What is High flow nasal cannula system: Uses, Safety, Operation, and top Manufacturers!

H2: Introduction

High flow nasal cannula system is a respiratory support medical device that delivers warmed, humidified gas (oxygen alone or an oxygen/air blend) through wide-bore nasal cannulae at flow rates higher than conventional oxygen therapy. In many hospitals, it sits between standard nasal cannula/face mask therapy and more invasive forms of ventilatory support, and it is used across emergency, perioperative, inpatient, and intensive care workflows.

For clinicians, High flow nasal cannula system can improve patient tolerance, help deliver more consistent inspired oxygen, and support escalation or de-escalation pathways when managed with clear monitoring and safety criteria. For hospital administrators and procurement teams, it also raises practical questions: oxygen supply capacity, consumables, staff training, infection control, maintenance, and service coverage. For biomedical engineers, it is a piece of hospital equipment where reliability, preventive maintenance, calibration (where applicable), and device integration affect uptime and safety.

This article explains what High flow nasal cannula system is, when it is commonly used (and when it may not be suitable), what you need before starting, basic operation, patient safety practices, output interpretation, troubleshooting, cleaning principles, and a globally oriented market overview to support planning and procurement.

H2: What is High flow nasal cannula system and why do we use it?

Definition and purpose

High flow nasal cannula system is clinical device designed to deliver high-flow, heated, humidified respiratory gas via nasal prongs. Unlike low-flow nasal cannulae that deliver oxygen at relatively low flow rates, High flow nasal cannula system can deliver flows intended to better match or exceed a patient’s inspiratory demand, which can help reduce room-air entrainment and support more stable oxygen delivery.

A typical High flow nasal cannula system includes:

A flow source (flow generator or high-capacity flowmeter)
An oxygen/air blender (in many configurations) to set the fraction of inspired oxygen (FiO₂)
A heated humidifier and humidification chamber
A heated breathing circuit to reduce condensation and maintain temperature
A nasal cannula interface in multiple sizes
Alarm and monitoring functions (varies by manufacturer)

It is important to recognize what it is not: High flow nasal cannula system is generally not a ventilator. It does not provide controlled breaths, does not measure tidal volume, and does not guarantee a set airway pressure. Any positive airway pressure effect is typically variable and dependent on factors such as flow, mouth position, and cannula fit (varies by manufacturer and patient conditions).

Common clinical settings

High flow nasal cannula system is widely seen in:

Emergency departments (early respiratory support and stabilization)
Intensive care units (ICUs) and high-dependency/step-down areas
Post-anesthesia care units (PACU) and perioperative areas
General wards with enhanced monitoring capability (where allowed by policy)
Pediatric and neonatal care environments (with appropriately sized interfaces and protocols)

Use location is often governed by local policy because staffing ratios, monitoring availability, and escalation pathways strongly influence safety.

Key benefits in patient care and workflow

From an operational standpoint, High flow nasal cannula system is used because it can offer a combination of patient comfort and performance features that conventional oxygen therapy may not provide.

Commonly described benefits include:

Heated humidification that can reduce mucosal dryness and improve comfort compared with cold, dry oxygen at higher flows
Higher total flow that can support more consistent oxygen delivery in patients with high inspiratory demand
Nasal interface that may be better tolerated than tight-fitting masks for some patients, allowing speaking and oral intake when appropriate per policy
Workflow flexibility for escalation and weaning pathways, especially in units that aim to standardize oxygen therapy escalation steps
Improved secretion management in some care contexts due to humidification (clinical applicability varies)

For hospital administrators, the device’s value often depends on protocols and system design: adequate monitoring, clear failure criteria, rapid access to escalation, and reliable oxygen and power infrastructure.

H2: When should I use High flow nasal cannula system (and when should I not)?

Appropriate use cases (general, non-prescriptive)

High flow nasal cannula system is commonly used in hospitals for patients who need more respiratory support than conventional oxygen therapy can provide but who may not immediately require invasive ventilation. Common scenarios reported in clinical practice include:

Acute hypoxemic respiratory failure (cause-dependent and protocol-dependent)
Pneumonia and other acute respiratory infections where oxygen needs are high
Post-extubation support or step-down support after ventilation (per protocol)
Pre-oxygenation and peri-procedural support in monitored settings (facility-dependent)
Selected pediatric respiratory conditions (using pediatric-specific guidance and interfaces)

The decision to start High flow nasal cannula system is a clinical one and should be made within facility protocols, with defined monitoring and escalation pathways.

Situations where it may not be suitable

High flow nasal cannula system may be inappropriate or insufficient in situations where a patient requires immediate airway protection or definitive ventilatory support. Examples of circumstances where clinicians often consider alternatives include:

Rapidly deteriorating respiratory status where delays could be harmful
Situations needing definitive ventilatory support rather than oxygen delivery alone
Inability to protect the airway or high aspiration risk (context-specific)
Upper airway obstruction where the mechanism of support is inadequate
Severe facial or nasal trauma, recent nasal surgery, or conditions preventing safe nasal interface placement (case-by-case)
Poor tolerance of nasal prongs despite optimization attempts

These are general considerations; suitability depends on patient assessment, facility capability, and local policy.

Safety cautions and contraindications (general)

Because High flow nasal cannula system is high-flow oxygen-capable hospital equipment, common safety cautions include:

Risk of delayed escalation if the patient is not closely monitored or if escalation criteria are unclear
Oxygen fire risk in high-FiO₂ environments (especially around ignition sources)
Nasal mucosal injury or pressure injury from cannula fit, securement, or prolonged use
Dryness or discomfort if humidification is not functioning as intended
Condensation (“rainout”) management issues that can affect comfort and performance
Power dependency (heated humidifiers generally require mains power; battery behavior varies by manufacturer)

Always rely on the manufacturer’s instructions for use (IFU), the facility’s oxygen therapy policy, and competency-based practice expectations.

H2: What do I need before starting?

Required setup, environment, and accessories

Before initiating High flow nasal cannula system, facilities typically ensure the following infrastructure and accessories are available and verified:

Environment and utilities

Reliable electrical power supply (and backup arrangements according to local policy)
Adequate oxygen source (wall supply, cylinders, liquid oxygen, or concentrator-based systems)
Adequate medical air supply if the device uses an oxygen/air blender (varies by configuration)
Appropriate monitoring capability for the care area (pulse oximetry minimum; other monitoring per policy)
Suction availability for secretion management as needed

Core components and consumables

Flow generator or high-capacity flow delivery module
Blender or mixing module (if present)
Heated humidifier base
Humidification chamber (single-use or reusable; varies by manufacturer)
Heated circuit/tubing and temperature probe(s)
Nasal cannulae in appropriate sizes (adult, pediatric, neonatal as applicable)
Water for humidification (type specified by IFU; commonly sterile water)
Filters if required by the system design (varies by manufacturer)
Securement accessories (head straps, clips) as approved by policy

Operational considerations

Space for device placement that avoids trip hazards and allows staff access
A plan for safe cylinder management if portable oxygen is used
A contingency plan for power failure, oxygen supply interruption, and escalation of care

Training and competency expectations

High flow nasal cannula system is often perceived as simpler than ventilators, but safe use still requires structured training. Typical competency elements include:

Device setup and pre-use checks
Understanding of flow, FiO₂, and temperature controls (conceptually and practically)
Cannula sizing and placement principles
Alarm recognition and response
Patient monitoring requirements and documentation
Escalation pathways and “failure” recognition per facility protocol
Infection prevention practices, including handling humidification water and condensate

For administrators, training should be tracked (e.g., competency sign-offs) and updated when models, accessories, or protocols change.

Pre-use checks and documentation

A practical pre-use check (adapt to IFU and local policy) often includes:

Confirm the device is within preventive maintenance (PM) date and has no outstanding service notices
Visual inspection: casing, cables, plugs, connectors, tubing ports, and cannula packaging integrity
Verify correct accessories are available and compatible (do not mix circuits/cannulae across systems unless explicitly approved by the manufacturer)
Confirm gas supply availability and adequate pressure (pipeline/cylinder status)
Verify water chamber is correctly seated and filled per IFU (do not overfill)
Ensure temperature probes and heated-wire circuits are correctly connected
Power on self-test and alarm check (where available)
Confirm oxygen concentration measurement method (if built-in) is functional and calibrated if required (varies by manufacturer)
Document baseline patient observations and the initial device settings per protocol

Good documentation supports continuity of care, incident review, and asset performance monitoring.

H2: How do I use it correctly (basic operation)?

Basic step-by-step workflow (general)

The exact workflow varies by manufacturer, but most High flow nasal cannula system setups follow a consistent pattern.

Prepare the area
Ensure monitoring is available, suction is accessible, and the device can be positioned safely with clear staff access.
Hand hygiene and PPE
Follow facility infection prevention requirements.
Assemble the system
Install the humidifier chamber, connect the heated circuit, and connect temperature probes as required. Ensure the circuit is routed to minimize kinks and trip hazards.
Connect gas supplies
Connect oxygen (and medical air if required). Verify supply pressures/availability. If using cylinders, confirm regulators are appropriate for the required flow and that a safe cylinder handling process is in place.
Fill humidification chamber with the correct water type
Use the water specified by the IFU (commonly sterile water). Avoid topping up in a way that risks contamination; replacement intervals vary by manufacturer and facility policy.
Power on and allow warm-up
Heated humidification typically requires a warm-up period to reach target temperature and humidity.
Select the correct nasal cannula size and fit
Cannula prongs should typically not occlude the nares completely. Secure the cannula to minimize pressure injury on the nose and ears.
Set initial parameters per protocol
Set flow, FiO₂, and temperature. Ensure the values match the order or protocol and are appropriate for the patient population (adult/pediatric/neonatal).
Apply the cannula and confirm patient comfort
Confirm the patient can tolerate the flow and that the cannula remains stable with head movement.
Confirm device function
Check for expected flow, correct temperature trend, absence of major leaks/disconnections, and any immediate alarms.
Ongoing monitoring and documentation
Record settings and patient response at intervals defined by policy, and reassess frequently for improvement or deterioration.

Setup, calibration, and checks (where relevant)

Not every High flow nasal cannula system requires routine user calibration, but some configurations include oxygen analyzers or blenders that require periodic verification.

Common calibration-related considerations include:

Oxygen analyzer verification: Some systems measure oxygen concentration; accuracy checks may be part of biomedical engineering PM rather than bedside workflow.
Blender accuracy: If a blender is used, its accuracy and alarm function are typically verified during PM and after service.
Temperature control checks: The device may monitor circuit temperature and heater performance; alarms may indicate probe issues or heater faults.

Calibration schedules and responsibilities vary by manufacturer, regulatory requirements, and hospital policy.

Typical settings and what they generally mean

Facilities typically define starting settings and titration steps in protocols. The following describes what settings represent in general terms (not prescribing specific clinical values):

Flow (L/min)
Higher flow can better meet inspiratory demand and may reduce entrainment of room air. Adult flows are often in the tens of liters per minute; pediatric/neonatal flows are typically lower. Maximum flow varies by manufacturer.
FiO₂ (%)
FiO₂ is the set oxygen concentration of delivered gas when a blender is used. Actual inspired oxygen can differ from the set value depending on patient breathing pattern, mouth position, interface fit, and leaks.
Temperature (°C)
Temperature is used to support humidification and comfort. Many systems offer multiple temperature targets; exact ranges and labels vary by manufacturer.

Operationally, treat these settings as part of a monitored therapy: any change should be documented and followed by reassessment consistent with policy.

H2: How do I keep the patient safe?

Monitoring practices and escalation readiness

High flow nasal cannula system can be highly effective when paired with consistent monitoring and rapid escalation pathways. Safety-focused monitoring often includes:

Continuous or frequent pulse oximetry per acuity
Regular assessment of respiratory rate, work of breathing, and patient comfort
Heart rate and blood pressure monitoring according to care setting
Level of consciousness and ability to protect the airway (as relevant)
Assessment of secretion burden and ability to clear secretions
Skin and mucosal checks: nares, cheeks, and ears for pressure injury
Consideration of additional monitoring (e.g., blood gases) according to protocol and clinical judgement

A key safety principle is not allowing device familiarity to reduce vigilance. High flow nasal cannula system is supportive hospital equipment; it does not replace clinical assessment.

Alarm handling and human factors

Alarm design and behavior vary by manufacturer, but common issues include disconnection, low flow, high temperature, low water level, or power problems. Practical alarm management includes:

Ensure staff know which alarms are high priority and require immediate action
Confirm alarm volumes are appropriate for the care area (without creating alarm fatigue)
Avoid silencing alarms without resolving the underlying cause
Standardize a quick bedside check sequence (connections → gas supply → water chamber → circuit integrity → cannula position)

Human factors that influence safety:

Tubing management to avoid accidental dislodgement
Clear labeling of oxygen and air connections, especially during transfers
Avoiding circuit tension that pulls on the cannula
Ensuring the device is placed to prevent spills into electrical components
Communicating clearly with patients about what to expect (noise, warmth, flow sensation)

Oxygen safety, fire risk, and facility controls

Because High flow nasal cannula system can deliver high oxygen flows, oxygen safety must be treated as a facility-wide responsibility:

Maintain no-smoking and ignition-source controls in oxygen-enriched environments
Follow safe use policies for alcohol-based products, skin ointments, and petroleum-based materials near oxygen delivery interfaces
Ensure cylinders are stored, transported, and secured correctly
Train staff on emergency response for oxygen-related fire events

Humidification safety: water, condensate, and burns

Heated humidification improves tolerance but introduces specific risks:

Use only the water type specified by the manufacturer IFU
Minimize contamination risk when refilling or replacing chambers (policy-driven)
Manage condensate: keep tubing positioned to prevent pooled water from reaching the patient
Be alert to temperature alarms or patient complaints of excessive heat
Inspect for “rainout” that can increase noise, resistance, or discomfort

Equity and resource considerations

In low-resource settings, the safety profile can be strongly influenced by infrastructure:

Oxygen supply stability may limit safe, sustained high-flow use
Power instability can disrupt humidification and alarms
Consumable availability may drive unsafe reuse practices if governance is weak

Administrators can reduce risk by aligning device deployment with realistic infrastructure capacity and by budgeting for consumables and maintenance as part of total cost of ownership.

H2: How do I interpret the output?

Types of outputs and readings

High flow nasal cannula system typically provides device-level information such as:

Set flow rate
Set FiO₂ (if blender-based)
Set temperature and warm-up status
Alarm states (e.g., disconnection, temperature out of range, low water, occlusion)

Some systems display measured values (e.g., delivered oxygen concentration) or offer trend data. The availability and accuracy of these features varies by manufacturer and configuration.

How clinicians typically interpret them (general)

Clinicians generally interpret High flow nasal cannula system outputs in combination with patient monitoring:

Whether oxygen saturation improves or stabilizes with therapy
Whether work of breathing appears reduced
Whether the patient can tolerate the interface and flow
Whether device settings are stable and alarms are absent or explainable

The key point: the device’s display shows what the device is set to do, not necessarily what the patient is physiologically achieving. Patient response must be monitored using clinical observation and standard monitoring equipment.

Common pitfalls and limitations

Common interpretation pitfalls include:

Assuming the set FiO₂ equals the patient’s inspired oxygen under all circumstances
Confusing high flow delivery with ventilatory support (it does not provide controlled ventilation)
Overlooking cannula displacement, mouth breathing, or leaks that reduce effectiveness
Ignoring the impact of inadequate humidification (dry gas reduces tolerance and may increase complications)
Misattributing alarms to patient failure when the cause is equipment setup (or vice versa)

Limitations to keep in mind:

Positive airway pressure effects are variable and not tightly controlled
Flow and FiO₂ accuracy may depend on gas source stability and device condition
Integration into hospital monitoring/EMR systems varies by manufacturer and is not publicly stated for all models

H2: What if something goes wrong?

A practical troubleshooting checklist

When there is a problem, separate patient deterioration from equipment malfunction as quickly as possible. A structured checklist can reduce delays.

1) First: assess the patient (within scope and policy)

Check consciousness, visible distress, and overall stability
Confirm the cannula is in place and the patient is tolerating therapy
Ensure monitoring is functioning and readings are plausible
Escalate per facility rapid response policy if there are signs of deterioration

2) Then: check the device and setup

Power: device on, no loose plug, no liquid spill, no overheating
Gas supply: pipeline pressure available, cylinders not empty, regulators functioning
Connections: oxygen/air lines fully seated, circuit properly attached, no kinks
Humidifier: chamber seated correctly, water at correct level, heater functioning
Cannula: correct size, not blocked, not twisted, securement not causing occlusion
Condensate: pooled water not obstructing flow; tubing positioned appropriately

3) If alarms persist

Follow the manufacturer alarm guide (priority, likely cause, corrective action)
Replace single-use components if contamination, blockage, or damage is suspected
Swap to a backup unit if available and permitted by policy

Common issues and practical responses (non-brand-specific)

Low flow / no flow alarm: confirm gas source, check kinks/occlusion, confirm cannula not blocked, verify settings not inadvertently changed.
FiO₂ not achieved: confirm oxygen source pressure, blender function, and that the correct gas sources are connected; consider analyzer verification per policy.
Temperature out of range: confirm probes are connected and correctly placed, check chamber seating, and allow warm-up; stop use if overheating is suspected.
Excessive rainout: check temperature setting, room temperature, circuit positioning, and ensure heated-wire function is active if applicable.
Patient discomfort: reassess cannula size/position and humidification; confirm temperature and flow are within protocol; consider alternative interface per clinician judgement.

When to stop use (general principles)

Stopping therapy may be appropriate when:

There is suspected device-related harm risk (electrical hazard, smoke/burning smell, uncontrolled overheating, fluid ingress)
The system cannot deliver therapy reliably despite troubleshooting
The patient’s condition is worsening and escalation is required per protocol

Decisions about changing respiratory support should follow clinical leadership and facility escalation pathways.

When to escalate to biomedical engineering or the manufacturer

Escalate to biomedical engineering when:

A device fails self-tests, shows repeated unexplained alarms, or exhibits inconsistent performance
There is suspected blender/analyzer inaccuracy requiring verification
Parts are damaged, missing, or repeatedly failing
Preventive maintenance is overdue or service history suggests a pattern

Escalate to the manufacturer (often via authorized service channels) when:

A suspected device defect persists after standard troubleshooting
There are software faults, recurring error codes, or safety-related concerns
You need clarification on compatibility of consumables/accessories
Service manuals, parts, or recall/field safety notice information is required (availability varies)

From a governance perspective, document incidents, quarantine suspect equipment, and preserve disposables if needed for investigation, consistent with policy.

H2: Infection control and cleaning of High flow nasal cannula system

Cleaning principles for this medical equipment

High flow nasal cannula system combines humidification, heated circuits, and patient-contact interfaces, which increases infection prevention complexity. Infection control programs typically focus on:

Single-patient use components (nasal cannula, patient circuit, humidification chamber in many models)
Preventing water contamination and biofilm formation
Correct disinfection of reusable external surfaces and non-disposable components
Reducing cross-contamination during setup and teardown

Always follow the manufacturer IFU and local infection prevention policy, especially regarding what is disposable versus reprocessable.

Disinfection vs. sterilization (general)

Cleaning removes visible soil and reduces bioburden; it is usually required before disinfection.
Disinfection reduces microorganisms to an acceptable level; it may be low-level or high-level depending on risk classification and local policy.
Sterilization eliminates all microbial life and is typically reserved for instruments or components requiring sterile processing.

For High flow nasal cannula system, many patient-contact components are designed as single-use consumables. Reprocessing single-use items should only occur if explicitly allowed by applicable regulations, the manufacturer, and facility governance (often not allowed).

High-touch points to prioritize

Even when patient circuits are disposable, external contamination can occur. High-touch points commonly include:

Touchscreen, buttons, rotary knobs
Power switch and power cord
Gas inlet connectors and strain relief areas
Humidifier exterior surfaces and chamber latch points
Pole/stand handles and cable hooks
Areas where staff adjust settings during care

Example cleaning workflow (non-brand-specific)

Adapt the steps below to IFU and local policy:

Perform hand hygiene and don appropriate PPE.
Turn off the device and disconnect from the patient safely per protocol.
Dispose of single-use components (nasal cannula, circuit, chamber) in appropriate waste streams.
Cap or protect gas ports if recommended to prevent fluid ingress during cleaning.
Clean exterior surfaces with an approved detergent/disinfectant process (follow contact time).
Pay special attention to controls, connectors, and frequently handled surfaces.
Allow surfaces to dry fully before reconnecting power or storing.
Replace filters if the IFU specifies routine filter changes after use or at scheduled intervals (varies by manufacturer).
Document cleaning completion and any issues noted (cracks, loose connectors, alarm faults).
Store the device in a clean area to prevent re-contamination.

Water handling and condensate governance

Water and condensate are frequent weak points in real-world practice:

Use the correct water source and container handling practice to reduce contamination risk
Avoid topping up in a way that increases handling events (policy-dependent)
Position tubing to reduce condensate reaching the patient interface
Do not drain condensate toward the patient; follow facility guidance for safe removal if needed

In procurement and operations, standardizing consumables and workflows often improves infection prevention consistency.

H2: Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

In healthcare technology management and procurement, the terms matter:

A manufacturer is typically the company that markets the medical device under its brand and holds regulatory responsibility for the finished product in specific jurisdictions.
An OEM is a company that manufactures components or complete devices that may be sold under another company’s brand or incorporated into a larger system.

OEM relationships can affect:

Quality and traceability: clear documentation supports recalls and field safety actions.
Serviceability: parts availability, service manuals, and authorized service networks vary.
Support continuity: rebranding, distribution changes, or OEM transitions can complicate long-term support.
Consumable compatibility: proprietary circuits/cannulae can lock in supply chains; compatibility rules vary by manufacturer.

For High flow nasal cannula system procurement, confirm authorized supply, warranty terms, service coverage, and consumables strategy (including backorder and substitution policies).

H2: Key Takeaways and Practical Checklist for High flow nasal cannula system

Treat High flow nasal cannula system as supportive respiratory hospital equipment, not a ventilator replacement.
Align deployment locations (ED/ICU/ward) with staffing ratios and monitoring capability.
Standardize clinical protocols for initiation, monitoring frequency, and escalation criteria.
Confirm oxygen source capacity before scaling high-flow therapy across units.
Include oxygen consumption impact in operational planning and surge preparedness.
Verify whether the system requires medical air in addition to oxygen (varies by configuration).
Ensure power backup planning, especially where heated humidification is essential for tolerance.
Use only manufacturer-approved circuits, chambers, and cannulae to reduce performance and safety variability.
Keep a documented compatibility list to prevent inadvertent cross-brand consumable use.
Implement competency-based training for setup, alarms, and troubleshooting.
Require staff to demonstrate correct cannula sizing and securement techniques.
Confirm humidifier chamber seating and correct water fill level before patient connection.
Use the water type specified in the IFU and control refilling practices to reduce contamination risk.
Position tubing to minimize rainout and prevent pooled condensate reaching the patient.
Include routine skin and mucosal checks in nursing documentation to prevent pressure injury.
Treat recurrent patient discomfort as a safety signal and reassess interface, humidity, and securement.
Manage alarm fatigue by defining which alarms demand immediate bedside response.
Never silence alarms without resolving the underlying cause and documenting actions.
Use a simple “patient first, device second” troubleshooting sequence during alarms.
Keep a ready-to-deploy backup unit or alternate oxygen delivery method per unit policy.
Document initial settings and every change in flow, FiO₂, and temperature with time stamps.
Remind teams that set FiO₂ may not equal inspired oxygen under all breathing patterns.
Confirm gas supply connections during transfers to prevent accidental air/oxygen swap errors.
Maintain strict oxygen fire safety controls in high-FiO₂ environments.
Enforce cylinder handling and securing practices where portable oxygen is used.
Quarantine devices with suspected electrical faults, overheating, or fluid ingress immediately.
Escalate repeated unexplained alarms to biomedical engineering rather than “work around” behavior.
Track preventive maintenance dates and standardize PM intervals per manufacturer guidance.
Audit consumable stock levels (cannulae, circuits, chambers) to prevent therapy interruption.
Build total cost of ownership models that include consumables, service, and training time.
Prefer vendors with proven local service coverage and clear spare-parts pathways.
Require traceability for consumables to support recalls and incident investigations.
Separate single-use patient-contact components from reusable device surfaces in cleaning SOPs.
Focus cleaning on high-touch points like screens, knobs, gas connectors, and stand handles.
Validate disinfectant compatibility with plastics and coatings to avoid long-term damage.
Do not reprocess single-use items unless explicitly allowed by regulation and the manufacturer.
Incorporate infection prevention review into device rollout and unit onboarding.
Use incident reporting to capture near-misses such as misconnections, water contamination, and dislodgement.
Include HFNC-specific checks in shift handovers (settings, comfort, skin, condensate, alarms).
Plan for rural and low-resource constraints by matching devices to realistic oxygen and power infrastructure.
Evaluate whether the device provides measured FiO₂ or only set FiO₂ (varies by manufacturer).
Keep quick-reference guides at the bedside for alarms and setup steps to reduce variation.
Confirm warranty terms, authorized service arrangements, and software update pathways during procurement.
Review local regulatory requirements for medical equipment import, registration, and servicing.
Establish clear criteria for when to switch therapies to avoid delayed escalation in deteriorating patients.
