Pressure Control - Synchronized Intermittent Mandatory
Ventilation (PC-SIMV) Mode
The Pressure Control – Synchronized Intermittent Mandatory
Ventilation (PC-SIMV) mode provides Spontaneous, Assist, and
Mandatory breaths. This mode uses a time window to decide
what type of breaths should be delivered. This time window is the
maximum time between breaths according to the set Breath Rate.
When you enter PC-SIMV mode, the time window is started. If
the patient does not trigger a breath, the ventilator will provide
a Mandatory breath when the time expires and then begin the
process again. Mandatory breaths deliver the Pressure setting during
inhalation and a lower Peak End Expiratory Pressure (PEEP)
during exhalation.
