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 measured 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 which is then sent to the laboratory for analysis.[Taken at time of the clinically indicated ABG. ]
