Conducting an Ambient Test – Micro
+
™ only
The environmental air can be tested to check for CO in the environment using the Micro
+
™
Smokerlyzer. This is particularly useful in the event of a patient reporting a non-‐smoker status but
providing a breath reading of that of a smoker suggesting they have inhaled environmental CO.
This is carried out by pressing
on the screen; the Micro
+
™ will then carry out real-‐time
monitoring of the environmental air. To stop the test, press
.
Bedfont do not recommend that the environmental test alone is used as a measure of passive
smoking as the very high dispersiveness of CO at the levels involved with smoking can lead to false
negative readings.
