Volume control (VC): Ventilator delivers a clinician-determined tidal volume (V T) for each breath regardless of whether the breath was time or patient triggered.

No respiratory rate is set, so there is no guaranteed minute ventilation. Delivers a clinician-determined inspiratory pressure during patient-triggered breathing.

Pressure support ventilation (PSV): Spontaneous mode of ventilation without a set respiratory rate.

This mode is commonly used in surgical patients. The size of the patient-triggered breath depends on lung compliance and patient’s effort. However, when the breath is patient triggered, the ventilator delivers a pressure-supported breath (at a level set by the clinician).

Synchronized intermittent mandatory ventilation (SIMV): Ventilator delivers a fully supported breath when time triggered.

Primary mode of ventilation used in respiratory failure. Assist-control (AC) ventilation: Ventilator delivers a fully supported breath whether time or patient triggered.Initiation of a breath: Triggering of a ventilator occurs after a period of time has elapsed (time triggered) or when the patient has generated sufficient negative airway pressure or inspiratory flow exceeding a predetermined threshold (patient triggered).Basic modes of ventilation: One can determine how the ventilator initiates a breath (triggering), how the breath is delivered, how patient-initiated breaths are supported, and when to terminate the breath to allow expiration (cycling).
