Notes:
• The previous mode function is not
available:
- after a pre-use check
- after changing the patient category
- after admitting a new patient
- after using the same ventilation mode
for more than 24 hours
- after restarting the system.
• When the previous mode function is
activated during backup ventilation, the
ventilator system returns to the mode
that was active before the supported
mode was initiated.
• A recall of previous settings is only
possible after a change of ventilation
mode.
6.15 Apnea management
6.15.1 Apnea time
Apnea time is the time without a patient
breathing effort that the ventilator system will
allow to elapse in supported ventilation before
the No patient effort alarm is activated and the
ventilator system switches to the backup
mode.
The relevant backup mode is highlighted in
white in the heading on the screen and the
alarm No patient effort is displayed.
If the patient triggers a breath, the ventilator
system automatically switches back to
supported ventilation and the No patient effort
alarm disappears.
Apnea time is available in all supported modes
and in all SIMV modes. Set the apnea time
that is appropriate for each patient in the mode
settings window.
Note: In SIMV modes, there is no backup
ventilation and the apnea time only controls
the No patient effort alarm. The apnea time
is therefore set in the ALARM LIMITS
window.
Refer to chapter Alarm handling on page 111
and to section Alarm limits on page 147.
