Specications listed are based on using a standard circuit consisting of 1.8 meter tubing- REF 622038, one of the following exhalation
devices: Whisper Swivel II - REF 332113; Active PAP Exhalation Device - REF 1053716; Active Flow Exhalation Device - REF 1049503 or
Active Exhalation Device – REF 1065658; UPB Active PAP Exhalation Device - REF 1073862 and
Trilogy Proximal Flow Sensor- REF 1050408 (if required).
1Limited to 25 cm H2O when using the Bi-Flex feature in S mode.
2Pressure units may be cm H2O, hPa, or mBar depending on device setup.
3The dierence between the Inspiratory Pressure and the Expiratory Pressure must never be more than 30 cm H2O.
4Pressure Support and PEEP not to exceed 50 cm H2O.
5All ows and volumes are measured at BTPS conditions.
6The range of values correspond to tenths of seconds (e.g., a setting of 4 indicates a Rise Time of 0.4 seconds).
7Flex is not available when AVAPS is active. Flex is not available with Active Circuits.
