Abstract:
1. A method for ventilating a patient with a ventilator comprising: receiving a target tidal volume and a set positive end expiratory pressure (PEEP) by a ventilator; receiving a set minimum inspiration pressure by the ventilator; receiving at least two of a set inspiration time, a set exhalation time, a set inspiration time to expiration time ratio (I:E ratio), and a set respiratory rate by the ventilator; delivering a first inspiration pressure to a patient in a first breath; calculating a revised effective pressure for delivery to the patient to achieve the target tidal volume based on measurements taken from the first breath indicative of a tidal volume delivered to the patient in the first breath; comparing the calculated revised effective pressure to the received set minimum inspiration pressure; delivering a second inspiration pressure with the ventilator during a second breath to the patient, the second inspiration pressure is determined based on the calculated revised effective pressure and the step of comparing the calculated revised effective pressure to the received set minimum inspiration pressure; delivering the PEEP during exhalation with the ventilator; delivering an I:E ratio of greater than 4:1 during each breath without requiring a clinician to enter both a set PEEP delivering a spontaneous breath in response to a patient initiated trigger during inspiration above the delivered second inspiration pressure and during expiration above the delivered PEEP.
