Intended!Use!
!
The! ToxCO®!is! a! breath! carbon! monoxide! monitor! intended! for! multi-patient! use! by! healthcare!
professionals!in!a!healthcare!environment,!to!determine!levels!of!carbon!monoxide!(CO)!poisoning.!
!
Introduction!!
!
Carbon!monoxide!is!a!toxic,!odourless,!colourless,!tasteless!gas1.!It!is!formed!from!incomplete!
combustion!of!organic!material!at!high!temperatures!with!an!insufficient!oxygen!supply3.!When!
inhaled,!CO!competes!successfully!with!oxygen!in!the!bloodstream!to!form!carboxyhaemoglobin!
(COHb).!This!starves!the!body!tissues!of!the!oxygen!vital!to!repair,!regeneration!and!general!living.!
CO!can!remain!in!the!bloodstream!for!up!to!24!hours,!depending!on!a!range!of!factors!including!
physical!activity,!gender!and!inhalation!intensity10.!The!half-life!is!about!5!hours!with!no!treatment!
(normal!environmental!conditions),!1.5!hours!if!100%!oxygen!is!given!and!0.58!hours!if!hyperbaric!
oxygenation!at!100%!oxygen!is!given8.!
Breath!carbon!monoxide!is!measured!in!parts!per!million!(ppm)!and!blood!carboxyhaemoglobin!in!
percentages!(%COHb).!The!two!measurements!are!compatible!and!convertible,!CO!relating!to!
lung/breath!and!COHb!to!blood!gas.!The!monitor!displays!%COHb!and!ppm!using!the!conversion!
graph!in!the!appendix!on!page!147.!CO!ppm!readings!demonstrate!the!levels!of!poisonous!inhaled!
CO,!while!the!%COHb!reading!shows!the!percentage!of!vital!oxygen!that!has!been!replaced!in!the!
bloodstream7.!!
Clinical! research! has! demonstrated! that! a! useful! relationship! between! carbon! monoxide! and!
carboxyhaemoglobin!is!obtained!after!a!short!period!of!breath!holding!by!the!person,!although!this!
is!not!essential!when!assisting!a!diagnosis3.!!
Operation!of!the!ToxCO®!instrument!is!straightforward;!a!D-piece!sampling!system!enables!!
end-expired!breath!to!be!sampled!easily!and!hygienically,!whilst!using!SteriBreath™!mouthpieces.!
Alternatively,!for!unconscious!or!unwilling!patients,!a!facemask!can!be!used.!!
