Abstract: A gas analyzer for measuring a respiratory gas component includes an emitter that transmits infrared (IR) radiation through a measurement chamber containing respiration gas, and at least one IR detector configured to receive at least a portion of the IR radiation transmitted through the measurement chamber and to generate radiation measurement data based on the received IR radiation. A light source is configured to emit light onto a color indicator, wherein the color indicator is one of a predefined set of colors. A color detector is configured to detect light reflected by a color indicator so as to identify color information. The controllers configured to determine a respiratory gas component concentration within the measurement chamber based on the color information and the radiation measurement data.

Abstract: An airway adaptor providing a measurement chamber for gas measurement by a mainstream gas analyzer includes a body having a first end and a second end and configured to connect in a ventilation circuit carrying ventilation gas to and from a patient. The body forms a primary path that includes the measurement chamber and is configured to allow ventilation gas to pass between the first end and the second end and at least one secondary path separated from the primary path and located on an outer perimeter of the primary path. The at least one secondary path is configured to contain liquid away from the measurement chamber.

Abstract: A gas analyzer for measuring a respiratory gas component includes an emitter that emits two different wavelengths of infrared (IR) radiation in to a measurement chamber containing a respiratory gas, wherein the two different wavelengths include a first IR wavelength and a second IR wavelength. The gas analyzer further includes a first IR detector, a second IR detector, and a beam splitter. The beam splitter is configured to receive the two different wavelengths of radiation emitted by the emitter and to split the two wavelengths of radiation so as to reflect the first IR wavelength to the first IR detector and reflect the second IR wavelength to the second IR detector.
