Abstract
The CO2 detector has a disc attached to a rim which in turn is attached to a third port on a esophageal detector housing. A baffle rises from an interior surface of the housing to slightly below an opening to the third port. A first and second port of the housing on each side of the third port are in axial alignment. The first port is attached to an elastomeric bulb and the second port is adapted to be connected to an adapter which in turn is attached to an intubation tube. A colorimetric indicator paper is shown through a clear plastic cover after removing backing on the indicator paper through the second port.
