synchronized intermittent mandatory ventilation
Also written as: SIMV — Synchronized Intermittent Mandatory Ventilation
Ventilation mode delivering mandatory breaths synchronized with patient's respiratory effort.
Full Definition
A mechanical ventilation mode that provides a preset number of mandatory breaths per minute while allowing spontaneous breathing between these breaths. The key feature is synchronization with the patient's own respiratory efforts, which reduces fighting the ventilator and improves gas exchange efficiency. SIMV is commonly used in neonatal intensive care as it allows gradual weaning from mechanical support while providing backup ventilation security.
