Overview of Ventilator Modes VC - Volume Control (a.k.a. assist control volume) - Every breath delivered (mandatory and patient triggered) is the same set volume (TV) PC - Pressure Control (a.k.a. assist control pressure) - Every breath delivered (mandatory & patient triggered ) is a set pressure (IP) for a set time PRVC - Pressure Regulated Volume Control (a.k.a. VC., APV, Auto flow) - Hybrid PC mode that dynamically changes inspiratory pressure to deliver a desired volume SIMV - Synchronous Intermittent Mandatory Ventilation - Delivers mandatory breaths with a fixed volume but patient can't trigger (patient breaths are not the same as mandatory breaths); can use PS PS - Pressure Support - All breaths are patient initiated; ventilation determined solely by patient (no backup rate). APRV - Airway Pressure Release Ventilation (a.k.a. BI-Vent) - Inverse ratio ventilation (e.g. I time > E time) that allows patient to breath spontaneously; can combine w/ PS Nick Mark MD @nickmmark #Ventilator #Modes #Ventilation #CriticalCare #Comparison #Management #Mechanical
