Methods and systems for supplying respiratory oxygen to patients when the patients are inhaling are disclosed. The methods and systems may rely on delivery devices that are selectively placed in fluid communication with either a respiration sensor or a source of oxygen. The methods and systems may actively monitor for exhalations, as well as monitor for oxygen in the oxygen source. The respiration sensor may preferably be a flow sensor.

[ What is claimed is:] [1.] A method of delivering respiratory oxygen to a patient comprising:providing an oxygen delivery system comprising an oxygen delivery device, a respiration sensor, and an oxygen source;placing the delivery device in fluid communication with the respiration sensor and monitoring variations in respiration with the respiration sensor to determine when the patient is inhaling;placing the oxygen source in fluid communication with the delivery device;delivering oxygen to the delivery device from the oxygen source when the patient is inhaling;removing the respiration sensor from fluid communication with the delivery device when delivering oxygen to the delivery device from the oxygen source;placing the respiration sensor in fluid communication with the delivery device after delivering oxygen to the delivery device from the oxygen source;monitoring variations in respiration with the respiration sensor after delivering oxygen to the delivery device from the oxygen source to determine when the patient is exhaling;resuming the monitoring of variations in respiration with the respiration sensor to determine that the patient is inhaling after determining that the patient has exhaled; andmonitoring a signal produced by the respiration sensor when it is not in fluid communication with the delivery device; andcompensating for drift in the signal generated by the respiration sensor based on the monitoring when the respiration sensor is not in fluid communication with the delivery device.
