To estimate how long an H cylinder will last at a flow rate of 12 liters per minute (Lpm) with 1200 psi, you first need to know the cylinder's capacity. An H cylinder typically holds about 244 cubic feet of oxygen, which is approximately 6,900 liters. At 12 Lpm, the duration can be calculated by dividing the total volume by the flow rate: 6,900 L / 12 Lpm = about 575 minutes. Therefore, the cylinder would last approximately 9.6 hours at that flow rate under ideal conditions.
A K cylinder, which typically contains around 6,900 liters of oxygen, will last approximately 11.5 hours when used at a flow rate of 10 liters per minute (LPM). To calculate this, divide the total volume of the cylinder by the flow rate: 6,900 liters ÷ 10 LPM = 690 minutes, or about 11.5 hours. However, actual duration may vary based on factors like the efficiency of the regulator and the patient's needs.
The duration a ZX oxygen cylinder lasts at a flow rate of 15 liters per minute (LPM) depends on the cylinder's size and pressure. For example, a standard E-cylinder (approximately 680 liters of oxygen) would last about 45 minutes at that flow rate. To get a more accurate estimate, you'll need the specific volume of the cylinder you're referring to.
To convert standard cubic centimeters per minute (sccm) to liters per minute (LPM), you can use the conversion factor that 1 liter equals 1,000 cubic centimeters. Therefore, to convert sccm to LPM, you divide the sccm value by 1,000. For example, if you have 500 sccm, the conversion to LPM would be 500 sccm ÷ 1,000 = 0.5 LPM.
To convert from standard liters per minute (slpm) to liters per minute (lpm), you need to know the standard conditions under which the slpm measurement was taken, as slpm refers to a volume flow rate at specific temperature and pressure conditions. If you are at the same conditions, 1 slpm equals 1 lpm. However, if conditions differ, you would use the ideal gas law or appropriate conversion factors to adjust for temperature and pressure differences, which may require specific calculations based on the gas properties.
1 cubic foot per minute (cfm) is approximately equal to 28.3165 liters per minute (lpm) at standard conditions. To convert cfm to normal liters per minute (nlpm), you typically need to account for specific temperature and pressure conditions, but under standard conditions, 1 cfm is roughly equal to 28.3165 nlpm.

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.
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).
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.
The duration a ZX oxygen cylinder lasts at a flow rate of 15 liters per minute (LPM) depends on the cylinder's size and pressure. For example, a standard E-cylinder (approximately 680 liters of oxygen) would last about 45 minutes at that flow rate. To get a more accurate estimate, you'll need the specific volume of the cylinder you're referring to.

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.
To convert standard cubic centimeters per minute (sccm) to liters per minute (LPM), you can use the conversion factor that 1 liter equals 1,000 cubic centimeters. Therefore, to convert sccm to LPM, you divide the sccm value by 1,000. For example, if you have 500 sccm, the conversion to LPM would be 500 sccm ÷ 1,000 = 0.5 LPM.
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. Need an Oxygen Cylinder?
