Basic Modes of Ventilators
basic modes of ventilators
- volume control: machine triggered, flow targeted, volume cycled
- volume assist: patient triggered, flow targeted, volume cycled
- pressure control: machine triggered, pressure targeted, time cycled
- pressure assisted: patient triggered, pressure targeted, time cycled
- pressure support: patient triggered, pressure targeted, flow cycled

Triggers, Limits, Cycles of Ventilators
triggers, limits, cycles of ventilators
- trigger: what initiates each breath
- assisted breaths are triggered by patient
- controlled breaths are triggered by machine
- limits: the target for each breath. Could either be pressure or flow (volume)
- flow targeting: ventilator adjusts pressure to maintain flow
- pressure targeting: ventilator adjusts flow to maintain inspirator
