CYLINDER DURATION INFORMATION
The duration of compressed medical oxygen cylinders depends on the volume of the cylinder and the breathing
pattern of each patient, which can change throughout the day. Observe your daily oxygen consumption a few
times before estimating typical use. The following tables can be used to obtain approximate values only.
NOTE:
These tables use a PEEP value of 0 cmH
