Titration & flow stability

Understanding
the home oxygen setup

Home oxygen is not a plug-and-forget appliance. Delivery efficacy depends on 5 interdependent clinical, mechanical, and architectural parameters.

5-Point diagnostic matrix

Metric 01

Flow requirement (1–5+ LPM)

Validating prescribed Litres Per Minute against actual device output. We differentiate resting flow stability from exertional demands and shallow nocturnal hypoventilation titration.

Continuous vs. Pulse Dose Check

Metric 02

Hours of use

Distinguishing intermittent palliative relief (1–3h) from continuous therapy (16–24h/day). Long-cycleduty puts severe continuous thermal strain oncompressor piston seals and sieve zeolite.

Thermal dissipation validation

Critical acuity

Interruption sensivity

Evaluating the immediate clinical risk if power drops or an internal sieve bed saturates. For high- acuity patients, unbuffered desaturation occurs within 3–8 minutes of flow cessation.

Emergency cylinder need index

Metric 04

Care giver support

Empowering family members and domestichelpers: recognizing amber purity indicators,routine daily distilled water replenishment, andswitching cleanly to high-pressure cylinderregulators.

Guidance sheets

Metric 05

Home leyout and clearance

Machine ventilation cannot overheat. Calculating maximum tubing run radii (up to 15m anti- crush line) without backpressure drop, while guaranteeing fall-hazard free routes from bed to bathroom.

Clinical test: >90% O₂

Device capacity and oxygen purity

Verifying that output volume matches prescription without drop-off under load. Ultrasonic purity analyzer checks output across calibrated 1 to 5 LPM increments.

Safety buffer: 30cm

Placement, ventilation and electrical load

Ensuring 30cm unobstructed air intake clearance away from curtains, direct sun, or bed corners. Direct wall-plug connection to prevent extension cord voltage sags.

Lumen and softness

Accessories, consumables and humidification

Inspection of nasal prong flexibility to avoid septal ulceration, high-flow crush-resistant kink-free supply lines, inline water condensation traps, and sterile distilled water bubble jars.

Pre-Flight check

Daily operating routine and audible alarms

Testing the battery-backed power failure alarm, high-pressure relief valve, and visual flow meter balls. Logging starting hour meter readings to predict filter maintenance cycles.

Triage prepared

Caregiver readiness and emergency protocol

Physical demonstration of switching to backup medical oxygen cylinders, checking regulator psi pressure, and reaching the rfreshco 24-hour clinical escalation desk.

Continuity matters:
planning for the unexpected

Medical concentrators are complex electromechanical machines that run continuously for months.The critical clinical difference is what happens when a machine alarms at 2:00 AM.

Never depand on
a single point of failure

Most home providers drop off a single unit and instruct families to call an officehotline if anything goes wrong. In contrast, our clinical protocol integratesphysical cylinder reserves and rapid dispatch.

Keep the equipment
running safely

Oxygen delivery lines and filters harbor bacteria and accumulate ambient Singaporehumidity. Follow our structured consumable replacement schedule.

Every 2-4 weeks

Nasal cannulas and soft prongs

Pliable soft prongs harden with skin oils, riskingmucosal ulceration and bacterial colonization. Replace regularly to maintain comfort andhygiene.

Rule: Never wash cannulas in harsh detergents or bleach.

Every 2-3 months

Extension tubing and water traps

Inspect 7.5m / 15m anti-kink lines forcondensation accumulation and micro-cracking. Install inline water traps to capture tropicalhumidity condensation.

Rule: Replace tubing immediately if discolorationappears.

Daily refill / weekly descale

Bubble humidifier bottle

Empty and refill daily strictly with sterile distilledor cooled boiled water. Never use mineral water. Descale bottle diffuser ports weekly with mildvinegar.

Rule: Replace complete bottle assembly every 6 months.

Weekly wash / 6-mo hepa

Coarse foam and internal hepa

Wash external black sponge intake filters weeklyunder running tap and air dry completely.Internal sub-micron HEPA filters require 6-monthclinical exchange.

Rule: Running a machine with damp foam ruinscompressor valves.

When replacement
may be appropriate

We are dedicated to maintaining your existing equipment whenever viable. However, clinical and mechanical realities make machine replacement the safest choice in specific scenarios.

Repeated fault alarms and heat warnings

Frequent O₂ purity drop warnings (amber/red indicator lights) or thermal cutoff shutdowns indicating severe internal cooling breakdown or valve leakage.

Ageing zeolite beds and exceeded hour ratings

When concentrators exceed 15,000–20,000 operational hours and the molecular sieve beds saturate, rebuilding internal columns may exceed the commercial value of a new whisper-quiet unit.

Legacy parts discontinuation

Legacy models whose manufacturers have ceased production of certified intake valves, mainboards, or manifold seals cannot be reliably maintained to clinical tolerances.

Changing prescription requirements

If your pulmonologist escalates your flow from 2 LPM to 5+ LPM, or requires night-time continuous delivery where a portable pulse-dose unit is currently deployed.

Our experience guarantee

Zero pressure, evidence-based assessment

rfreshco never promotes premature replacement. If yourexisting concentrator can be refreshed with a simplevalve service and filter overhaul, that is precisely whatour technicians will recommend.

"We measure purity with calibrated clinical sensors. Thetelemetry data guides the pathway—not a sales quota."

Servicing, loaner and turnaround

Oxygen therapy cannot pause for workshop maintenance.
Our structured 4-stage protocol ensures continuous therapeutic delivery throughout the diagnostic lifecycle.

Calibrated diagnostic precision

Every machine serviced or deployed under loaner coverage undergoes ultrasonic O₂ purity analysis, particulate filtration renewal, and pressure transducer testing calibrated to Singapore MOH medical device safety standards.
