7.Ramp Start Pressure
You can increase or decrease the ramp start pressure in
increments of 1 from 4 cm H2O to the CPAP pressure setting. The patient also has access to this setting, unless the ramp length is set to Off.
8.Flex
You can enable or disable the Flex setting. Offf disables the setting and prevents the patient from using Flex. To enable the setting, set Flex to 1, 2, or 3. The patient also has access to this setting, if Flex is enabled. The Flex feature is not available when using an active circuit type.
Spontaneous (S) Mode
The following settings, described in the CPAP mode section of this chapter, also are available in S mode:
•• Flex
•• Trigger Type
•• Flow Trigger Sensitivity
•• Flow Cycle Sensitivity
•• Ramp Length
•• Ramp Start Pressure
In addition to those settings, the settings below are also available in
Smode.
1.AVAPS
AVAPS is only available if Flex is not enabled.
You can disable AVAPS by selecting Off, or you can enable AVAPS by selecting On. If you select Off, the IPAP setting displays. If you select On, the IPAP Max Pressure and IPAP Min Pressure display.
Note: The Ramp Start Pressure setting will not display if the Ramp Length is set to Off or if the CPAP pressure is set to
4 cm H2O.
Note: Ramp Start Pressure is less than or equal to CPAP - 1 cm H2O in CPAP mode.
Note: In CPAP mode, Flex is only available when CPAP is greater than 4 cm H2O.
Note: In S mode, Flex is only available when EPAP is greater than or equal to 4 cm H2O and IPAP is less than or equal to 25 cm H2O.
Note: Flex is only available when
Note: Ramp is not available in the Passive Circuit when IPAP = EPAP = 4 cm H2O or when IPAP Min = EPAP = 4 cm H2O.
Note: Ramp Start Pressure is less than or equal to EPAP - 1 cm H2O in S, S/T, T, and PC modes.
Note: Ramp Start Pressure is greater than or equal to 0 cm H2O when the circuit type is Active PAP or Active Flow in S, S/T, T, and PC modes.
Note: Ramp Start Pressure is greater than or equal to 4 cm H2O when the circuit type is Passive in S, S/T, T, and PC modes.
Note: AVAPS is only available if the Passive Circuit is selected.
