SYNCHRONIZED INTERMITTENT MANDATORY VENTILATION MODE
DEFINITION
Synchronized Intermittent Mandatory Ventilation (SIMV) mode ensures that
spontaneously or partially spontaneously breathing patients receive a set
number of mandatory breaths. All breath types are available in this mode. This
mode is identical to Assist/Control mode except for the following:
ï‚· Patient spontaneous breaths are allowed between mandatory breaths.
 Although mandatory breaths are synchronized with the patient’s inspiration,
the breath period is not reset when the patient initiates an assist breath;
therefore, average mandatory bpm does not change.
AVAILABLE BREATH TYPES
