To use an oxygen concentrator safely at home, place it in a well-ventilated room away from walls and flammable materials, set the flow rate dial to the exact LPM your doctor prescribed, connect the nasal cannula, and ensure uninterrupted power supply. Never smoke or use open flames near an operating oxygen concentrator.
What is an Oxygen Concentrator?
An oxygen concentrator is a medical device that filters nitrogen from room air to deliver concentrated oxygen (87–96% purity) directly to a patient. Unlike oxygen cylinders, concentrators do not need refilling — they run continuously on electricity and produce oxygen on demand, making them ideal for long-term home use.
Who Needs an Oxygen Concentrator at Home?
- COPD (chronic obstructive pulmonary disease) patients with low resting SpO₂
- COVID-19 recovery patients with persistent low oxygen levels
- Pneumonia patients discharged from hospital on supplemental oxygen
- Heart failure patients with hypoxemia
- Post-surgery patients requiring short-term oxygen support
- Sleep apnea patients with nocturnal desaturations
Step-by-Step: How to Set Up a Home Oxygen Concentrator
- Place the concentrator at least 30 cm from all walls and furniture to allow free airflow to the intake vents.
- Keep it away from curtains, bedding, upholstered furniture, and any flammable materials.
- Plug directly into a wall socket — never use an extension cord or multi-plug board.
- Attach the oxygen tubing securely to the outlet port on the concentrator.
- Set the flow rate dial to the exact LPM (litres per minute) prescribed by your doctor — do not adjust without medical advice.
- Connect the nasal cannula or oxygen mask to the free end of the tubing.
- Switch on the device — it will begin delivering oxygen within 5–10 minutes of starting.
- Check the indicator panel for any alarms or warning lights before leaving the patient unattended.
Safety Rules — What You Must Never Do
- Never smoke in the same room as an operating oxygen concentrator — oxygen enriches the air and makes fires burn faster.
- Never use near a gas stove, candles, incense sticks, or any open flame.
- Never cover or enclose the concentrator in a cupboard or curtained area.
- Never increase the flow rate beyond your doctor's prescription.
- Never use an extension cord — plug only into a dedicated wall socket.
- Never attempt to repair the device yourself — call Medrent at 9818601212.
How to Clean and Maintain a Rented Oxygen Concentrator
| Task | Frequency | How to Do It |
|---|---|---|
| Wipe exterior | Daily | Clean damp cloth — do not use alcohol or bleach on casing |
| Clean nasal cannula | Daily | Wash with mild soap and water, rinse, air dry completely |
| Check air intake filter | Every 2 weeks | Remove, rinse under water, let dry fully before replacing |
| Check oxygen tubing | Weekly | Inspect for kinks, cracks, or blockages — replace if damaged |
| Full equipment service | Monthly | Contact Medrent — do not service yourself |
What Flow Rate Do I Need?
Your doctor prescribes the flow rate in LPM (litres per minute) based on your condition and SpO₂ readings. Common prescriptions: 1–2 LPM for mild COPD or sleep support, 2–4 LPM for moderate respiratory conditions, 4–6 LPM for severe or acute cases. A 5 LPM concentrator covers most home patients. For prescribed rates above 5 LPM, a 10 LPM machine is needed. Both are available on rent from Medrent.
Frequently Asked Questions
How long can an oxygen concentrator run continuously?
Most home oxygen concentrators are designed to run 24 hours a day, 7 days a week. For non-critical patients, giving the machine a 20–30 minute rest every 8–10 hours can extend its life — but only if your doctor confirms you can safely pause oxygen during that period.
What does it mean if my oxygen concentrator alarm goes off?
An alarm typically indicates low oxygen purity (dirty filter), blocked airflow (device covered or vent obstructed), high internal temperature, or a power issue. Check the filter and ventilation immediately. If the alarm continues, call Medrent at 9818601212 — do not switch off without ensuring the patient has an alternative oxygen source.
Can I use an oxygen concentrator during a power cut?
No — oxygen concentrators require continuous electricity to function. If you are on prescribed continuous oxygen therapy, you must have an oxygen cylinder as a power-cut backup. Discuss your backup plan with your doctor before discharge.
What SpO₂ level requires supplemental oxygen at home?
Doctors typically prescribe home oxygen when resting SpO₂ consistently falls below 88–90%. Always follow your doctor's specific prescription — never self-prescribe supplemental oxygen based on pulse oximeter readings alone.
What is the difference between a 5 LPM and 10 LPM oxygen concentrator?
A 5 LPM concentrator delivers up to 5 litres of oxygen per minute, sufficient for most home patients on standard prescriptions. A 10 LPM concentrator is required for patients prescribed high flow rates, or when two patients share one machine. Both are available on rent from Medrent.
