Page 3: Overview
Overview The MicroCO is a hand-held battery-operated device used to measure the concentration of carbon monoxide, CO, on the breath and calculates the percentage of carboxyhemoglobin, %COHb, in the blood. It is accurate, easy to use, and has many features designed to simplify its operation. -
Page 4: Smoke Inhalation/Co Poisoning
Raised levels of carboxyhemoglobin are most commonly caused by accidental smoke inhalation/CO poisoning or cigarette smoking. The MicroCO includes a countdown timer as an aid to timing the breath holding period prior to exhalation. The results are displayed on a clear LCD display. Warning lights are provided to give an instant indication of the smoking level. -
Page 5: Cigarette Consumption
Meredith T, Vale A, Carbon monoxide poisoning British Medical Journal, 1988; 296, 77-78 Cigarette Consumption The MicroCO provides a simple screening test for cigarette consumption for use in all smoking cessation programs. Measurement of carboxyhemoglobin has been well validated as an indirect measure of cigarette consumption and is... - Page 6 Typical values for carboxyhemoglobin and expired CO in smokers and poisoning victims, together with the alarm light status, are given below: CO (ppm) %COHb Cigarette Indicator consumption 0 – 6 0 – 1 Nonsmoker Green 7 –10 1.1 – 1.6 Light smoker Amber 11 –...

Warnings and Cautions The following terms are used as follows in this manual Caution: Possibility of injury or serious damage Warning: Conditions or practices that could result in personal injury Please Note: Important information for avoiding damage to the instrument or facilitating operation of the instrument. -
Page 10: Intended Use
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 Intended Use The MicroCO is intended to measure the amount of Carbon Monoxide (CO) that can be expired from the breath. -
Page 11: Operation
CO poisoning. The MicroCO is designed for use by clinicians and health care professionals. Operation For accurate results, the CO meter should be used at room temperature. If the instrument has been stored in cool or hot conditions, allow time to reach room temperature prior to use. - Page 12 count down from 20 to 0 as an aid to timing the breath holding period. The green indicator will illuminate and the display will change to: At this time, the subject should seal their lips around the mouthpiece and exhale slowly and fully. The 20 second breath holding period is recommended to allow time for equilibration of alveolar gas.
- Page 13 Important note: Before repeating a measurement, the unit must be turned off, and the mouthpiece and adapter removed for at least one (1) minute. This is to allow re- equilibration with ambient air and to dry the surface of the sensor. Visually inspect that all moisture has evaporated from the surface of the sensor before reuse.

Page 14: Pc Connection
PC Connection The MicroCO may be connected to the serial port of a PC running COBRA (CO BReath Analysis) software. This software allows the measurements to be read by a PC and automatically entered onto a pre-defined report for subsequent printing and filing. It also allows the CO level indicators and the breath holding countdown timer to be configured to individual requirements. - Page 15 Serial Port Calibration Button Screw the control valve firmly onto the cylinder and connect the gas supply as shown below: Push the slide switch to the CO - PPM position and wait for the unit to display zero.
