![]() 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).
