1. A method for automatically controlling blood oxygen saturation in a patient, comprising:
- delivering a gas mixture to the patient;
monitoring at least one physiologic parameter of the patient;
determining a physiologic delay between delivering the gas mixture and detection of a corresponding response to delivering the gas mixture; and
automatically controlling the delivery of the gas mixture based at least in part upon the delay detected and based on a value of the physiologic parameter.

Abstract
Embodiments of the present invention relate to a system and method for automatically controlling a physiologic parameter of a patient. Specifically, embodiments of the present invention include delivering a gas mixture to the patient and monitoring at least one physiologic parameter of the patient, detecting whether a physiologic delay exists between delivering the gas mixture and detection of a corresponding response to delivering the gas mixture, and automatically controlling the delivery of the gas mixture based on whether the delay is detected and based on a value of the physiologic parameter.
