Summary The accuracy of the Nellcor N‐100 pulse oximeter was evaluated in hypothermic patients (core temperature ≤ 35.0°C) after cardiac surgery. The pulse oximeter overestimated oxygen saturation in comparison to values obtained by direct in vitro oximetry with a mean bias of 0.6% saturation. The 95% predictability limits for individual measurements were ±3.9% oxygen saturation. No demonstrable loss of accuracy was caused by skin pigmentation, the concurrent administration of low doses of dopamine or vasodilators, or the intra‐operative intravascular administration of Patent Blue V dye.
