  • Intermittent mandatory assisted ventilation system for positive pressure breathing apparatus
    Patent number: 3976064
    Abstract: A respiration system for weaning patients from a respirator wherein a mandatory ventilation assist is provided to the patient upon inspiration after predetermined time intervals. A sensitivity mechanism for sensing inspiration by the patient and for actuating the mandatory ventilation assist is desensitized or rendered inoperative during a predetermined time interval in which the patient will be required to breathe normally without assist. At the end of the time interval, the sensitivity mechanism is again rendered operative for the mandatory ventilation assist. In the event that the patient does not trigger the sensitivity mechanism within a second given period of time following the end of the time interval, a mandatory ventilation assist is provided.
