2. Diagnosis of CO poisoning.
3. Age under 16 years.

- Primary Outcome Measures
Name Time Method SpO2, measured by pulse oximetry at the same time an ABG is performed.[The SpO2 value will be the first value displayed by the pulse oximeter following visualisation of blood entering the collection vial for the ABG analysis.];SaO2, measured by ABG (while the pulse oximeter is in place).<br>ABG is assessed by means of a blood sample taken from an artery.[Taken at time of the clinically indicated ABG.]
- Secondary Outcome Measures
