PSVPro mode settings
Minimum monitoring
6-22
An apnea backup mode is provided in the event the patient stops breathing.
When setting the backup mode the user adjusts the inspiratory pressure
(Pinsp), respiratory rate and the inspiratory time (Tinsp). As long as the patient
triggers the ventilator within the set apnea delay time, the patient will get
pressure-supported breaths and the ventilator will not deliver machine
breaths. The apnea delay time can be set from 10 to 30 seconds with the
default set at 30 seconds.
If the patient stops triggering the ventilator for the set apnea delay period, an
audible alarm activates and the ventilator automatically switches to the
backup mode. The backup mode is an SIMV (Pressure Control) + PSV mode.
Once in this mode the ventilator will begin delivering machine Pressure
Control breaths at the inspiratory pressure level, inspiratory time and rate that
the user has set. If, during this mode, the patient takes spontaneous breaths
in between the machine breaths, the patient will receive pressure supported
breaths.

When the ventilator switches to the backup mode the alarm text "Backup
Mode Active" will be displayed and will remain in the low priority message site
until PSVPro is re-instated or until another mode is selected. To re-activate the
PSVPro mode the user must go into the Ventilation Mode menu and re-select
PSVPro. Upon selecting PSVPro the ventilator will immediately begin providing
pressure supported breaths to the patient using the established settings.
