  • Patient ventilator system and method
    Patent number: 11383055
    Abstract: A patient ventilator system includes a patient delivery circuit having an inspiratory section that delivers an inspiratory gas flow to a patient and an expiratory section that receives expiratory gas flow from the patient, wherein a bidirectional blower motor drives the inspiratory gas flow in the inspiratory section and controls the expiratory gas flow in the expiratory section. A flow sensor measures gas flow rate between the bidirectional blower motor and the patient delivery circuit. A four quadrant controller is configured to control speed and direction of the bi-directional blower motor based on the measured flow rate so as to effectuate ventilation for the patient.
