Masimo has announced FDA 510(k) clearance for the pediatric indication for O3 regional oximetry with the O3 pediatric sensor. Regional oximetry, also referred to as tissue or cerebral oximetry, may help clinicians monitor cerebral oxygenation in situations in which peripheral pulse oximetry alone may not be fully indicative of the oxygen in the brain. With the clearance of the O3 pediatric sensor, O3 regional oximetry monitoring, which was already available for adult patients in the United States, is now also available for pediatric patients weighing more than 5 kg (11 lbs.) and less than 40 kg (88 lbs.).
 
O3 regional oximetry uses near-infrared spectroscopy (NIRS) to continuously monitor absolute and trended regional tissue oxygen saturation (rSO₂) in the cerebral region. Early detection and correction of imbalances in oxygen delivery to the brain are important tools in helping patients avoid postoperative morbidity and adverse outcomes.¹
 
“O3 regional oximetry provides access to valuable data about cerebral oxygen saturation,” said Joe Kiani, Founder and CEO of Masimo. “With adult and pediatric trend accuracy of 3 percent and absolute accuracy of 4 percent and 5 percent on adults and pediatrics respectively,² without controlling CO₂, Masimo O3 should help clinicians build a better picture of brain oxygenation—and hopefully better outcomes for all of their patients, including pediatrics as young as three-months old.²”
 
In addition, Masimo O3 regional oximetry and SedLine brain function monitoring are both available on a single platform, Masimo Root—opening up a path to better understanding of the brain.
