The cubic footage is, rounded off for convenience The volumn, whether liters or cubic feet is dependent on pressure. Oxygen Tank Size Duration Times. Jun 1, 2015 #2 . The E cylinder reads 2200 psi on the gauge. Assuming oxygen fresh gas flow of 1 L/min, calculating tank duration with the fastest consumption rate underestimated the tank duration for more compliant and smaller Vt models but provided a greater margin of patient safety. Therefore, the estimated oxygen consumption for the planned transport duration of 2 hours is approximately 712 liters. E = 5.4 L/min Formula: V E = Respiratory Rate x Tidal Volume . 6.8ltr Cylinder TV = 2,040 divide by 40 = 51 minutes e.g 10.0ltr Cylinder TV = 3,000 divide by 40 = 75 minutes This calculation does not include a safety factor and is based on average breathing rates and cylinder going from completely full to completely empty. To calculate the total time left, multiply the total pressure left with the constant value of 0.35. What is the formula for finding the duration of flow of oxygen in a tank in minutes? 1 Cubic ft. equals 28.31 liters.
