When you connect the MicroCO to other equipment,
always make sure that the whole combination complies with the
international safety standard IEC 60601-1 for medical electrical
systems. During measurements, connect the MicroCO only to
computers that comply with IEC 60601-1 / ANSI/AAMI ES60601-
1:2005 / CAN/CSA-C22.2 No. 60601-1:14.
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 carboxyhaemoglobin, %COHb, in the blood.
The MicroCO is used in smoking cessation clinics, GP's surgeries,
accident and 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, A&E clinicians 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.
For accurate results the CO meter should be used at room
temperature. If the instrument has been stored in cool or hot
conditions then allow time to reach room temperature prior to use
