Pulse
oximetry is universally used for monitoring patients in the critical care
setting. This article updates the review on pulse oximetry that was published
in 1999 in Critical Care. A summary of the recently developed multiwavelength
pulse oximeters and their ability in detecting dyshemoglobins is provided. The
impact of the latest signal processing techniques and reflectance technology on
improving the performance of pulse oximeters during motion artifact and low perfusion
conditions is critically examined. Finally, data regarding the effect of pulse
oximetry on patient outcome are discussed.
