|Title:||Validity of pulse oximetry in detection of hypoxaemia in children: comparison of ear, thumb and toe probe placements|
|Abstract:||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 for ear probes in children [kappa = 0.70] and the lowest was for big toe probes [kappa = 0.57 and 0.28 in children and neonates respectively]|
