1. A sensor adaptor for coupling a face mask to a gas sampling tube, comprising:
a shaft extending between a first end and a second end and defining a shaft length extending from said first end to said second end;
said shaft having a generally tubular shape including a shaft outer surface presenting a smooth cylindrical shape and a shaft inner surface opposite said shaft outer surface, and presenting a channel having a cylindrical shape, said channel being unobstructed and extending continuously from said first end to said second end for providing a direct pathway for end-tidal carbon dioxide to travel toward the gas sampling tube;
said shaft including an adaptor tip adjacent said first end for placement within the face mask and defining an adaptor length being a portion of said shaft length;
said shaft being exposed between said first end and said second end;
said sensor adaptor having no structure surrounding said shaft;
said adaptor length extending for the entirety of said shaft length;
a connector attached to said second end of said shaft for coupling said channel of said shaft to the gas sampling tube; and
said smooth cylindrical outer surface of said shaft outer surface extending substantially the entire length from said connector to said first end for providing a tight frictional press fit engagement within a circular hole of an exit port of the face mask.
