Getting Started
Determining the approximate pneumatic operating time for the
Oxylog 3000
Example for supply of medical gas:
– Cylinder pressure measured on the pressure
gauge of the pressure reducer: 2000 kPa
– Liquid capacity of the O
2
cylinder: 2.1 L
Supply of medical gas:
2.1 L x 2000 kPa = approximately 420 L
Example for pneumatic operation time:
– IPPV mode, frequency 10 breaths /min,
VT = 1 L, O
2
= 100%
– Minute volume = 10 breaths /min x 1 L =
10 L/min
Operation time =
* Calculated with average gas consumption of
ventilator: 0.5 L/min
Operation time = = approx. 40 minutes
The pneumatic operation time increases when
Oxylog 3000 operates with O
2
concentration of less
than 100 % O
2,
as ambient air is drawn into the
device.
The amount of gas from the high-pressure supply,
which is currently being consumed, is indicated by
the Oxylog 3000 in the lower left section of the
information window in L/min. This display is over-
written when a higher priority message is activated.
