Abstract
The CO2 detector has a bottom housing attached to a top housing. The bottom housing contains a rotatable port engageable to an intubation tube and multiple parallel integral filter support ridges on a top surface of a floor. A filter pad overlies the integral filter support ridges and a baffle overlies the filter pad. The baffle has multiple parallel filter support ridges on a bottom surface cooperating with the filter support ridges integral with the bottom housing to maintain the filter pad in position. The baffle has an air flow guide on a top surface and air passages. The top housing has a port connected to a CPR bag and a clear plastic disc overlying a CO2 calorimetric indicator paper. The colorimetric indicator paper is shown through a clear plastic cover after removing backing on the indicator paper through a sealable slot.
