The MicroCO is intended to measure the amount of Carbon Monoxide
(CO) that can be expired from the breath. The expired CO is measured
in parts per million and is used to calculate the percentage of
carboxyhemoglobin, %COHb, in the blood.
The MicroCO is used in smoking cessation clinics, physician offices
emergency departments, and by the fire-fighting services. In smoking
cessation clinics it is used for instructional purposes and to check on
the client's progress and compliance. General practitioners, Emergency
room personal and the fire-fighting services can use the instrument to
quickly assess the level of suspected CO poisoning.
The MicroCO is designed for use by clinicians and health care
professionals.
