Brazil’s A.C.Camargo Cancer Center Adopts Masimo SpHb for Noninvasive and Continuous Hemoglobin Monitoring

 Masimo (NASDAQ: MASI) announced today that A.C.Camargo Cancer Center in Sao Paulo, Brazil has installed Masimo’s noninvasive and continuous hemoglobin (SpHb®) technology to monitor surgical patients.

Clinicians use invasive blood sampling and laboratory analysis of hemoglobin to determine hemoglobin levels and help estimate blood loss to determine need for red blood cell transfusions. However, lab-based hemoglobin is only available intermittently and results are often delayed. SpHb offers real-time visibility to changes – or lack of changes – in hemoglobin between invasive blood sampling.

“The data associating transfusion with higher mortality rates was clear, so we knew we had to implement strategies to reduce transfusions,” said Dr. Eduardo Henrique Joaquim Giroud, anesthesiologist and Director of the Department of Anesthesiology at A.C.Camargo Cancer Center. “This technology enables us to noninvasively and continuously monitor hemoglobin, a strong indicator of blood loss. It provides continuous trend data which, in combination with invasive blood sampling data, helps us determine who actually needs to be transfused and the right amount of blood needed, not more, and not less.”

SpHb monitoring may provide additional insight between invasive blood sampling when:

The SpHb trend is stable and the clinician may otherwise think hemoglobin is decreasing

The SpHb trend is rising and the clinician may otherwise think hemoglobin is not increasing fast enough

The SpHb trend is dropping and the clinician may otherwise think hemoglobin is stable

“For over 60 years, the A.C.Camargo Cancer Center has been serving as an international reference center for prevention, multidisciplinary treatment, teaching and research of cancer,” stated Joe Kiani, Founder and CEO of Masimo. “We are happy to see them adopt SpHb technology through Masimo’s Root® patient monitoring and connectivity platform for the betterment of their patients.”

About Masimo

Masimo (NASDAQ: MASI) is the global leader in innovative noninvasive monitoring technologies that significantly improve patient care – helping solve "unsolvable" problems. In 1995, the company debuted Measure-Through Motion and Low Perfusion pulse oximetry, known as Masimo SET®, which virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies have shown that Masimo SET® outperforms other pulse oximetry technologies, even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. 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®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI). In the U.S., Masimo rainbow® SET pulse cooximeter instruments and sensors are indicated to provide noninvasive monitoring of arterial oxygen saturation (SpO2) and pulse rate (PR), carboxyhaemoglobin saturation (SpCO®), methaemoglobin saturation (SpMet®), total hemoglobin concentration (g/dl SpHb), and/or respiration rate (RRa®). The devices are not intended to replace laboratory measurements of hemoglobin and have not been cleared by FDA to detect bleeding or reduce the amount or frequency of red blood cell (RBC) transfusions.
