usually the first step.
• Disinfection reduces microbial load using an approved chemical agent and contact time.
• Sterilization eliminates all forms of microbial life and is not typically applicable to the external surfaces of a forced-air warming unit in routine OR workflow.

A Forced air warming unit OR is generally treated as non-sterile medical equipment. The disposable blanket typically serves as the patient-contact interface; in many systems, blankets are single-use and discarded after each patient (confirm per manufacturer labeling).

High-touch points to prioritize

High-touch surfaces often include:

• Control panel and buttons/knob
• Handle and push points
• Hose exterior and connection points
• Power cord and plug (as allowed by policy)
• Exterior vents/grilles (avoid pushing fluid into the unit)
• Mounting stand surfaces, basket, or brackets (if used)

Example cleaning workflow (non-brand-specific)

Always follow the IFU and infection prevention guidance. A typical between-case approach may look like:

1. Turn the unit off and unplug if required by local policy before cleaning.
2. Don appropriate PPE (personal protective equipment) based on expected contamination.
3. Remove and discard single-use blankets as clinical waste.
4. If the hose is reusable, wipe the hose exterior and connector surfaces with an approved disinfectant.
5. Wipe the control panel and exterior housing using a facility-approved disinfectant wipe, ensuring correct contact time.
6. Avoid excessive wetting and do not allow fluids to enter vents or electrical openings.
7. Allow surfaces to air dry fully.
8. Confirm the unit is clean, intact, and stored to minimize recontamination.

Some facilities implement scheduled “deep cleaning” or periodic inspection steps coordinated with biomedical engineering and infection prevention teams, especially in high-throughput ORs.

Filters, internal pathways, and policy variability

Whether internal filters are user-serviceable, how often they are changed, and what filtration level is used varies by manufacturer and model. Operationally:

• Filter change responsibilities should be clearly assigned (often biomedical engineering).
• Filter change schedules should be tracked like other PM tasks.
• Units should be stored to minimize dust accumulation, because dust can affect performance and cleanliness.

Emphasize IFU and facility policy

Infection prevention is not one-size-fits-all. OR airflow design, local surveillance priorities, and national guidance differ by country and facility. The safest universal instruction is to align practice with:

• Manufacturer IFU (including approved disinfectants)
• Facility infection prevention policy
• Biomedical engineering maintenance procedures

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

In medical equipment, a manufacturer is the entity whose name appears on the product label and who is responsible for the finished device’s quality system, regulatory compliance, labeling, and post-market surveillance (requirements vary by jurisdiction).

An OEM (Original Equipment Manufacturer) may produce components or even complete devices that are then branded and sold by another company. OEM relationships are common across healthcare technology (for example, shared platforms, outsourced manufacturing, or private-label consumables).

How OEM relationships can impact quality, support, and service

OEM and private-label structures are not inherently good or bad, but they change operational realities:

• Service documentation and parts may be controlled by the branded manufacturer even if the OEM built the device.
• Consumables compatibility (blankets, hoses, filters) can be tightly controlled and may affect total cost of ownership.
• Support pathways may differ across regions, especially where distribution is handled by third parties.
• Update cycles (software, labeling changes, product revisions) can vary and should be tracked by biomedical engineering.

Import dependence is common for many device categories, and procurement often values strong distributor support and training. Access in rural areas may be limited by budgets and service reach.

Key Takeaways and Practical Checklist for Forced air warming unit OR

• Treat Forced air warming unit OR as part of a temperature-management system, not a standalone solution.
• Confirm your facility’s protocol for when active warming is indicated before starting.
• Ensure patient temperature monitoring is available; the warmer does not measure core temperature.
• Select a blanket design that matches the surgical site, patient size, and positioning plan.
• Use only manufacturer-compatible blankets, hoses, and accessories to reduce safety risk.
• Never direct the hose output at the patient without a designed blanket (“hosing” risk).
• Keep blanket air outlets unobstructed; avoid tight tucking or compressing the blanket.
• Keep the unit’s air intake clear of drapes, linen, walls, and dust accumulation.
• Position the unit to reduce trip hazards and prevent fluid splashes into vents.
• Perform a quick pre-use visual inspection for cracks, damage, or missing labels.
• Check preventive maintenance status and do not use equipment with “do not use” tags.
• Power on early enough to complete self-checks without delaying case start.
• Confirm the blanket inflates evenly and warm air is flowing after activation.
• Document the device setting and start time according to local perioperative charting rules.
• Reassess the warming level based on patient temperature trend, not just time elapsed.
• Increase vigilance when patients cannot report discomfort (sedation, anesthesia, pediatrics).
• Inspect skin when feasible, especially at pressure points and blanket edges.
• Keep the patient dry and manage pooled prep solutions per local OR practice.
• Respond to alarms promptly; avoid silencing alarms without resolving the cause.
• If alarms recur, remove the unit from service and notify biomedical engineering.
• Stop use immediately for suspected burns, smoke, burning odor, or fluid ingress.
• Use facility-approved disinfectants and follow required contact times for disinfection.
• Clean high-touch points every case: controls, handle, hose exterior, and exterior housing.
• Prevent disinfectant liquid from entering vents or electrical openings during cleaning.
• Dispose of single-use blankets appropriately; do not reuse unless labeled for reuse.
• Standardize blanket SKUs where possible to reduce wrong-item opening and waste.
• Plan par levels for blankets so correct types are available for every scheduled list.
• Include warming devices in OR setup checklists and turnover checklists.
• Train new staff and traveling staff on local warming workflows and safety warnings.
• Clarify who “owns” the warmer during the case (anesthesia vs nursing) to avoid gaps.
• Track device downtime and common faults to guide service planning and replacement cycles.
• Consider total cost of ownership: consumables, filters, service contracts, and loaner access.
• Validate electrical safety and grounding requirements during commissioning and PM.
• Align infection prevention policy, biomedical maintenance, and clinical workflow into one process.
• Maintain an incident reporting culture that treats near-misses as learning opportunities.
• For multi-site systems, reduce model variation to simplify training and spare parts support.
• For low-resource settings, prioritize devices with strong local service and consumables continuity.
• Confirm storage practices minimize dust and damage between uses.
• Include device model/serial and blanket type in event documentation when problems occur.
• Review manufacturer IFU updates periodically; practices can change with product revisions.
• Integrate warming documentation into perioperative dashboards if your facility uses them.
• Ensure procurement evaluates distributor capability, not only purchase price.
• Keep a backup warming plan available for high-risk cases in case of device failure.
• Use interdisciplinary review (OR, anesthesia, IP, biomed) when policies change.
