—The study by Drs Cobb and Etzel¹ on unintentional carbon monoxide related deaths represents a meaningful undertaking.

However, they are incorrect in stating that "detection of the gas requires expensive equipment" and in their implication that such devices are unavailable. After more than 18 months of research and development, we have in production a small (10.1x5x3.7-cm) detector with visual and audible alarm powered by 12-V DC or 110-V AC, aptly named AIR-CHEK.

Since hemoglobin has an affinity for carbon monoxide 250 times greater than for oxygen, the detector has timing factors that produce a warning sound when the air concentration of carbon monoxide is 50 ppm for 6 hours or 200 ppm for 1.5 hours, or when the level reaches 400 ppm at any time. The detector is priced at $79.95 and is made possible by new semiconductor and printed circuit-board technology.

It is hoped that . . . [Full Text PDF of this Article]
