Saving'lives,'one'breath'at'a'time.'
Intended!use!
The!ToxCO®!breath!Carbon!Monoxide!monitor!and!its!accessories!are!used!in!the!screening!of!
Carbon!Monoxide!(CO)!poisoning!and!calculation!of!the!carboxyhaemoglobin!(COHb)!level.!The!
ToxCO®!breath!Carbon!Monoxide!monitor!can!be!used!by!health!professionals!in!medical!institutions!
and!emergency!medical!services!where!Carbon!Monoxide!exposure!is!suspected!for!paediatric,!
adult,!and!unconscious!patients.!
!
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!for!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!as!demonstrated!by!the!conversion!graph!in!the!appendix!on!
page!147.!The!monitor!displays!%COHb,!but!can!also!display!in!ppm!if!selected!in!the!settings.!CO!
ppm!readings!indicate!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!'the! concentration!of! carbon!monoxide! in!end-expired!air!
after!breath!holding!correlates!closely!with!carboxyhaemoglobin!concentration'3.!
Operation!of! the! ToxCO®! is! straightforward;! a! D-piece™! sampling! system! and! face!mask! sampling!
modes! allow! the! user! to! test! a! patient! independent! of! their! consciousness,! whilst! the! ambient!
sampling! mode! helps! to!safeguard! the! user! by!alerting! them! if! they! are! entering! areas! with! high!
levels!of!CO.!
A!colour!touchscreen!ensures!ease!of!operation,!and!all!readings!are!automatically!logged.!
Additionally,!all!breath!test!readings!can!be!tagged!with!a!name,!place!or!patient!ID!for!quick!
reference!at!a!later!date!and!time.!
The!ToxCO®!not!only!helps!to!reduce!unnecessary!hospital!admissions!through!instant!screening!but!
also!helps!to!save!the!lives!of!your!patients!and!your!staff,!one!breath!at!a!time.!
