Validity of pulse oximetry in detection of hypoxaemia in children: comparison of ear, thumb and toe probe placements (2010)This study of paediatric intensive care patients aimed to determine where pulse oximetry probes should be placed to obtain the most accurate and reliable readings of peripheral oxygen saturation [SpO]. Using arterial blood gas analysis [SaO] as the gold standard and SpO < 92% and SaO < 90% as indicators of hypoxaemia, negative predictive values of SpO were 96%, 98% and 98% at the ear, thumb and big toe respectively in 110 children, and 93% at all 3 sites in 90 neonates. The highest clinical agreement between SaO and SpO was ...
