Nasal pulse oximetry overestimates oxygen saturation.

J Rosenberg1, M H Pedersen.   

Abstract

Ten surgical patients were monitored with nasal and finger pulse oximetry (Nellcor N-200) for five study periods with alternating mouth and nasal breathing and switching of cables and sensors. Nasal pulse oximetry was found to overestimate arterial oxygen saturation by 4.7 (SD 1.4%) (bias and precision).
