Abstract
A gas measurement system (100) of this invention includes a housing (250) adapted to be mounted on an airway adapter, and a luminescence quenching gas measurement assembly (236) disposed in the housing. The luminescence quenching gas measurement assembly includes a source (243) disposed in a first plane, and at least one detector (238, 239) also disposed in the first plane. A filter (233) is provided over the at least one detector to passes wavelengths of radiation related to luminescence quenching and substantially blocks others. An optical shield (234) is disposed around at least a portion of the source.
