The researchers found that the combination of ORi and standard of care oxygen saturation (SpO2) monitoring reduced hyperoxemia compared to SpO2 monitoring alone.1\nThis press release features multimedia.

Enabled by the multi-wavelength rainbow® Pulse CO-Oximetry platform, ORi is provided alongside SpO2 measured by clinically proven Masimo SET® pulse oximetry.\n\nNoting that the use of supplemental oxygen during general surgery increases the risk of hyperoxemia, the researchers sought to evaluate whether noninvasive, continuous ORi might improve clinicians’ ability to detect hyperoxemia, since SpO2 monitoring alone cannot monitor beyond 100% saturation, and since arterial blood gas analysis has the disadvantages of being invasive and giving intermittent, delayed results. To test their hypothesis, the researchers randomly allocated 62 adult patients scheduled for elective laparoscopic gastrectomy into two groups, one whose fraction of inspired oxygen (FiO2) during anesthesia was guided by ORi and SpO2 monitoring (the ORi-SpO2 group, n=30), and a control group whose FiO2 was guided by SpO2 monitoring alone (the SpO2 group, n=32). Patients in both groups were monitored with Masimo Radical-7® Pulse CO-Oximeters® with rainbow® sensors. In addition to Masimo ORi and SET® SpO2, Masimo PVi® (pleth variability index) was monitored as part of goal-directed fluid management.\n\nIn the ORi-SpO2 group, FiO2 was adjusted to maintain ORi > 0 and \nThe researchers found that one hour after s...
