Overview The BabyCO meter is a hand held battery operated device used to measure the concentration of carbon monoxide, CO, on the breath and calculates the percentage of carboxyhaemoglobin, FCOHb, in the foetus’ blood. It is used in smoking cessation clinics, GP’s surgeries, and antenatal clinics. In smoking cessation clinics it is used for instructional purposes and to check on the clients progress and compliance. It is accurate, easy to use, and has many features designed to simplify its operation.
Warning lights are provided to give an instant indication of the smoking level. The warning light levels are user adjustable when the unit is connected to a PC running COBRA software. References 1. Gomez C, Berlin I, Marquis P, Delcroix M. Expired air carbon monoxide concentration in mothers and their spouses above 5 ppm is associated with decreased foetal growth.
Please note that some urban areas may have high environmental levels of CO. This can cause a rise in exhaled CO of a few ppm above that which is normally present on the breath. In these cases it is possible for a non-smoker to appear at the bottom of the ‘light smoker’ range (7 – 10 ppm). The above table applies when the unit is measuring expired CO with the switch in middle position.
Package Contents The BabyCO meter is supplied with a carrying case containing the following items: 1. BabyCO meter (Cat No. 36-BC01-STK) 2. 22 mm mouthpiece adapter (Box of 10 Cat No.36-PSA2000) 3. 22 mm reducing connector for calibration (Cat No.36-MEC1007) 4. PP3 Battery (Cat No.36-BAT1002) 5. Disposable mouthpieces (Box 250 Cat No.36-PSA1200) 6. Calibration tool (Cat No.
Operation For accurate results the BabyCO 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. Install the PP3 battery by sliding open the battery cover, clipping the battery in place and replacing the cover. Insert the mouthpiece adapter into the BabyCO meter and then insert a disposable mouthpiece into the adapter. Turn the unit on by pushing the slide switch to the middle position (CO).
ppm CO Provided the subject is not too distressed after seeing the breath CO measurement, then the calculated foetal carboxyhemaglobin level may be displayed by pushing the slide switch to the top position (FCOHb): % FCOHb The unit must not be used, however, for one second after the unit is first switched on i.e. before the display shows ‘BLOW’. Expired alveolar gas is then entrapped between sensor and mouthpiece valve. The display reading will rise to a plateau over the course of several seconds.
If the unit is switched on again too quickly after use there may be a response to residual expired carbon monoxide from the previous test. In this case the display will show: If this is displayed then turn the unit off, remove the mouthpiece adapter, and expose to ambient air for 2 minutes before repeating the test. Note: If this warning appears again after following the above procedure then turn off and leave the sensor exposed to ambient air for a further 3 minutes.
Note: the BabyCO meter should only be connected to a computer that is manufactured in accordance with EN60950 1992/1993 – ‘Safety of Information Technology Equipment including Electrical Business Equipment’. Calibration Calibration will remain stable to within 2% over one month and typically to within 10% over 6 months. CareFusion supplies calibration gas (20ppm CO in air) and recommends that the unit be recalibrated on a 6 monthly basis. See page 15 for calibration accessories.
Plastic Tubing Control Valve Flow Indicator Reducing connector for for Calibration 20 ppm carbon monoxide in air The plastic tubing supplied with the gas should be pushed firmly over the reducing connector. Slowly turn the control knob anti-clockwise until the ball in the flow indicator is between the two marks. This will then supply a gas flow of approximately 0.25 l/min.
the meter does not read 20ppm use the calibration tool to push the calibration switch. The unit will then beep 3 times, store the new calibration value, and display the following: The gas supply should then be turned off. If the signal from the CO sensor is too low a new calibration value will not be stored and the display will show: The most likely cause for this is an expired cell but may also be caused by depressing the calibration switch with no gas applied.
Sensor life ranges from 2 to 5 years and depends upon both the amount of exposure to CO and other gases, particularly solvents such as alcohol and cleaning fluids. If the signal from the CO sensor is too high, a new calibration value will not be stored and the following will be displayed when calibration is attempted: The most likely cause for this is using an incorrect concentration of calibration gas.
Battery Life Battery life is approximately 30 hours of continuous use. When the battery has approximately 1 hour of useful life left the alarm will sound momentarily after the unit is first switched on and the following message will be displayed: When the battery has completely expired the above will be displayed continuously and the battery must be replaced. Note: Please remove the battery if the meter is likely to be unused for more than a month.
When this occurs, the BabyCO meter must be returned to CareFusion, or an authorised agent, for battery replacement. Cleaning The mouthpiece adapter may be cleaned using a mild detergent solution or replaced if there is risk of contamination. Exposed surfaces of the meter, other than the sensor surface, may be wiped with a clean, damp cloth. It is recommended that this procedure is performed after each use and all used cardboard mouthpieces discarded.
