“…In the 1990s, several signal processing techniques were incorporated in pulse oximeters in an attempt to reduce motion artifact [ 34 – 38 ]. One such technique is Masimo signal extraction technology (SET™) [ 39 ]. During motion and hypoxia, the Masimo SET oximeter performed better than the Agilent Viridia 24C (Agilent Technologies, Santa Clara, CA, USA), the Datex-Ohmeda 3740 (Datex-Ohmeda, Madison, WI, USA), and the Nellcor N-395 (Covidien Corporation, Dublin, Ireland) oximeters [ 34 ].…”

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.

“…An innovative technologic approach, termed Masimo signal extraction technology (Masimo SET; prototype), was recently introduced to extract the true signal from artifact due to noise and low perfusion. 10 This technique incorporates new algorithms for processing the pulse oximeter's red and infrared light signals that enable the noise component, which is common to the two wavelengths, to be measured and subtracted. When tested in healthy volunteers dur-ing standardized motion, Masimo SET exhibited much lower error rates (defined as percentage of time that the oximeter error exceeded 5, 7, and 10%) and dropout rates (defined as the percentage of time that the oximeter provided no Spo 2 data) than did the Nellcor N-200 and Nellcor N-3000 oximeters (Nellcor Puritan-Bennett Corp; Pleasanton, CA).…”
