Multiple function airway adapter

A respiratory monitoring system, comprising:

• an airway adapter, comprising:
• a housing with a flow passage extending therethough;
• a first window positioned on top of the housing for facilitating luminescence quenching measurements of at least one substance within the flow passage;
• a luminescable material disposed in communication with the flow passage and adjacent the first window;
• a pair of second windows positioned on sides of the housing on opposite sides of the flow passage for facilitating infrared measurements of at least another substance within the flow passage;
• and
• a transducer-orienting element;
• and
• a transducer, comprising:
• an attachment feature configured to secure the transducer to the airway adapter, with the transducer-orienting element of the airway adapter defining an orientation of the transducer and a plurality of features thereof with the airway adapter such that luminescence quenching measurements are made through the first window and infrared measurements are made through the second windows.
