  • Rapid anesthesia emergence system using closed-loop PCO.sub.2 control
    Patent number: 5320093
    Abstract: A system is disclosed for rapidly restoring ventilatory drive to an anesthetized patient after surgery. The end-expired carbon dioxide partial pressure is used as feedback to determine the amount of CO.sub.2 to be added to the inspired breathing mixture of the patient's breathing circuit. The CO.sub.2 added to the patient's breathing circuit increases CO.sub.2 within the blood stream to a level sufficient to stimulate the central ventilatory center in the brain, thereby rapidly restoring ventilatory drive to the patient.
