Abstract: A method for automatically controlling ventilation of a patient includes receiving a target expiratory CO2 concentration, measuring an actual expiratory CO2, and comparing the actual expiratory CO2 concentration to the target expiratory CO2. A ventilation rate for the patient is then calculated based on the comparison of the actual expiratory CO2 concentration and the target expiratory CO2 in order to maintain the actual expiratory CO2 within a predetermined range of the target expiratory CO2. The patient is then automatically ventilated based on the calculated ventilation rate.

Abstract: A method and system for monitoring a patient under anesthesia involves determining a drug sensitivity index for the patient. Patient demographic information and amount of anesthetic information is obtained, wherein the amount of anesthetic information includes each drug administered to the patient and the dose amount thereof. An effect site concentration, which represents a total anesthetic concentration in a patient's brain, is then estimated based on the anesthetic information. An expected response is determined based on the demographic information and the effect site concentration. Physiological data is recorded from sensors mounted to a patient, and a depth of anesthesia is determined based on physiological data. An actual response of the patient is then determined based on the depth of anesthesia and the effect site concentration. Finally, a drug sensitivity index is determined for the patient by comparing the expected response to the actual response.
