SIMV PCV mode
Synchronized intermittent ventilation with pressure control ventilation
(SIMV PCV) delivers a relatively slow breathing rate with pressure-
controlled breathing. This mode combines mandatory breaths with
spontaneous breath support. If a trigger event occurs within the
synchronized window, a new pressure-controlled breath is initiated. If
a trigger event occurs elsewhere during the expiratory phase, a
support for a spontaneous breath is provided with pressure support
added as set by the clinician.
