Determining the approximate pneumatic
operating time
Example for supply of O2:
– Cylinder pressure measured on the pressure gauge
of the pressure reducer: 20000 kPa (200 bar)
– Liquid capacity of the O
2 cylinder: 2.1 L
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
2 = 100%
Minute volume = 10 breaths/min x 0.53 L = 5.3 L/min
Operation time =
* Calculated with average gas consumption of ventila-
tor: 0.5 L/min
Operation time = = approx. 72 minutes
The pneumatic operation time increases when
Oxylog 3000 plus operates with O
2 concentration of
less than 100% O
2, as ambient air is drawn into the de-
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.
Example:
O
2 consumption = 5.3 L/min.
Supply from a piped O2 system
1 Connect the O2 hose (A) to the Oxylog 3000 plus.
2 Connect the gas probe (B) to the O
2 terminal unit
until it has properly engaged and the supply of O
2 is
assured.
