A method for controlling the delivery of a breathing gas to a patient. The method comprises: delivering a flow of breathing gas to a patient, the breathing gas having a breathing gas flowrate and a fraction of inspired oxygen; measuring an oxygen saturation level of the patient; determining a respiratory rate of the patient; automatically adjusting the fraction of inspired oxygen of the breathing gas based on the measured oxygen saturation level of the patient and a breathing gas flowrate set-point; and automatically adjusting the breathing gas flowrate set-point based on the determined respiratory rate of the patient.

A method is provided for detecting the presence of an anomaly within an observed physical signal. The observed signal includes an addition of a physical disturbance signal and a reference signal. The anomaly is relative to a change in the behavior of the reference signal compared with a first tolerance value. Such a method includes: determining a time span having at least one moment of interest; detecting the presence of the anomaly within the observed physical signal during the time span by conducting a hypothesis test using the first tolerance value, a first rate of tolerated false alarms, and data obtained from processing the observed signal.

A method for administering a gas containing oxygen to a patient. The method includes: measuring an oxygen-dependent physiological parameter in the patient; determining an optimal gas delivery parameter based on the oxygen-dependent physiological parameter; and administering the gas to the patient in accordance with the optimal gas delivery parameter. In some embodiment of the invention, the method also includes monitoring the oxygen-dependent physiological parameter.
