Psupport and PEEP levels The patient establishes the rate inspiratory flow and inspiratory time The tidal volume is determined by the pressure lung characteristics and patient effort PSVPro uses an inspiration termination level that establishes when the ventilator will stop the pressure supported breath and cycle to the expiratory phase The inspiration termination level is user adjustable from 596 to 5096 This parameter sets the percent of the peak inspiratory flow that the ventilator uses to end the inspiratory phase of the breath and to cycle into the expiratory phase If the inspiration termination is set to 3096 then the ventilator will stop inspiration when the flow decelerates to a level equal to 3096 of the measured peak inspiratory flow The lower the setting the longer the inspiratory time and conversely the higher the setting the shorter the inspiratory phase An apnea backup mode is provided in the event the patient stops breathing When setting this mode the clinician adjusts the inspiratory pressure Pinsp respiratory rate and the inspiratory time Tinsp As long as the patient is triggering the ventilator and the apnea alarm does not activate the patient will get pressure supported breaths and the ventilator will not deliver machine breaths If the patient stops triggering the ventilator for the set apnea delay time the apnea alarm will activate and the ventilator will automatically switch to the backup mode that i
