Brief summary

Suspicions of carbon monoxide poisoning that lead to the treatment of victims are numerous. Measurement of transcutaneous carbon monoxide saturation (SpCO) is a useful diagnostic and triage tool for victims and the toxic threshold is clearly defined for both non-smokers (SpCO\> 5%) and smokers ( SpCO\> 10%). Currently, the use of e-cigarettes is democratizing. Unfortunately, the threshold for toxic SpCO is not defined for this patient profile. The risk is treating in excess or worse than underestimating carbon monoxide poisoning in e-cigarette users who would be exposed to carbon monoxide exposure.
