SIMV (Synchronized intermittent mandatory ventilation)
- A common mode of ventilation that all pratitioners should be familiar with
- It provides a minimum number of fully assisted breaths synchronized with patient respiratory effort
- Patient or time triggered
- Flow limited
- Volume cycled
- Any additional breaths are unassisted and determined by patient effort
- SIMV=AC when heavily sedated
- The idea is exercise the patients lungs but this can lead to increased work of breathing and fatigue, and prolong extubation when used
