摘要：
We describe a capnometer for detecting a concentration of a component in a gas, wherein said gas is inhaled and/or exhaled by a patient, said capnometer comprising: an air flow region through which said gas passes to and/or from said patients lung a mid-IR semiconductor emitter configured to provide IR light at a wavelength in the range 3-5 µm a mid-IR semiconductor detector to detect said IR light a reflector to reflect said IR light emitted by said emitter wherein said emitter, said detector and said reflector are arranged such that said IR light emitted by said emitter passes through said air flow region via said reflector to said detector.
