Service Manual
The
Resp Rate
(respiratory rate) setting determines the minimum number of time-triggered or
patient-triggered mandatory breaths delivered each minute. The
Trig
setting determines the airway
pressure or airway flow threshold that the patient’s effort must reach in order to trigger these and
additional mandatory breaths.
If the patient doesn’t breathe or if the patient’s efforts don’t cause airway pressure or airway flow to
reach the
Trig
threshold, the ventilator delivers the number of time-triggered breaths each minute
selected via the
Resp Rate
setting.

SIMV
Figure A-5.
SIMV
In SIMV, mandatory and spontaneous breaths may be delivered to the patient. The user may choose
to Pressure Control, Volume Control, Biphasic Pressure Release* or Volume Target Pressure Control*
the mandatory breaths. Mandatory breaths may be time or patient triggered. In Volume Control,
Pressure Control, or Biphasic Pressure Release*, the user may choose Pressure Support to augment
the spontaneous breaths.
When Volume Target Pressure Control* mandatory breath type is selected, all spontaneous breaths
are Volume Target Pressure Support breaths.
The
Resp Rate
setting determines the total number of mandatory breaths delivered each minute
and establishes a timing window that determines whether a patient trigger results in a mandatory
breath or a spontaneous breath.
The
Trig
setting determines the airway pressure or airway flow threshold that the patient’s effort
must reach in order to trigger mandatory breaths and also to trigger spontaneous breaths in
between mandatory breaths.
If there are no patient breathing efforts or if patient efforts fail to cause enough airway pressure or
airway flow change to meet the set
Trig
threshold, the patient receives the number of time-
triggered breaths each minute selected via the
Resp Rate
setting.
