Single limb with valve or double limb with valve: 3 to 50 hPa
Single limb with intentional leak: 2 to 50 hPa
CPAP: 3 to 20 hPa
Maximum working pressure limit: 10 to 55 hPa
Forced cycling occurs if the Pressure alarm limit is exceeded.
Adult patient type: 100 to 2500 mL
Paediatric patient type: 50 to 300 mL*
60 hPa (in all modes)
Paediatric patient setting:

L/min
Circuit resistance range (circuit with valve): 0 to 20 hPa at 60 L/min
Circuit compliance range: 0 to 4 mL / hPa
Adult patient setting:

L/min
Circuit resistance range (circuit with valve): 0 to 35 hPa at 120 L/min
Circuit compliance range: 0 to 4 mL / hPa
Paediatric circuit
Inspiration: 2.2 hPa (at 15 L/min), 5.3 hPa (at 30 L/min)
Expiration: 2.4 hPa (at 15 L/min), 5.0 hPa (at 30 L/min)
Adult circuit
Inspiration: 5.7 hPa (at 30 L/min), 8.3 hPa (at 60 L/min)
Expiration: 4.2 hPa (at 30 L/min), 6.2 hPa (at 60 L/min)
220 L/min
Inspiratory trigger occurs when patient flow exceeds trigger setting.
Double limb with valve (flow trigger): 0.5 to 15.0 L/min
Single limb with valve or double limb with valve: 1.6 to 10.0 L/min (in five
steps)****
Single limb with intentional leak: 2.5 to 15.0 L/min (in five steps)
Cycle occurs when inspiratory flow declines to the set percentage of peak
inspiratory flow.
