Oxygen concentrator: Overview, Uses and Top Manufacturer Company

Introduction

An Oxygen concentrator is a medical device that takes in ambient air and delivers oxygen-enriched gas for patients who need supplemental oxygen. Unlike a cylinder, it does not “store” oxygen; it concentrates oxygen from room air using internal filters and adsorption technology, then provides a controlled output through standard oxygen tubing and patient interfaces.

In hospitals and clinics, Oxygen concentrator systems can reduce dependence on cylinder deliveries, support continuity of care during supply disruptions, and expand access to oxygen therapy in settings where piped medical gas is limited. In home care, they are widely used to support long-term oxygen therapy and to reduce logistics for patients who require ongoing oxygen support under clinical supervision.

This article is designed for medical students, residents, and trainees learning oxygen delivery basics, and for hospital administrators, clinicians, biomedical engineers, and procurement teams responsible for safe deployment, maintenance, and purchasing. You will learn what an Oxygen concentrator does, common clinical uses and limitations, practical setup and operation steps, safety and monitoring principles, troubleshooting approaches, cleaning and infection prevention considerations, and a high-level, globally aware view of the market and supply ecosystem.

Information here is general and educational. Always follow your facility’s protocols and the manufacturer’s instructions for use (IFU).

What is Oxygen concentrator and why do we use it?

An Oxygen concentrator is hospital equipment designed to provide supplemental oxygen by separating oxygen from the other gases in room air. Its purpose is to support patients who require oxygen therapy when clinically indicated—whether in an inpatient ward, emergency department, outpatient facility, or home setting.

Common clinical settings where it is used

You may encounter an Oxygen concentrator as medical equipment in:

• General wards and step-down areas for patients requiring low-to-moderate oxygen flows (within device capability).
• Outpatient clinics and procedure areas where oxygen is needed intermittently and pipeline oxygen is not available.
• Home care and long-term care programs where stable oxygen delivery is needed for extended periods.
• Rural clinics and low-resource facilities where cylinders are difficult to refill or transport reliably.
• Disaster response and surge capacity planning, as a supplemental oxygen source when infrastructure is strained.

Actual use depends on local policies, staffing, and whether the Oxygen concentrator model is intended for clinical (hospital) versus home environments.

Key benefits in patient care and workflow

Compared with relying only on cylinders, an Oxygen concentrator can offer:

• Continuous oxygen availability as long as electrical power and the device are functioning.
• Reduced oxygen logistics burden, including fewer deliveries, fewer cylinder changes, and less storage space pressure.
• More predictable bedside workflow, particularly in facilities without piped medical gas.
• Support for decentralised care, including home-based oxygen programs when clinically appropriate and supported.

These benefits matter operationally: oxygen is both a therapy and a supply chain challenge, and concentrators shift part of that challenge from transportation to maintenance, power reliability, and training.

How it functions (plain-language mechanism)

Most Oxygen concentrator devices use a process commonly called pressure swing adsorption (PSA):

1. A compressor draws in room air through an inlet filter.
2. Air passes through molecular sieve material (often zeolite) that preferentially traps nitrogen.
3. The remaining gas becomes oxygen-enriched and is collected in a small reservoir.
4. Valves alternate between sieve beds to regenerate the material and maintain output.
5. A flow control system delivers oxygen to the patient through tubing.

Many models include alarms and indicators for power, flow restriction, temperature, and oxygen concentration status. Exact design details, sensors, and performance specifications vary by manufacturer.

How learners encounter this device in training

Medical students and trainees typically meet the Oxygen concentrator when learning:

• Oxygen as a prescribed therapy with indications, targets, and monitoring requirements (per local protocols).
• Differences between oxygen sources (pipeline, cylinder, concentrator) and why the source changes operational risk.
• How to use interfaces (nasal cannula, masks) and interpret the relationship between flow rate, patient breathing pattern, and oxygenation.
• Practical ward skills: checking that oxygen is actually flowing, responding to alarms, and ensuring a backup plan for transport or power interruptions.

For many trainees, the most important takeaway is that an Oxygen concentrator is a clinical device with failure modes—and those failure modes must be anticipated, monitored, and managed.

When should I use Oxygen concentrator (and when should I not)?

An Oxygen concentrator is used when a clinician determines that a patient needs supplemental oxygen and the selected device can safely deliver the required support within its labeled capabilities. The decision is not only clinical; it is also operational (power, maintenance status, alarms, staffing, and backup oxygen availability).

Appropriate use cases (general)

Typical appropriate scenarios include:

• Stable patients needing supplemental oxygen within the flow and concentration performance envelope of the device (varies by manufacturer).
• Long-duration oxygen needs where cylinders would require frequent replacement.
• Facilities without piped oxygen, where concentrators provide bedside oxygen without a central plant.
• Home oxygen programs with structured patient education, follow-up, and equipment servicing.
• Step-down from higher-acuity oxygen sources, when clinically appropriate and consistent with local pathways.

Situations where it may not be suitable

An Oxygen concentrator may be a poor fit when:

• Demand exceeds device capacity, such as very high flow requirements or when multiple patients are connected without a device designed for that use.
• A care area needs precise, high-stability oxygen blending (for example, where a controlled fraction of inspired oxygen is required by protocol). Some setups require an oxygen/air blender and adequate source pressure; many concentrators are not designed for that role.
• Emergency resuscitation or rapidly escalating respiratory failure requires oxygen delivery methods beyond what the available concentrator can reliably provide.
• The environment has unreliable electricity and no effective backup power or oxygen contingency plan.
• The device is being considered for use in restricted environments (for example, MRI areas) where only specific equipment types may be permitted. Most Oxygen concentrator units are not intended for MRI rooms; local safety policy applies.

Safety cautions and general contraindications (non-clinical)

These are operational and safety concerns rather than patient-specific medical contraindications:

• Fire and ignition risk: Oxygen-enriched environments increase combustion risk; keep away from smoking, open flames, and spark sources.
• Electrical safety: Use grounded outlets, avoid damaged cables, and follow facility rules on extension cords and power strips.
• Heat and ventilation: Concentrators generate heat and need airflow; blocked vents can trigger overheating and reduced performance.
• Altitude and ambient conditions: Output performance can be affected by altitude, temperature, and humidity; check the IFU and facility acceptance testing criteria.
• Device condition and maintenance status: A concentrator overdue for preventive maintenance (PM), with clogged filters, or with recurring alarms should not be used until evaluated per policy.

Emphasize clinical judgment and local protocols

Oxygen therapy decisions should be made under qualified clinical supervision, following local guidelines for monitoring, escalation, and documentation. Device choice should align with the patient’s needs, the care setting, and the facility’s oxygen safety program.

What do I need before starting?

Safe use of an Oxygen concentrator depends on preparation in four areas: environment, accessories, people, and process.

Required setup, environment, and accessories

Common prerequisites include:

• Power and placement
• A reliable, grounded electrical outlet appropriate for the device rating.
• Physical clearance around vents (spacing requirements vary by manufacturer).
• Placement away from curtains, bedding, heaters, or other airflow obstructions.
• Patient delivery accessories
• Oxygen tubing of appropriate length and condition.
• A patient interface (for example, nasal cannula or mask) consistent with clinical orders and local policy.
• Optional: a humidifier bottle and compatible connector if humidification is used in your setting (varies by policy and patient population).
• Backup oxygen plan
• A cylinder or piped oxygen fallback for transport, power failure, or device malfunction.
• A regulator and appropriate connectors for the backup source, stored and checked per facility process.

Avoid improvising connectors or adapters. Use only approved accessories to reduce leak risk and misconnections.

Training and competency expectations

Because an Oxygen concentrator is clinical device infrastructure, competency should cover:

• Differentiating continuous flow vs pulse-dose (portable) modes where applicable, and understanding that pulse settings are not the same as liters per minute (L/min).
• Reading a flow meter correctly and confirming flow at the patient end.
• Recognising and responding to alarms (power failure, low oxygen concentration status, high temperature, no flow, etc.).
• Safe setup of humidification (if used), including spill prevention and infection prevention steps.
• Understanding escalation pathways: when to call respiratory therapy, the unit lead, biomedical engineering, or the vendor.

Competency requirements vary by facility and role.

Pre-use checks and documentation

A practical pre-use check often includes:

• Confirm the device has an asset tag, current safety label, and is within PM interval (per facility policy).
• Inspect the power cord, plug, casing, and wheels/handles for damage.
• Check that inlet filters are present and not visibly clogged; verify any required external filters are installed.
• Power on and allow any self-test or warm-up period specified by the IFU.
• Confirm flow control moves smoothly and flow is visible on the flow meter when set.
• Check oxygen concentration status indicator (if present) and alarm function (test per IFU).
• Document device ID and basic checks as required in the patient record and/or equipment log.

Operational prerequisites (commissioning, maintenance readiness, consumables, policies)

From an operations and biomedical engineering perspective, a concentrator program should include:

• Acceptance testing/commissioning on receipt: electrical safety, basic functional test, and oxygen concentration verification method (facility-defined; varies by model).
• A preventive maintenance schedule aligned to IFU: filter changes, compressor checks, sieve bed evaluation/replacement criteria, and oxygen sensor checks (if applicable).
• A consumables plan: filters, tubing, humidifier bottles, and any proprietary parts.
• Policies for storage, cleaning between patients, transport, and out-of-service tagging.
• A clear pathway for loaner units or surge capacity during repair downtime.

Roles and responsibilities

• Clinicians (physicians/advanced practice providers): determine the clinical need, prescribe oxygen therapy parameters per local standards, and set escalation thresholds.
• Nursing/respiratory therapy (or equivalent): set up the Oxygen concentrator, apply the interface, monitor the patient, document therapy, and respond to alarms.
• Biomedical engineering/clinical engineering: commissioning, PM, repairs, verification testing, recall/field action management, and technical training support.
• Procurement/supply chain: vendor qualification, service contracts, spare parts availability, total cost of ownership evaluation, and standardisation decisions.
• Facilities/engineering and safety teams: power infrastructure readiness, fire safety integration, and environmental constraints.

Clear role definition prevents “ownership gaps,” a common contributor to equipment-related incidents.

How do I use it correctly (basic operation)?

Workflows differ by model, but a safe, repeatable bedside process for an Oxygen concentrator is usually built around verify → set up → confirm output → apply → monitor → document.

A basic step-by-step workflow (non-brand-specific)

1. Verify the clinical order and patient identity according to facility policy.
2. Select the right device type (stationary vs portable; continuous flow vs pulse-dose) and confirm it can meet expected demand (per IFU).
3. Position the concentrator upright with adequate clearance for ventilation, away from heat sources and obstructions.
4. Connect to power using an appropriate outlet; avoid damaged cords or non-approved adapters.
5. Inspect filters and external condition (inlet filter present, vents clear, no cracks or fluid intrusion).
6. Turn the device on and allow the manufacturer-specified warm-up/self-test period (varies by manufacturer).
7. Attach accessories – Connect oxygen tubing securely to the oxygen outlet. – If using a humidifier bottle: fill with water type specified by policy/IFU, secure the cap, keep upright, and connect tubing correctly (device outlet → bottle → patient).
8. Set the flow or dose – For continuous flow: set the ordered L/min and confirm the flow meter reading at eye level. – For pulse-dose: set the prescribed setting and confirm the device is sensing breaths as intended (where applicable).
9. Confirm output – Check for flow at the patient end (feel/hear flow, or use facility-approved verification methods). – Review oxygen status indicator if available (some devices show percentage; others show a “normal/low” status).
10. Apply the interface to the patient and ensure comfort, correct positioning, and minimal leak (as relevant to the interface type).
11. Monitor and document per local protocol: oxygen delivery device, settings, patient response, and any alarms or issues.
12. Reassess regularly and during transitions (transport, imaging, change in clinical status, bedtime if pulse-dose is used), ensuring a backup oxygen plan.

Typical settings and what they generally mean

• Flow rate (L/min): a measure of gas flow leaving the device; it is not the same as the oxygen concentration percentage and does not directly equal the patient’s fraction of inspired oxygen (FiO₂).
• Pulse-dose setting: a device-specific scale that controls bolus delivery triggered by inspiratory effort; the numeric setting is not necessarily equivalent to L/min.
• Oxygen concentration indicator/status: may be a percentage display or a “normal/low oxygen” light; accuracy and thresholds vary by manufacturer.
• Alarms: commonly include power failure, no flow/flow restriction, low oxygen concentration status, and high temperature; exact alarm logic varies by manufacturer.

Calibration and verification (if relevant)

Many bedside users do not “calibrate” concentrators. However:

• Some programs require periodic verification of oxygen concentration using an external oxygen analyzer, performed by biomedical engineering or trained staff per policy.
• If a concentrator includes an internal oxygen sensor, it may need functional checks or replacement intervals that vary by manufacturer.

Always follow the IFU and your facility’s medical equipment management plan.

How do I keep the patient safe?

Safe use of an Oxygen concentrator is not only about turning the device on. It is about controlling predictable risks: hypoxia from inadequate delivery, hyperoxia from inappropriate delivery, fire hazards, device failures, and human factors.

Safety practices and monitoring (general)

Key safety practices include:

• Treat oxygen as a medication: ensure there is a documented clinical order and that the delivery method and settings match it.
• Monitor patient response: oxygenation should be assessed using the facility’s standard methods (often pulse oximetry) and clinical observation, with escalation pathways for deterioration.
• Verify actual flow delivery: confirm that flow reaches the patient and tubing is not kinked, crushed, or disconnected.
• Confirm device capability: do not assume all Oxygen concentrator units deliver the same flow range or concentration at all flows; performance varies by manufacturer and conditions.
• Plan for transitions: transport, imaging, power outages, or room changes are common points of failure; ensure backup oxygen is available and staff know how to switch sources safely.
• Maintain comfort and skin integrity: check for pressure areas from tubing/cannula, dryness, and patient tolerance; apply facility-approved protective measures.

Fire safety and environmental risk controls

Oxygen-enriched environments increase the risk and intensity of fire. Practical controls include:

• Enforce no smoking policies and clear signage where oxygen is in use.
• Keep the concentrator away from open flames, sparks, and high-heat devices (space heaters, some cooking equipment, etc.).
• Avoid use of oil-based or petroleum-based products near oxygen delivery equipment per local policy (risk varies; follow institutional guidance).
• Store and operate the device in a well-ventilated area with unobstructed vents.
• Do not cover the concentrator with cloth or place it under beds where airflow is restricted.

Alarm handling and human factors

Alarm response is a patient safety skill. Common human factors problems include alarm fatigue, misinterpretation of pulse-dose settings, and assumptions that “oxygen is flowing because the machine is on.”

Good practices:

• Know the alarm meanings for the specific model in your unit; keep quick-reference guides accessible.
• Do not silence alarms without identifying and addressing the cause.
• Use standard handoffs: document device type, setting, and any recent alarms during shift change and transfers.
• When a patient deteriorates, treat it as a patient first problem: assess the patient, verify oxygen delivery, and escalate clinically as required.

Labeling checks and incident reporting culture

From a safety and hospital operations standpoint:

• Check that maintenance labels (PM due date, service status) are current and the device is not tagged out of service.
• Ensure the unit is configured with approved accessories; avoid ad-hoc adapters.
• Encourage reporting of near misses (for example, low oxygen status alarms that were ignored, repeated power failures, or devices found without filters). A learning culture improves system reliability.

The safest Oxygen concentrator program is one where device checks, staff training, and escalation pathways are built into routine care—not treated as exceptions.

How do I interpret the output?

An Oxygen concentrator provides several outputs and indicators, but none should be interpreted in isolation. The central principle is clinical correlation: match device output with patient monitoring and the overall clinical picture.

Types of outputs/readings you may see

Depending on model, you may have:

• Flow meter reading (L/min): continuous flow output setting.
• Pulse-dose setting: device-specific dosing scale (not directly L/min).
• Oxygen concentration display or status indicator: may show a percentage or “normal/low” status; sensing method varies by manufacturer.
• Alarm indicators: power failure, high temperature, no flow/flow restriction, low oxygen concentration status, service required.
• Battery/charging status: on portable units.
• Hour meter/service indicator: useful for maintenance scheduling.

How clinicians typically interpret them

In routine care, clinicians often use a combination of:

• Device setting (flow or pulse setting) to understand the intended oxygen delivery.
• Patient oxygenation monitoring (commonly pulse oximetry) to confirm response.
• Clinical signs (work of breathing, mental status, hemodynamics) to detect deterioration early.

The flow number is not equivalent to inspired oxygen fraction (FiO₂). Actual inspired oxygen depends on the interface, patient inspiratory flow demand, breathing pattern, and mask fit or cannula position.

Common pitfalls and limitations

• Pulse-dose confusion: a “2” or “3” on a portable Oxygen concentrator is not universally equivalent to 2–3 L/min; confirm model-specific meaning.
• Performance at extremes: some concentrators may show reduced oxygen concentration at high flow settings or under stress (filter blockage, high ambient temperature); verify per IFU.
• Triggering failures (pulse-dose): if the device does not detect inspiratory effort reliably, the patient may receive less oxygen than expected.
• Tubing effects: long tubing, kinks, water accumulation, or loose connections can reduce effective delivery.
• Sensor and display limitations: oxygen concentration indicators may have warm-up time and may be designed for general status rather than precise measurement; accuracy varies by manufacturer.

False reassurance and false alarms

• A machine that is powered on may still fail to deliver adequate oxygen if the outlet is blocked, filters are clogged, or alarms are ignored.
• Conversely, alarms can sometimes be triggered by environmental factors (heat, airflow blockage) or accessory issues rather than a complete device failure.

Interpret concentrator output as part of a broader safety system: device indicator + patient monitoring + staff assessment + backup readiness.

What if something goes wrong?

Problems with an Oxygen concentrator can range from simple (kinked tubing) to serious (overheating, low oxygen concentration status, electrical faults). A structured response reduces harm.

A practical troubleshooting checklist

1. Assess the patient first and follow your clinical escalation pathway if they are deteriorating.
2. Switch to backup oxygen (cylinder or pipeline) if there is any doubt about delivery.
3. Check power – Is the unit plugged in securely? – Has a breaker tripped or outlet failed? – Is the device on battery (portable) and is the battery depleted?
4. Check flow delivery – Is the flow/dose set correctly? – Is the tubing connected to the correct port and not kinked? – Is the interface properly applied?
5. Check alarms and indicators – Identify the alarm type and follow the quick guide/IFU. – Look for low oxygen concentration status, high temperature, or no-flow alarms.
6. Check ventilation and overheating – Are vents blocked? – Is the device too close to a wall or soft furnishing? – Is the room unusually hot?
7. Check filters and accessories – Dirty inlet filters can reduce performance. – Humidifier bottles can leak or create back pressure if assembled incorrectly. – Water in tubing can obstruct flow; manage per policy.
8. If the problem persists, remove from service and use a backup unit/source.

When to stop use immediately (general)

Stop using the concentrator and follow facility safety procedures if you observe:

• Burning smell, smoke, sparking, or signs of electrical damage.
• Cracked casing, fluid ingress, or physical instability that could cause injury.
• Persistent low oxygen concentration status alarm or repeated failure to deliver flow despite checks.
• Overheating that does not resolve with repositioning and ventilation.

When to escalate to biomedical engineering or the manufacturer

Escalate when:

• Alarms persist after basic checks or recur frequently.
• The device fails acceptance criteria for oxygen concentration/flow verification (per facility program).
• The unit is overdue for PM or has unknown maintenance status.
• You suspect internal component failure (compressor issues, valve cycling abnormalities, sieve bed problems, sensor faults).

Biomedical engineering should evaluate, document, and decide on repair, quarantine, or vendor escalation. Manufacturer or authorized service support may be required for proprietary parts and software-enabled diagnostics.

Documentation and safety reporting expectations

Good documentation supports patient safety and system learning:

• Record the event in the patient record as applicable (therapy interruption, oxygen source change, patient response).
• Log the equipment issue using your facility’s incident reporting and equipment management systems.
• Tag the device as out of service with a clear description of the fault and your contact details.
• Preserve context: alarm codes/messages, environmental conditions, and accessories used can help identify root causes.

Infection control and cleaning of Oxygen concentrator

Infection prevention for an Oxygen concentrator focuses on external surfaces and patient-contact accessories. Internal gas pathways are generally not user-serviceable, so facilities rely on barriers (single-patient accessories) and cleaning/disinfection processes aligned with the IFU.

Cleaning principles

• Perform hand hygiene before and after handling the device and accessories.
• Use facility-approved cleaning and disinfectant products compatible with the device materials.
• Prevent liquid intrusion into vents and electrical areas.
• Treat patient-contact items as single-patient use unless the IFU explicitly supports reprocessing and your facility has a validated method.

Disinfection vs. sterilization (general)

• Cleaning removes visible soil and reduces bioburden.
• Disinfection uses chemical agents to inactivate microorganisms on surfaces (levels vary by product and policy).
• Sterilization is intended to eliminate all forms of microbial life and is not typically applied to the concentrator unit itself.

The Oxygen concentrator is usually managed with cleaning and surface disinfection, while patient interfaces and tubing are often disposed of or handled under a validated reprocessing workflow.

High-touch points to prioritise

Common high-touch areas include:

• Power switch and control knobs/buttons
• Flow meter area and oxygen outlet port
• Carry handle, side panels, and top surfaces
• Alarm reset/silence buttons and display screens
• Wheels and lower panels (often exposed to floor contamination)

Example cleaning workflow (non-brand-specific)

1. Don appropriate personal protective equipment (PPE) per facility policy.
2. Turn off the concentrator and unplug it (and remove battery if required by policy/model).
3. Remove and discard single-patient items (tubing, cannula/mask) per policy.
4. If a humidifier bottle was used, empty it safely and handle it according to your reprocessing/disposal process.
5. Wipe external surfaces with an approved disinfectant, ensuring the correct contact time.
6. Avoid saturating vents; do not spray directly into openings.
7. Allow surfaces to dry fully before returning the device to service or storage.
8. Replace or clean filters only as allowed by the IFU and facility policy.
9. Document cleaning if your unit tracks high-risk equipment reprocessing.

Always follow the manufacturer IFU and local infection prevention policy

Materials compatibility and approved chemicals vary by manufacturer. Some disinfectants can cloud plastics, damage seals, or degrade labels over time. Your infection prevention team and biomedical engineering department should align cleaning practices with IFU requirements and local risk assessments.

Medical Device Companies & OEMs

Understanding who makes an Oxygen concentrator—and who stands behind service and quality—is essential for procurement, maintenance planning, and incident management.

Manufacturer vs. OEM (Original Equipment Manufacturer)

• A manufacturer is the company that markets the product under its name and is typically responsible for the quality management system, labeling, technical documentation, and post-market support (requirements differ by jurisdiction).
• An OEM (Original Equipment Manufacturer) may build components (compressors, valves, sensors) or even complete devices that are then branded and sold by another company.
• Some products are white-labeled (sold under multiple brand names) or built through contract manufacturing arrangements; details are not always public.

How OEM relationships impact quality, support, and service

OEM relationships can affect:

• Spare parts availability: proprietary parts may require OEM channels and specific lead times.
• Service coverage: local service capability may depend on authorized networks rather than the brand alone.
• Software and diagnostics: some devices require manufacturer tools for troubleshooting, limiting third-party repair options.
• Traceability and field actions: clear documentation on model variants and serial numbers supports efficient safety notifications and repairs.

For hospital operations leaders, the practical question is: who will provide training, parts, turnaround time, and accountability over the device’s lifecycle?

Facilities often prioritize serviceability and local repair options to reduce downtime. Home care demand and hospital contingency planning can both contribute to concentrator utilization depending on local oxygen infrastructure.

Turkey

Turkey’s position as a regional healthcare hub and its manufacturing and distribution capabilities can support a broad availability of oxygen-related medical equipment. Concentrators may be used across home care and facility settings, with procurement influenced by service network strength and standardization needs across hospital groups. Urban-rural differences can affect access to maintenance and spare parts.

Germany

Germany’s market is supported by strong medical device regulation, robust hospital engineering functions, and established home oxygen services. While hospitals often rely on piped oxygen, concentrators remain relevant in home care and specific clinical workflows. Procurement typically emphasizes compliance documentation, service contracts, and lifecycle management through structured biomedical engineering programs.

Thailand

Thailand’s healthcare system includes both high-capability urban hospitals and rural service delivery challenges, supporting varied use of concentrators. Medical tourism and private sector investment can drive demand for reliable, well-supported equipment in urban centers. In rural areas, procurement may focus on ease of use, maintenance access, and resilience planning for power and logistics constraints.

Key Takeaways and Practical Checklist for Oxygen concentrator

• Treat Oxygen concentrator use as part of an oxygen therapy plan under local clinical protocols.
• Confirm whether the device is continuous-flow or pulse-dose before selecting it for a patient.
• Verify the Oxygen concentrator can meet the required flow and duty cycle per the IFU.
• Place the unit upright with adequate clearance so vents are not blocked.
• Use a grounded outlet and do not operate with a damaged cord or plug.
• Avoid non-approved adapters, improvised connectors, and mismatched accessories.
• Ensure a backup oxygen source is immediately available for failure or transport.
• Check asset tag, PM label, and out-of-service status before bedside use.
• Inspect inlet filters for clogging and confirm required filters are installed.
• Power on and allow the model-specific warm-up/self-test time.
• Confirm flow at the patient end, not only at the flow meter.
• Read the flow meter at eye level and ensure the indicator is stable.
• Remember that flow setting is not the same as FiO₂ and must be clinically correlated.
• Do not assume pulse-dose numeric settings equal L/min across different models.
• Monitor the patient using your facility’s standard oxygenation and observation methods.
• Escalate clinically if the patient deteriorates rather than repeatedly adjusting the device.
• Respond to alarms promptly and do not silence alarms without fixing the cause.
• Keep the device away from open flames, smoking, and high-heat sources.
• Use oxygen safety signage and reinforce no-smoking rules in oxygen-use areas.
• Keep tubing managed to reduce trip hazards and accidental disconnections.
• If humidification is used, assemble the bottle correctly and keep it upright.
• Prevent water from entering the device and manage condensation per policy.
• Stop use and remove from service for burning smell, smoke, sparking, or fluid ingress.
• Use a structured troubleshooting sequence: patient first, then power, then flow path, then alarms.
• Document device ID, settings, and patient response in the clinical record per policy.
• Log recurrent alarms and failures to support preventive maintenance and trend analysis.
• Clean and disinfect high-touch surfaces between patients using approved products and contact times.
• Treat patient tubing and interfaces as single-patient items unless validated reprocessing exists.
• Align cleaning steps with the manufacturer IFU and infection prevention policy.
• Ensure biomedical engineering has a defined verification method for oxygen concentration performance.
• Track hours of use when available to plan filter changes and service intervals.
• Confirm parts availability, service turnaround time, and warranty process before purchase.
• Evaluate total cost of ownership, including consumables, electricity, and downtime risk.
• Standardize models where possible to reduce training burden and accessory complexity.
• Train staff on model-specific alarms, indicators, and pulse-dose behavior where relevant.
• Include concentrators in fire safety drills and oxygen incident response training.
• Plan for power interruptions with approved backup power solutions and clear escalation steps.
• Establish a quarantine/tagging process for suspected faulty devices to prevent reuse.
• Engage procurement, biomedical engineering, clinicians, and infection prevention in device selection.
• Review incident reports and near misses to improve concentrator workflows and reliability.
