O2 E cylinder - OpenAnesthesia

Oxygen cylinders can be pressurized up to 2200 PSIG. Time Remaining: O2 E Cylinder. Time remaining (hrs) = Pressure (PSIG) / [200 x flow rate (L/min)] Time remaining (hrs) using 0.5 L/min of flow = Pressure (PSIG) / (100) At a flow rate of 0.5 L/min, a full E-cylinder (2200 PSIG) will provide 22 hours of gas flow.
