May 11, 2021 healthcaretechnology Study Investigates the Ability of Masimo O3® to Aid in Monitoring Septic Shock ICU Patients and Predicting Mortality Masimo (NASDAQ: MASI) announced today the findings of a study published in the Journal of Anesthesia & Clinical Research in which Dr. Debdipta Das and colleagues at Medical College Kolkata in India evaluated the utility of Masimo O3® Regional Oximetry to aid in monitoring septic shock patients admitted to the ICU.1 O3, available on the Masimo Root® Patient Monitoring and Connectivity Platform, uses noninvasive near-infrared spectroscopy (NIRS) to enable monitoring of regional oxygen saturation (rSO2) in the region of interest, such as the brain or cerebral tissue (CrSO2). The researchers found that O3 trends correlated significantly with a variety of other hemodynamic variables and lactic acid levels commonly used in the monitoring of septic shock patients. They also found rSO2 values differed significantly between patients who survived and those who did not, suggesting it may have value as a predictor of mortality in septic shock patients.
