Technical specifications

Operating pressure range
4 to 20 cm H O (4 to 20 hPa)
2
Maximum single fault steady state pressure
Device will shut down in the presence of a single fault if the steady state pressure exceeds:
40 cm H O (40 hPa) for more than 1 second.
2
Pressure measurement tolerance
± 0.5 cm H
O (0.5 hPa) ±4% of measured reading
2
Flow measurement tolerance
± 6 L/min or 10% of reading, whichever is greater, at 0 to 150 L/min positive flow
Mode pressure ranges
CPAP: 4-20 cm H
O (4-20 hPa) (measured at the mask)
2
CPAP with EPR mode: 4-20 cm H
(2 hPa), Level 3 = 3.0 cm H
AutoSet, AutoSet for Her mode: 4-20 cm H
AutoSet, AutoSet for Her mode with EPR: 4-20 cm H
Level 2 = 2.0 cm H O (2 hPa), Level 3 = 3.0 cm H
2
EPR reduces the pressure during expiration by the amount dependent on the level set above, but the pressure delivered will not
drop below 4.0 cm H O (4 hPa).
2
Flow (maximum) at set pressures
The following are measured according to ISO 80601-2-70 201.12.1.103:
