Ease of use is key in a busy smoking cessation clinic – from a single breath the results are instantly displayed in parts per million (PPM) and % carboxyhaemoglobin (%COHb), clear visual guidance is also provided with coloured red, yellow and green indicators dependent on the concentration of exhaled carbon monoxide, indicating if the person is a non-smoker, light smoker, or heavy smoker.
Additionally the CO Check Pro is also capable of detecting environmental CO levels. When the Environmental Capture is enabled, background CO levels are taken into account when carrying out a breath test. If the background levels are 10ppm for example, then when the person is taking a breath test this background reading of 10ppm will be taken into account, allowing any possible environmental exposure to be clearly identified. Environmental levels are displayed in PPM.
It is widely accepted and acknowledged a non-smoker will perform a test and will display a level of 6ppm or less. A light smoker will perform a test and have a reading between 7 – 10ppm. A smoker will perform a test and have a reading of between 11 – 20ppm and a heavy smoker will display a reading of 21ppm or more.
