NEUCHATEL, Switzerland–(BUSINESS WIRE)–Jan 9, 2023–
Fields (NASDAQ: MASI) today announced the results of an im American Journal of Emergency Medicine published prospective study in which Dr. Zohair Ahmed Ali Al Aseri and his colleagues from King Saud University Medical City and Dar Al Uloom University (Riyadh, Saudi Arabia) evaluated the performance of noninvasive hemoglobin spot check measurement with Masimo SpHb ® in emergency room patients. Researchers concluded that SpHb offers “acceptable accuracy and excellent correlation” with their invasive laboratory measurements and represents a “simple, rapid, practical, inexpensive, and accurate solution for Hb testing in the emergency room.” 1

Given that while invasive hemoglobin measurement is an important step in treating blood loss, it also has disadvantages such as: For example, “the consumption of valuable time, phlebotomy-related anemia, pain, infection, and greater demands on staff and equipment,” the study authors wanted to find out if a noninvasive method could provide similarly accurate results while mitigating some of these factors. To compare noninvasive and invasive measurements, they enrolled 650 patients (age > 14 years) who attended the emergency departments of two hospitals at King Saud University Medical City between March and May 2022 and required a complete blood count. Hemoglobin was measured non-invasively (SpHb) using the Masimo Rad-67 ® Pulse CO-Oximeter ® with the DCI ® -mini finger sensor. Blood samples were collected at the same time and analyzed at the time of collection (LabHb) using the UniCel DxH 800 Coulter Cellular Analysis System automated analyzer.
The researchers found a “highly significant correlation” between SpHb and LabHb (Pearson’s correlation coefficient = 0.812, p<0.01). Bland-Altman analysis revealed a low mean error of 0.146 g/dL ± 1.39 g/dL, with moderate limits of agreement (-2.58 and 2.87 g/dL) and a margin of error (95% confidence interval) of 2 .7 g/dL.
Scientists concluded that “noninvasive hemoglobin (SpHb) measurement has acceptable accuracy and excellent correlation with LabHb and provides a simple, rapid, practical, inexpensive, and accurate solution for Hb measurement in the emergency department. Further research is needed to examine the effects on patient outcomes, blood transfusion, and time and cost efficiencies.”
SpHb monitoring is not intended to replace laboratory blood testing. Clinical decisions based on red blood cell transfusions should be made by the physician after considering at least the following aspects: the patient’s condition, continuous SpHb monitoring and diagnostic laboratory tests on blood samples.

Masimo (NASDAQ: MASI) is a global medical technology company that designs and manufactures a wide range of industry-leading monitoring technologies, including innovative meters, sensors, patient monitors, automation and connectivity solutions. In addition, Masimo Consumer Audio is home to eight legendary audio brands including Bowers & Wilkins, Denon, Marantz and Polk Audio. Our goal is to improve life, increase patient outcomes and reduce the cost of care. Introduced in 1995, Masimo SET ® Measure-through Motion and Low Perfusion™ pulse oximetry has been shown to be superior to other pulse oximetry technologies in over 100 independent and objective studies. 2 Masimo SET ® has been shown to help physicians reduce severe retinopathy of prematurity in newborns, 3 improve CCHD screening in newborns 4 and, with continuous monitoring with Masimo Patient SafetyNet™ in postoperative wards, reduce Rapid Response Team visits, transfers to to reduce the intensive care unit and costs. 5-8 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 in 9 of the top 10 hospitals performing in the 2022-23 U.S. News and World Report Best Hospitals Honor Roll are listed. 10 In 2005, Masimo introduced rainbow ® Pulse CO-Oximetry technology, which enables non-invasive and continuous monitoring of blood components that previously could only be measured invasively, including total hemoglobin (SpHb ® ), oxygen content (SpOC™), Carboxyhemoglobin (SpCO ® ), Methaemoglobin (SpMet ® ), Pleth Variability Index (PVi ® ), RPVi™ (rainbow ® PVi) and Oxygen Reserve Index (ORi™). In 2013, Masimo introduced the Root ® patient monitoring and connectivity platform, designed from the ground up to be as flexible and extensible as possible to facilitate the addition of other Masimo and third-party monitoring technologies. Key additions from Masimo 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 Pulse CO-Oximeters ® includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology such as the Radius-7 ® , Radius PPG ® and Radius VSM ™, handheld devices like the Rad-67 ®, fingertip pulse oximeters like the MightySat ® Rx, and devices that can be used both in the hospital and at home, like the Rad-97 ®. Masimo’s hospital and home automation and connectivity solutions are centered on the Masimo Hospital Automation™ platform and include Iris ® Gateway, iSirona™, Patient SafetyNet, Replica ®, Halo ION ®, UniView ®, UniView :60™ and Masimo SafetyNet ® . The growing portfolio of health and wellness solutions includes Radius Tº ® and the Masimo W1™ watch. For more information about Masimo and its products, visit www.masimo.com.
