Using the ventilator

6.11 Calculation of oxygen content/remaining op-

erating time

Oxygen content of cylinder

Oxygen volume = volume of cylinder x cylinder pressure.

Real ventilation time

Example:

content = 1000 l; MV = 11 l/min.

This gives the following equation:

Cylinder volume

x cylinder pressure = oxygen content

Example 1

10 l

x 200 bar

= 2000 l

Example 2

10 l

x 100 bar

= 1000 l

Real ventilation time (min) =

oxygen content (l)

MV (l/min)

Real ventilation time =

1000 l

11 l/min

= 91 min = 1 h 31 min
