Vt/IBW
The system calculates the default tidal volume in the ventilation mode based on the [Vt/IBW] value.
It is available for the VCV, SIMV-VC, PCV-VG, and SIMV-VG modes.
Vt Source
Set the [Vt Source] to [IBW] or [Patient Type]. When the [Vt Source] is set to [Patient Type],
changes to [IBW] won't impact [Vt] setting. When the [Vt Source] is set to [IBW], changes to [IBW]
will impact [Vt] and [RR] settings based on the aforementioned Vt/IBW result.
Time Control
When [Time Control] is set to [I:E], the time control parameter in the VCV, PCV and PCV-VG
ventilation modes is [I:E], and that in the PS and CPAP/PS ventilation modes is [Apnea I:E]. When
[Time Control] is set to [Tinsp], the time control parameter in the VCV, PCV and PCV-VG ventilation
modes is [Tinsp], and that in the PS and CPAP/PS ventilation modes is [Apnea Ti].
Pressure Display
Set the pressure monitoring to display on the Main Screen to [Plat] or [Mean].
