"Abstract
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."
