Respiratory monitoring
First Claim
1. A method of detecting a physiological parameter of a patient, comprising:
- receiving, in a sensing module, gas exhaled by a patient, the sensing module comprising;
a plurality of sensors each configured, when activated, to provide a signal indicative of a physiological parameter of the patient based on the gas; and
a sensor selector configured to cause the gas exhaled by the patient to be directed to an active sensor, the active sensor selected from the plurality of sensors.

Abstract
A patient interface in accordance with one embodiment of the present disclosure is configured to be at least partially carried by a patient and to receive gas exhaled by the patient. The patient interface includes first and second cannula tubes each having a first end and a second end, the first ends are configured to be inserted into the nostrils of a patient, the first and second cannula tubes are configured to direct exhaled gas from the patient from the first ends to said second ends. The patient interface also includes first and second sensors positioned near the second ends, and the first and second sensors are configured to provide first and second signals based upon the gas, wherein the first and second signals are indicative of a physiological parameter of the patient. The patient interface also includes a communications link configured to provide the signal to a physiological monitor.
