Operating Time - Dräger Oxylog 3000 plus Instructions For Use Manual

Determining the approximate pneumatic operating time
Example for supply of O
– Cylinder pressure measured on the manometer
of the pressure reducer: 20000 kPa
(200 bar)
– Liquid capacity of the O
Supply of O :
2
2.1 L × 20000 kPa = approx. 420 L at ambient
pressure.
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 = 2
(MV +0.5*) [L/min]
* Average gas consumption of the ventilator:
0.5 L/min
420
Operation time =
5.8
The pneumatic operation time increases when the
Oxylog 3000 plus operates with an O
concentration of less than 100 % O
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 plus in the lower left section of the
information window in L/min. This display is
overwritten when a higher priority message is
activated.
