ABSTRACT:
A ventilator supplies a plurality of volumes of fluid to a patient during a like plurality of inhalations by the patient. Each volume of fluid is supplied at an inspiratory positive airway pressure during a corresponding inhalation by the patient. A volume of fluid received by the patient is determined for each of the plurality of inhalations by the patient and an average volume of fluid received by the patient during each of the plurality of inhalations is determined. The average volume of fluid received by the patient during each inhalation is compared to a predetermined target volume and the inspiratory positive airway pressure each volume of fluid is supplied to the patient is adjusted as a function of the comparison.
