The accuracy of the Ohmeda Biox 3700 pulse oximeter was evaluated in 10 paediatric patients, deliberately surface cooled to 25 degrees C in preparation for cardiac surgery, by comparing the arterial oxygen saturation results obtained from an Ohmeda Biox 3700 and a Radiometer OSM-2 Hemoximeter. Though there was a good correlation between the two series of results, the arterial oxygen saturation was over-estimated by the pulse oximeter compared to the OSM-2 Hemoximeter in the temperature range 36 degrees to 30 degrees C and under-estimated below 30 degrees C. These differences were greatest when the initial saturations were low.
