ABSTRACT:
An optical path is provided in the wall of an endotracheal tube to transmit light from a light source to the tracheal tissue. The same path or different path may be used to receive light reflected from the tracheal tissue to a detector for detecting the oxygen saturation of blood of a subject. The light supplied may also be directed across the gaseous medium inside the tube and received by a different optical path. The received light signal is then detected to determine the carbon dioxide concentration of the medium inside the trachea.
