5.8.1 Automode in detail
1. The ventilator system starts in PC, PRVC
or VC mode. If the patient triggers a
breath, the ventilator system will turn to
the relevant supported mode to encourage
the patient's respiratory drive.
2. If the patient is breathing adequately:
In VS, the ventilator system adjusts the
inspiratory pressure level on a
breath-by-breath basis to ensure
delivery of the preset target volume.
a.
b. In PS, the ventilator system ensures
that the preset inspiratory pressure
level is maintained throughout
inspiration.
3. The ventilator system initially adapts with
an increasing apnea time.This means that
for the spontaneously triggering patient,
the apnea time increases successively
until the level set in the settings window
for the maximal apnea time parameter is
reached after 10 consecutive
spontaneously triggered breaths.
Refer to section Settings on page 43.
4. Exceeding the maximal apnea time setting
without a sufficient patient effort will cause
the following:
In VS, a PRVC or VC breath will be
delivered according to the selected
Automode functionality.
a.
b. In PS, a PC breath will be delivered.
5. The rings in the figures indicate patient
triggering.
