This will depend upon the gas flow rate. A size E oxygen cylinder in the UK contains 680 litres of compressed gas. At a flow of 10L/min for medical emergency use the cylinder will therefore last 68 mins. However if used at 6L/min it will last nearly 2 hours.
In the US we use PSIG (gauge level). at full a tank is about 2200 PSI on any given tank size, and the E cylinder has a tank factor of 0.28. So you take take the PSI and multiple it by by the tank factor and divide that number by the flow rate. So at full, 2200 x 0.28 = 616 and dvided that by the flow rate. The final number is the total number of minutes at the given flow rate. So at 2 liters per minute (2 lpm) a completely full E cylinder will last 308 minutes or 5.13 hours (divide total minutes by 60 to get hours). 140 minutes at 4lpm, and so on. You deffinetly want to call your oxygen supplier well before the guage gets to the red. With most guages the very start of the red line (the end farthest from empty) is around 500 PSI.
A good rule of thumb is to round down to the nearest whole hour when figuring duration. So when I've needed to I look at 5.16 hours and say 5 hours.
If you do run out or are into the red already, call 911 (or your local emergency service), all ambulances carry oxygen and better to have them arrive and use their O2 than to call your oxygen service because ambulance should be able to get their faster. Remember, at the very beginning of red (500 PSIG) a E cylinder will only last 140 divided by flow rate...so 70 minutes at 2lpm, 35 minutes at 4lpm, etc. Dont risk it, when in red, call 911 first, then your oxygen supplies...that is as long as you dont have any other cylinders to use.
common tank factors:
H Cylinder factor is 3.14
D cylinder factor is 0.16 (typical portable oxygen size)
* in the USA, all oxygen tanks, when completely full, are 2200 PSI, if you know the tank factor, you can easily compute the duration.
Calculating liquid oxygen is a whole nother ball of wax....
H size Cylinder holds 6900 liters @ 10 lpm =690 min or 11.5 hrs
@ 3 lpm = aprox 33 hrs
Know the lpm of your device & do the math
That really depends on how fast you use the oxygen, if you fully open the valve to air the cylinder will vent off (empty) within a couple minutes, if you just use a little at a time it could last for hours, days or even weeks.
There are many variables unknown to give an exact answer to the question. Such as: * The size of the cylinder * The oxygen delivery system. Nasal cannula, regular oxygen mask or high flow rebreather. * The oxygen flow or how many liters per minute are being administered to the patient.
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.
An Oxygen tank will only last as long as its flow rate or pulse dose rate. A m6 oxygen cylinder will last on continuous flow of 2.7 for one hour, and a pulse rate of 8.3 for one hour.

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 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 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 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 many minutes will a c size oxygen cylinder last using 8 liters per minute?
A standard C size oxygen cylinder typically holds around 1700 liters of oxygen. To calculate the duration, divide the cylinder's capacity (1700 liters) by the flow rate (8 liters per minute) to get the total minutes. In this case, the C size oxygen cylinder would last approximately 212.5 minutes (1700 / 8 = 212.5 minutes).
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 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.
What is an e cylinder?
An "E cylinder" is a particular size of oxygen cylinder. 29" tall just under 5" diameter with a capacity of 680 liters of oxygen.
How long will a size d oxygen cylinder last at 2lpm?
A size D oxygen cylinder typically contains around 418 liters of oxygen. At a flow rate of 2 liters per minute (LPM), the cylinder would last approximately 209 minutes or about 3.5 hours.
What is an H oxygen cylinder?
An H oxygen cylinder is a type of compressed gas cylinder that contains oxygen. It is commonly used in medical and emergency settings to provide supplemental oxygen to patients who have difficulty breathing. The "H" designation typically refers to the size or capacity of the cylinder.
How long will a size c oxygen tank last on 2 lpm?
A size C oxygen tank typically holds around 1700 liters of oxygen. If you are using 2 liters per minute, the tank will last for approximately 850 minutes, or about 14 hours.
How long will a size H cylinder of heliox r last?
The duration a size H cylinder of heliox will last depends on the flow rate it is used at. For example, if the flow rate is 4 liters per minute, a size H cylinder typically lasts around 4.5 hours. You can calculate the estimated duration by dividing the cylinder's capacity (in liters) by the flow rate (in liters per minute).
