11.1.3 Double circuit
11.2 System resistances
The total pneumatic resistance of the connected circuit and
of the connected accessories (e.g. humidifier, breathing
system filter) between the device and the patient connection
may not exceed the following value:
Circuits with a
diameter of 15 mm and 22 mm
:
Pressure drop < 3.2 cmH
2
O at a flow = 30 l/min (BTPS)
.
Circuits with a
diameter of 10 mm
(intended for volumes
delivered of < 50 ml):
Pressure drop < 3.2 cmH
2
O at a
flow = 2.5 l/min (BTPS)
.
The pressure drop values of the individual components can
be added to form a total resistance value which must not
exceed the value mentioned above.
Maximum error in pressure measurement: 0.0125 cmH
