The duration for which a 10-litre oxygen cylinder lasts depends on the flow rate prescribed by the doctor and the cylinder pressure. Here's a simple way to estimate it:
Formula:
Cylinder Duration (in hours) = (Cylinder Volume in Litres × Pressure in Bar) / Flow Rate (Litres per Minute)
Example Calculation:
If a 10-litre cylinder is filled to 150 bar pressure and the oxygen flow is set at 2 LPM (litres per minute):
Duration = (10 × 150) / 2
Duration = 750 minutes or approximately 12.5 hours
If the flow rate increases to 5 LPM, the duration reduces to approximately 5 hours.
Factors Affecting Cylinder Duration:
Flow Rate: Higher flow rates consume oxygen faster.
Cylinder Pressure: Full cylinders last longer compared to partially filled ones.
Usage Pattern: Continuous use will deplete the oxygen faster compared to intermittent use.

How long will a D oxygen cylinder last at 10 lpm?
A D oxygen cylinder typically contains about 415 liters of oxygen. At a flow rate of 10 liters per minute, the cylinder would last approximately 41.5 minutes.
How long will a c oxygen cylinder last on 2lpm?
A C oxygen cylinder typically holds about 3400 liters of oxygen. At a flow rate of 2 liters per minute, it will last for approximately 28 hours.
How long will a size d oxygen cylinder last at 4 liters?
A size D oxygen cylinder typically contains 425 liters of oxygen. At a flow rate of 4 liters per minute, the cylinder would last approximately 106 minutes.
How long will an E oxygen cylinder last at 4 LPM?
A size E oxygen cylinder typically holds around 6800 liters of oxygen. At a flow rate of 4 liters per minute, the cylinder would last for approximately 1700 minutes, or about 28 hours.
How long will a ml6 oxygen cylinder last?
An ML6 oxygen cylinder, when "charged" to normal pressures, holds 170 liters of oxygen. How long that will last depends on a number of factors. If the flow is set to 2 liters per minute continuous then it will last less than 1 and 1/2 hours. If an oxygen conserving device is used (they give the gas in pluses when breaths are taken) it can last over 4 hours.
How long will a c oxygen cylinder last?
The duration a c oxygen cylinder will last depends on the flow rate at which the oxygen is being used. For example, if the flow rate is 1 liter per minute, a C oxygen cylinder (with a volume of around 2400 liters) may last for around 40 hours. It is advisable to consult with a healthcare provider for more precise estimations based on individual oxygen needs.
How long will a size E oxygen cylinder last with a regulator at 2.0?
The duration a size E oxygen cylinder will last depends on the flow rate in liters per minute set on the regulator. A size E cylinder typically holds around 680 liters of oxygen. At a flow rate of 2.0 liters per minute, the cylinder would last approximately 340 minutes, which is about 5.7 hours.
How long will a J size oxygen cylinder last?
The duration a J size oxygen cylinder will last depends on the flow rate at which the oxygen is being accessed. To calculate this, you need to divide the cylinder's capacity (in liters) by the flow rate (in liters per minute) to determine the approximate duration in minutes. For a more accurate estimation, consult with a medical professional or oxygen provider.
How long does an E oxygen cylinder run on 2 L?
An E oxygen cylinder typically contains around 680 liters of oxygen when filled to capacity. At a flow rate of 2 liters per minute, the cylinder would last approximately 340 minutes or about 5.7 hours.
How long will a over size D oxygen cylinder last?
The duration of an oversized D oxygen cylinder will depend on the flow rate at which the oxygen is being delivered. Typically, an oversized D cylinder can last between 6 to 10 hours when used continuously at a flow rate of 2 liters per minute. It is recommended to consult with a medical professional for a more accurate estimation based on individual oxygen therapy needs.
How long will a full e cylinder last at 5lpm?
A full E cylinder typically holds 680 liters of oxygen. At a flow rate of 5 LPM, the E cylinder would last approximately 136 minutes (2 hours and 16 minutes).
How long will a size G oxygen cylinder last?
The duration a size G oxygen cylinder will last can vary based on the flow rate of oxygen being used. On average, a size G cylinder can last for about 7-8 hours at a flow rate of 2 liters per minute. It is best to consult with a healthcare provider or oxygen supplier for more accurate information based on your specific oxygen needs.
