Methods, systems, and software are disclosed for simulating and controlling anesthesia delivery and for implementing automatic closed-loop anesthesia with an inhaled anesthetic agent. The methods involve using a physiological simulation to forward calculate the effects of an inhaled anesthetic agent, and searching for gas administration characteristics, such as fresh gas flow rates and anesthetic concentrations or partial pressures, that will achieve a desired physiological anesthetic concentration or effect with minimal use of anesthetic agent and minimal fresh gas flow rate. |
