intended!for!multi-patient!use!by!healthcare!professionals!in!smoking!cessation!programmes!and!

Introduction!!
Carbon!monoxide!(CO)!is!a!toxic,!odourless,!colourless!and!tasteless!gas1.!It!is!formed!by!the!
incomplete!combustion!of!organic!material!at!high!temperatures,!with!an!insufficient!oxygen!supply.!!
When!inhaled,!CO!displaces!oxygen!in!the!bloodstream!to!form!carboxyhaemoglobin!(COHb).!This!
starves!body!tissue!of!oxygen!restricting!the!body’s!performance!and!causing!health!implications2.!
CO!can!remain!in!the!bloodstream!for!up!to!24!hours,!depending!on!factors!such!as!physical!activity,!
sex,!and!inhalation!intensity.!The!half-life!is!about!5!hours3.!!
CO!(ppm),!carboxyhaemoglobin!(%COHb)!and!foetal!carboxyhaemoglobin!(%FCOHb)!correlation:!
Breath!carbon!monoxide!is!measured!in!parts!per!million!(ppm)!and!blood!carboxyhaemoglobin!is!
measured!in!percentages!(%COHb!and!%FCOHb)4.!The!three!are!compatible!and!convertible:!the!
ppm!CO!reading!relates!to!gas!in!the!lungs!and!on!the!breath!(i.e.!the!amount!of!poisonous!CO!that!
