Determining the approximate pneumatic
operating time
Example for supply of O
– Cylinder pressure measured on the pressure gauge
of the pressure reducer: 20000 kPa (200 bar)
– Liquid capacity of the O
Supply of O :
2
2.1 L x 20000 kPa = approx. 420 L at environmental
pressure level.
Example for pneumatic operation time:
VC-CMV mode, frequency 10 breaths/min, VT = 0.53 L,
O = 100%
2
Minute volume = 10 breaths/min x 0.53 L = 5.3 L/min
O supply [L]

Operation time =
(MV + 0.5*) [L/min]
* Calculated with average gas consumption of ventila-
tor: 0.5 L/min
420
Operation time = = approx. 72 minutes

The pneumatic operation time increases when
Oxylog 3000 plus operates with O
less than 100% O , as ambient air is drawn into the de-
2
vice.
The amount of gas from the high-pressure supply, which
is currently being consumed, is indicated by the
Oxylog 3000 plus in the lower left section of the informa-
tion window in L/min. This display is overwritten when a
higher priority message is activated.
