| Your mother has been prescribed home oxygen. The medical store near your house is offering you two options: an oxygen cylinder for Rs.800 refill, or an oxygen concentrator machine on rent. You are not sure which is better, safer, or more practical for home use in Delhi. |
Both are legitimate oxygen delivery methods. They are not interchangeable for all situations. The right choice depends on how much oxygen the patient needs, for how many hours per day, and your practical home situation.
Oxygen Cylinder
An oxygen cylinder is a pressurised metal container filled with 100% medical-grade oxygen. A flow regulator controls how many litres per minute reach the patient. When the cylinder is empty, it must be refilled or replaced.
Two common sizes for home use: the 10L cylinder (smaller, lighter, roughly 5 to 6 hours at 2 LPM) and the 47L cylinder (standard large home cylinder, roughly 24 to 30 hours at 2 LPM). Most families prescribed daily oxygen need the 47L as the primary or backup source.
Oxygen Concentrator
An oxygen concentrator pulls room air in, separates out the nitrogen, and delivers oxygen at 87 to 96% purity continuously through a nasal cannula or mask. It runs on electricity and produces oxygen as long as it is powered. It never needs refilling.
Available in 5 LPM capacity (Philips EverFlo, Niscomed, Evox, Medoxy) for prescriptions up to 5 LPM, and 10 LPM capacity for higher flow requirements.
| Factor | Oxygen Cylinder | Oxygen Concentrator |
| How it works | Pre-filled pressurised oxygen, depletes over time | Produces oxygen from room air, continuous while powered |
| Running cost | Refill cost per cylinder. 47L at 2 LPM lasts approx. 24-30 hours | Electricity only. Approx. Rs.20-25 per day at 16 hours use |
| Power dependency | None, works during power cuts | Requires electricity, stops immediately on power cut |
| Supply continuity | Finite, runs out | Unlimited while powered |
| Daily oxygen therapy (15 hours plus) | Not practical, too many cylinders needed | Strongly recommended, designed for this |
| Short-term or intermittent use | Practical, no running cost between uses | Rental makes it less cost-efficient for very short use |
| Outdoor or travel use | Portable 10L cylinder is feasible | Portable concentrators available but bulkier |
| Safety | Pressurised vessel, must store upright, away from heat | No pressurised storage, safer for home use |
| Noise | Silent | 40-50 decibels, similar to refrigerator hum |
| Maintenance | Minimal, just regulator cleaning | Weekly filter cleaning required |

The recommended home setup for daily oxygen patients:
One oxygen concentrator as the primary source, plus one fully charged 47L cylinder as backup. The cylinder is reserved exclusively for power cuts. Every COPD or chronic respiratory patient in Delhi NCR needs this backup. Power outages during a hypoxemic episode without backup oxygen are a medical emergency.

| Flow Rate (LPM) | Duration of 47L Cylinder | Daily Oxygen Hours | Cylinders Needed Per Day |
| 1 LPM | Approx. 48-55 hours | 24 hours | 0.5 (half cylinder per day) |
| 2 LPM | Approx. 24-30 hours | 16 hours | 0.6 (approx.) |
| 3 LPM | Approx. 16-20 hours | 16 hours | 0.9 (nearly 1 per day) |
| 5 LPM | Approx. 9-10 hours | 8 hours | 0.9 (nearly 1 per day) |
At 2 LPM for 16 hours daily, one 47L cylinder lasts approximately 1.5 to 2 days as the sole source. As a backup used only during power cuts of 1 to 4 hours daily, one cylinder can last weeks to months. This is why using a concentrator as primary with a cylinder backup is economically sensible.
Q: Can I use a cooking gas cylinder connection for medical oxygen?
Absolutely not. Medical oxygen cylinders use specific regulator connections that are not compatible with cooking gas. Medical oxygen is also different from industrial oxygen. Always use certified medical oxygen cylinders from a licensed supplier.
Q: Is a 5L or 10L portable cylinder enough for an outing?
At 2 LPM, a 10L portable cylinder lasts approximately 5 to 6 hours. Sufficient for a hospital visit or a half-day outing. For longer outings, carry a spare 10L cylinder or use a portable oxygen concentrator.
Q: Can I rent just a cylinder for a few days without a concentrator?
Yes. Sanjeevia rents 10L and 47L cylinders for short-term needs. Contact us via WhatsApp for same-day delivery.
