This is general information, not medical advice. Home oxygen therapy must be prescribed by a doctor. Never start, stop, or adjust the flow rate on your own. Always follow your doctor's specific prescription for litres per minute and hours of use. If you are unsure about anything, ask your treating physician.
🩹 Who needs home oxygen?
Your doctor may prescribe home oxygen therapy if your blood oxygen levels are consistently low at rest. The most common conditions include:
Lung conditions
- COPD (chronic obstructive pulmonary disease) — the most common reason
- Interstitial lung disease / pulmonary fibrosis
- Bronchiectasis
- Post-COVID complications (persistent hypoxaemia)
- Pulmonary hypertension
Other conditions
- Post-ICU recovery — stepping down from hospital
- Advanced cardiac failure
- Tracheostomy patients transitioning home
- Palliative care — comfort at end of life
📈 Key threshold
SpO2 ≤ 88% or PaO2 ≤ 55 mmHg at rest are the standard clinical thresholds for prescribing long-term oxygen therapy (LTOT). Your doctor may prescribe oxygen at higher levels if you have specific complications such as pulmonary hypertension or cor pulmonale.

⚠️ Never self-prescribe or self-adjust oxygen.
Too much oxygen can be as dangerous as too little — especially in COPD, where excess oxygen can suppress the breathing drive. Always follow your doctor's prescribed flow rate (litres per minute) and duration (hours per day).
🩹 Equipment: Concentrator vs Cylinder
Two main options are available for home oxygen in India. Your doctor or discharge team will advise which is appropriate — this comparison helps you understand the practical differences.
🏭 Oxygen Concentrator
Extracts oxygen from room air electrically — no refills needed
| Feature | Details |
|---|
| 5L models (most home use) | ₹25,000–60,000 to buy |
| 10L models (higher flow) | ₹60,000–1,20,000 to buy |
| Rental | ₹3,500–6,500/month (varies by capacity) |
| Electricity | 300–600 watts (like a large fan + fridge) |
| Noise | Quiet hum; manageable in a bedroom |
| Refills | None — runs continuously from room air |
Best for: Long-term use (>6–9 months), continuous overnight oxygen, chronic conditions
🧻 Oxygen Cylinder
Compressed medical-grade oxygen in a steel or aluminium tank
| Feature | Details |
|---|
| Cylinder + regulator | ₹5,000–8,000 (one-time) |
| Refills | ₹150–400 per refill |
| Duration per refill | ~8–12 hours at 2L/min (varies by size) |
| Electricity | None — works during power cuts |
| Portability | Heavy (large); portable sizes available |
Best for: Short-term use, backup during power cuts, travel, emergency reserve
💡 Break-even tip
Renting a concentrator typically costs less than buying for the first 6–9 months. Beyond that, buying saves money long-term. Ask your doctor about expected duration before deciding.

🤔 Rent or Buy? A quick decision guide
🕐 Short-term need (under 6 months)
Rent. Monthly rental (₹3,500–6,500) is cheaper than a full purchase if you need oxygen only during recovery, e.g. post-ICU step-down or post-COVID recovery. Most rental companies include delivery, setup, and basic maintenance.
🕒 Long-term / chronic need (6+ months)
Buy. If your doctor expects you will need oxygen indefinitely (e.g. COPD, pulmonary fibrosis), purchasing a concentrator saves money beyond the 6–9 month mark. Look for models with a 2–3 year warranty and check whether the dealer offers periodic servicing.
💰 Insurance and financial support
Many private health insurance policies in India now cover home oxygen equipment under domiciliary / home healthcare benefits. Check your policy wording or call your insurer. Some policies require a minimum hospitalisation period (e.g. 3 days) before domiciliary benefits kick in.
Ask your hospital discharge team and treating doctor about expected duration — this will help you make the right rent-vs-buy decision and claim the right insurance benefits.
🔥 Safety at home — critical rules
🔥 Fire safety — oxygen supports combustion
Oxygen itself does not burn, but it makes everything around it burn faster and more fiercely. These rules are non-negotiable:
- No smoking within 5 metres of the oxygen equipment or tubing — this includes visitors
- Keep away from open flames — gas stoves, diyas (oil lamps), agarbatti (incense), candles, matchsticks
- No oil-based products near the cannula — petroleum jelly (Vaseline), hair oil, face creams containing oil can ignite in oxygen-enriched air
- Keep at least 5 feet (1.5 m) from heat sources — heaters, radiators, gas geysers, electrical devices that generate heat

🏠 Room setup
- Place the concentrator in a well-ventilated room — not a closed cupboard or corner
- Keep at least 30 cm (1 foot) from walls on all sides for air intake
- Avoid curtains, bedding, or clothes near the machine
- Place on a flat, stable, hard surface — not on a bed or soft carpet
- Keep the tubing clear and untangled to prevent tripping
⚡ Electrical safety (India-specific)
- Use a voltage stabiliser if your area has voltage fluctuations — most concentrators need stable 220V
- Concentrators draw 300–600 watts — check your wiring can handle it, especially in older homes
- Never use extension cords for medical equipment — plug directly into a wall socket
- Keep a backup plan for power cuts (see next section)
- Use an MCB/RCCB-protected circuit where possible for extra safety
⚡ Power backup — critical for India
Power cuts are a reality across India. If someone in your home depends on an oxygen concentrator, a backup plan is not optional — it is essential.
⚠️ Non-negotiable: keep a backup oxygen cylinder
Always have a filled backup oxygen cylinder at home, even if you primarily use a concentrator. This is your immediate fallback during any power cut. Know how to switch to it — practise before you need it.
🔋 UPS / Inverter
- Must be a pure sine wave inverter (not modified sine wave) — concentrators have sensitive compressors
- A 150Ah battery can run a 5L concentrator for approximately 2–3 hours
- Higher-capacity batteries (200Ah+) or dual-battery setups give longer backup
- Check that your inverter's wattage rating exceeds the concentrator's requirement (e.g. 600W+ for a 500W unit)
🌞 Other options
- Portable power stations — 3–10 hours depending on capacity; more expensive but portable
- Solar panels + battery — good long-term option if your home has roof space; requires upfront investment
- Generator — a last resort; noisy and needs fuel; keep it outdoors and well-ventilated
📅 Monthly checklist
Test your backup every month. Switch to the cylinder or inverter for 15 minutes to confirm everything works. Check the cylinder gauge — a half-empty backup is not a backup.
📈 Daily monitoring with a pulse oximeter
A pulse oximeter (₹500–2,000 at any pharmacy or online) clips onto a fingertip and shows two numbers:
SpO2
Blood oxygen saturation (%)
PR
Pulse rate (beats per minute)
🎯 Target SpO2 levels
| Condition | Typical target |
|---|
| COPD (with CO2 retention risk) | 88–92% — higher may suppress breathing drive |
| Other conditions (ILD, cardiac, post-ICU) | 94% or above |
| Your specific target | Whatever your doctor has prescribed |
Source: British Thoracic Society Oxygen Guidelines (2017); GOLD 2024
📝 Keeping a daily log
A simple daily log helps your doctor adjust treatment. Record:
- Time of reading
- SpO2 % and pulse rate
- Flow rate (litres/min as prescribed)
- Symptoms — breathlessness, cough, tiredness
- Activity at the time (resting, walking, after eating)
You can use a simple notebook or a phone notes app. Bring it to every doctor visit.
🤔 Tips for accurate oximeter readings
Pulse oximeters can give wrong readings if:
- Hands are cold — warm them first
- Nail polish or henna (mehendi) on the fingertip — use a clean, bare finger
- Moving your hand during the reading
- Low battery in the oximeter
Wait 10–15 seconds for the number to stabilise before noting it down. Use the same finger each time for consistency.
🚨 When to call your doctor or go to hospital
Seek urgent medical help if any of these occur:
- SpO2 drops below your prescribed target despite oxygen running at the right flow rate
- Increasing breathlessness at rest — not just with activity
- New confusion, unusual drowsiness, or agitation
- Blue or dusky colour in lips, fingertips, or tongue (cyanosis)
- Chest pain or tightness
- Fever with worsening breathing
- Coughing up blood
- Equipment failure and no backup available

🔧 Equipment maintenance
A well-maintained concentrator works better and lasts longer. Most of this you can do yourself:
| Task | How often | Who |
|---|
| Clean / replace the air intake filter | Every 2 weeks | You (rinse with water, air-dry fully) |
| Wipe external surfaces with a damp cloth | Weekly | You |
| Clean the humidifier bottle (if used) | Daily — empty, wash with soap and water, refill with distilled/boiled cooled water | You |
| Replace nasal cannula | Every 2–4 weeks (or sooner if stiff/discoloured) | You |
| Replace tubing | Every 1–3 months | You |
| Professional servicing | Every 6–12 months | Technician / rental company |
💧 Do I need a humidifier bottle?
At flow rates above 3–4 L/min, dry oxygen can irritate the nose and throat. A humidifier bottle (bubble humidifier) adds moisture. Ask your doctor if you need one. If you use one:
- Use only distilled or boiled-and-cooled water — not tap water
- Empty and wash it every day
- Replace the bottle itself every 1–2 months
🏢 Government support and insurance
Financial support for home oxygen in India is limited but improving. Here is what is currently available:
🆚 ADIP Scheme (Assistance to Disabled Persons)
The ADIP scheme, implemented through ALIMCO and government hospitals by the Department of Empowerment of Persons with Disabilities (DEPwD), provides assistive devices to eligible persons with disabilities at subsidised cost or free of charge, based on income criteria.
However: Oxygen concentrators are not specifically listed in the current ADIP scheme catalogue as a standard assistive device. Eligibility and availability can vary — check with your nearest government hospital or ALIMCO centre.

💳 Private health insurance
Many private insurers now include domiciliary / home healthcare benefits that can cover oxygen equipment rental or purchase. Check your policy for:
- Whether home oxygen is listed under domiciliary benefits
- Any minimum hospitalisation requirement before home-care benefits apply
- Whether consumables (cannulas, tubing) are covered
- Pre-authorisation requirements
Tip: Ask your hospital billing team or TPA (third-party administrator) — they process these claims regularly and know what your insurer typically covers.
🇧🇦 State-level schemes
Some states offer additional healthcare or disability assistance. Coverage varies widely — check with your District Disability Rehabilitation Centre (DDRC) or state health department for local options.
