The nose sensor can include an emitter and a detector. The detector is configured to generate a signal when detecting light attenuated by the nose tissue of the patient. An output measurement of the physiological parameter can be determined based on the signals generated by the detector. The nose sensor can include an inner prong and an outer prong to assist the nose sensor in securing to a patient's nose. The detector can be coupled to an inner post of the inner prong and can be configured to secure to an interior or exterior portion of the patient's nose. ## Claims ### Claim 1 A noninvasive physiological monitoring device configured to be secured to a nose of a user and measure/monitor one or more physiological parameters, the noninvasive physiological monitoring device comprising: a first prong configured to be positioned on an inner side of the user's nose;
