II. Introduction – CareFusion USA
The Smoke Check is based on an electrochemical fuel cell sensor,
which works through the reaction of carbon monoxide (CO) with an
electrolyte at one electrode, and oxygen (from ambient air) at the
other. This reaction generates an electrical current proportional to CO
concentration. Output from the sensor is monitored by a
microprocessor, which detects and displays peak expired
concentrations of alveolar gas. High levels of expired CO indicate
raised levels of carboxyhaemoglobin, most commonly caused by
cigarette smoking.
The results are displayed in four ranges on a clear LCD display.
Warning lights are provided to give an instant indication of the
smoking level. A particular feature of the Smoke Check is its stability
