SIMV PCV mode
• Delivers a relatively slow breathing rate with pressure controlled breathing
• 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.
