ABSTRACT:
Ventilator having an inhalation phase and an exhalation phase in its operative cycle for use with a source of gas under pressure. A demand flow accelerator is responsive to the pressure of the gases in a breathing head assembly and provides additional gases to the breathing head assembly when the pressure of the gases in the breathing head assembly falls below a predetermined pressure. A sensor is also provided responsive to the pressure of the gases in the breathing head assembly for supplying gases to the breathing head assembly when the pressure of the gases in the breathing head assembly falls below a predetermined value to cause the patient to exhale against a substantially constant positive airway pressure. An additional sensor is also provided which is sensitive to the airway pressure being sensed for bleeding gases from the breathing circuit when pressure greater than a predetermined pressure are reached. Lock-out means is provided for locking out an inspiratory phase which exceeds a predetermined time. Starting means is provided for ensuring that the ventilator will be switched to an expiratory phase before an inspiratory phase is initiated.
