1. A neonatal colorimetric carbon dioxide detector, the neonatal colorimetric carbon dioxide detector formed to insert into an airway circuit, the neonatal colorimetric carbon dioxide detector comprising:

  • an enclosure having a patient orifice in fluid communication with a patient'"'"'s airway and a respiration equipment orifice, the respiration equipment orifice in fluid communication with the patient orifice, the respiration equipment orifice being partially occluded thereby reducing an internal volume of the respiration equipment orifice, the patient orifice overlaps and is offset with respect to the respiration equipment orifice; and

    a colorimetric membrane held within the enclosure and visible from outside of the enclosure, the colorimetric membrane in fluid communication with the patient orifice such that the colorimetric membrane is exposed to exhalation gas from the patient orifice before the exhalation gas exits through the respiration equipment orifice.
