Dräger Oxylog 3000 plus - Determining Approximate Pneumatic Operating Time

Instructions for use Oxylog 3000 plus SW 1.n 53
Getting started
Determining the approximate pneumatic operating time
Example for supply of O2:
– Cylinder pressure measured on the manometer
of the pressure reducer: 20000 kPa
(200 bar)
– Filling quantity of the O
2 cylinder: 2.1 L
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
2 = 100 %
– Minute volume = 10 breaths/min × 0.53 L =
5.3 L/min
Operation time =
* Average gas consumption of the ventilator:
0.5 L/min
Operating time = = approx. 72 minutes
The pneumatic operation time increases when
Oxylog 3000 plus operates with an O
2
concentration of less than 100 % O2, as ambient air
is drawn into the device.
The amount of gas from the high-pressure supply
currently being consumed is indicated by
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.
