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.
7. Rise Time
You can adjust the rise time to find the most comfortable setting for the patient. Increase or
decrease the setting from 1 to 6 until you find the right setting. The rise time of 1 to 6 corresponds
to tenths of a second (e.g., a setting of 4 equals 0.4 second rise time).
8. Apnea Rate
If the Apnea alarm is enabled, you can set the Apnea Rate from 4 to 60 BPM in 1 BPM increments.
In S mode, the Apnea Rate is greater than or equal to 1:2 I:E ratio.

ODE
All of the settings described in the S Mode section are also available in S/T mode, except the Flex setting. In
addition to those settings, the settings below are also available in S/T mode.
1. Breath Rate
In AC mode, you can increase or decrease the Breath Rate setting from 0 to 60 BPM, while in all
other modes, you can increase or decrease the setting from 1 to 60 BPM in 1 BPM increments.
Use the Breath Rate setting to establish the minimum rate of mandatory breaths that the ventilator
will deliver per minute.
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.
NOTE
The Rise Time setting only displays if Flex is disabled. If the Flex is enabled, the device
will use a rise time of 3.
NOTE
In S/T, T, PC, PC-SIMV, SIMV, CV, and AC modes, the Apnea Rate is greater than or equal to the
Breath Rate and is limited by the current Inspiratory Time setting to maintain a minimum 1:1 I:E ratio.
NOTE
In volume modes, the Breath Rate range is limited by the current Inspiratory Time
setting to maintain a minimum 1:1 I:E ratio.
