12 Technical description
High pressure (HP) and low pressure (LP) O2 inlets
Minimum limited pressure
(P lim min)
Back-up ambient air intake preventing a pressure
drop in the patient circuit
(1) Consumption example:
•
For an adult, average consumption is 6 l/min of gas (air or oxygen;
•
The flow-by + internal consumption of the unit is fixed at 4 l/min.
In the case of a B5 type cylinder being used, its volume is 5 litres. Because the gas is compressed
to 200 bar, in this case we have 1000 litres of gas. In our example, we will therefore have approxi-
mately 1 hour 40 minutes of operating time if the ventilation is carried out at 100% oxygen concen-
tration.
(2) The above-mentioned resistances take the ventilator and the circuit into account, but exclude
any other intermediate accessory. For accessories other than those mentioned in this manual,
please contact us. The test method is also available on request.
