Researchers Use Masimo ORi™, Oxygen Reserve Index, to Help Suppress Postoperative Hyperoxia in Patients Undergoing Breast Surgery

Masimo (NASDAQ: MASI) announced today the findings of an abstract recently presented at Euroanaesthesia 2020 in which Dr. Kumagai and colleagues at Iwate Medical University Hospital in Yahaba-cho, Japan investigated whether Masimo ORi™, Oxygen Reserve Index, could be used to limit the extent of postoperative hyperoxia.1 The researchers concluded that ORi helped “suppress hyperoxia, preventing hypoxia.”

ORi, available outside the U.S., is a noninvasive and continuous parameter intended to provide insight into a patient’s oxygen status during moderate hyperoxia. Enabled by the multi-wavelength rainbow® Pulse CO-Oximetry platform, ORi is provided alongside oxygen saturation (SpO2 ), a clinically proven Masimo SET® pulse oximetry measurement.

Noting that postoperative hyperoxia is associated with various adverse outcomes—including “acute lung injury, increased hospital mortality, and worse outcomes in patients with ischemic stroke”—the researchers sought to determine whether a noninvasive, continuous parameter could help clinicians assess the appropriate amount of supplemental oxygen to administer to surgical patients, so as to limit hyperoxia post-surgery. They divided 50 patients scheduled for breast surgery into a group receiving ORi-based oxygen treatment (group O) and a control group that received conventional postoperative oxygen treatment (group C). In group C, after extubation, oxygen was administered at a fixed rate (4 L/min); in group O, oxygen was administered at 4 L/min but decreased by 0.5 L/min if ORi > 0.00, until ORi was 0.00 for 30 minutes continuously. Blood gas analysis was performed at various intervals. Hyperoxia was defined as partial pressure of arterial oxygen (PaO2 ) > 120 mmHg, and hypoxia as oxygen saturation (SpO2 ) ≤ 94% for more than 1 minute.

The researchers found that PaO2 was significantly lower in the ORi group both before patients left the PACU (mean 117.3 mmHg [one standard deviation 26.8 mmHg] in group O vs. 170.0 mmHg [42.8 mmHg] in group C) and the morning after surgery (107.5 mmHg [16.5 mmHg] in group O vs. 157.1 mmHg [28.4 mmHg] in group C); p < 0.01. No patients had hypoxia.

The researchers concluded, “Determining postoperative supplemental oxygen amount using ORi can noninvasively suppress hyperoxia, preventing hypoxia.”

ORi has not received FDA 510(k) clearance and is not available for sale in the United States.

About Masimo

Masimo (NASDAQ: MASI) is a global medical technology company that develops and produces a wide array of industry-leading monitoring technologies, including innovative measurements, sensors, patient monitors, and automation and connectivity solutions. Our mission is to improve patient outcomes and reduce the cost of care. Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies.2 Masimo SET® has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,3 improve CCHD screening in newborns,4 and, when used for continuous monitoring with Masimo Patient SafetyNet™ in post-surgical wards, reduce rapid response team activations, ICU transfers, and costs5-8 Masimo SET® is estimated to be used on more than 200 million patients in leading hospitals and other healthcare settings around the world,9 and is the primary pulse oximetry at 9 of the top 10 hospitals according to the 2020-21 U.S. News and World Report Best Hospitals Honor Roll.10 Masimo continues to refine SET® and in 2018, announced that SpO2 accuracy on RD SET® sensors during conditions of motion has been significantly improved, providing clinicians with even greater confidence that the SpO2 values they rely on accurately reflect a patient’s physiological status. In 2005, Masimo introduced rainbow® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb® ), oxygen content (SpOC™), carboxyhemoglobin (SpCO® ), methemoglobin (SpMet® ), Pleth Variability Index (PVi® ), RPVi™ (rainbow® PVi), and Oxygen Reserve Index (ORi™). In 2013, Masimo introduced the Root® Patient Monitoring and Connectivity Platform, built from the ground up to be as flexible and expandable as possible to facilitate the addition of other Masimo and third-party monitoring technologies; key Masimo additions include Next Generation SedLine® Brain Function Monitoring, O3® Regional Oximetry, and ISA™ Capnography with NomoLine® sampling lines. Masimo’s family of continuous and spot-check monitoring Pulse CO-Oximeters® includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology, such as Radius-7® and Radius PPG™, portable devices like Rad-67™, fingertip pulse oximeters like MightySat® Rx, and devices available for use both in the hospital and at home, such as Rad-97® . Masimo hospital automation and connectivity solutions are centered around the Masimo Hospital Automation™ platform, and include Iris Gateway® , Patient SafetyNet, Replica™, Halo ION™, UniView™, UniView: 60™, and Masimo SafetyNet™.
