Conditions
Brief summary
Pulse oximetry is commonly used in the clinical setting to titrate oxygen therapy to a target oxygen saturation range in order to avoid the risks of hypoxaemia and hyperoxaemia. The purpose of this study is to investigate the level of agreement between pulse oximeter measured oxygen saturations and arterial blood gas measured oxygen saturations (the gold standard for oxygen saturation measurement) in Australian and New Zealand hospitals.
Interventions
Participants who require an arterial blood gas (ABG) will be identified. At the time of the ABG an oximetry value (SPO2) will be measured, taken from an earlobe or finger probe. The SpO2 value will be the first value measured following visualisation of blood entering the collection vial for the ABG analysis. Only one paired ABG/SpO2 measurement will be recorded for each participant.
