2. IPAP
The IPAP setting displays if AVAPS is Off. You can increase or decrease the Inspiratory Positive Airway Pressure (IPAP) from 4 to 50 cm H2O in increments of 1. IPAP is limited to a maximum of 25 cm H2O when Flex is enabled. You cannot set the IPAP setting lower than the EPAP setting.
3. IPAP Max Pressure
Note: IPAP, IPAP Max, or IPAP Min cannot be set to more than 30 cm H2O above EPAP.
The IPAP Max Pressure setting displays if AVAPS is enabled. You can increase or decrease the setting from 4 to 50 cm H2O in increments of 1. The IPAP Max Pressure must be equal to or greater than the IPAP Min value.
4. IPAP Min Pressure
The IPAP Min Pressure setting displays if AVAPS is enabled. You can increase or decrease the setting from 4 to 50 cm H2O in increments of 1. The IPAP Min Pressure must be equal to or greater than the EPAP value, and it must be less than or equal to the IPAP Max Pressure.
5.EPAP
You can increase or decrease the Expiratory Positive Airway
Pressure (EPAP) from 4 to 25 cm H2O in increments of 1. For active circuits, EPAP can be set to zero.
When AVAPS is disabled, the EPAP setting must be less than or equal to the IPAP setting. When AVAPS is enabled, the EPAP pressure must be less than or equal to the IPAP Min Pressure.
6.Tidal Volume
The Tidal Volume setting displays if AVAPS is enabled. You can increase or decrease the setting from 50 to 2000 ml in 5 ml increments. Use this setting to establish the target volume of gas which the ventilator will produce and deliver during each Spontaneous breath.
Note: EPAP cannot be set to more than 30 cm H2O below IPAP, IPAP Max, or IPAP Min.
Note: In CV, AC, and SIMV modes, the tidal volume setting is limited by the Inspiratory Time, to maintain the system’s minimum and maximum peak flows.
