1 out of 7 HIV+ Patients Receiving Dapsone Therapy at Significant Health Risk Due to Dangerously High Levels of Methemoglobin
IRVINE, Calif., Feb. 6 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry(TM) and Measure-Through Motion and Low-Perfusion pulse oximetry, today announced that a new study presented at the Society for Critical Care Medicine 38th Critical Care Congress suggests providers should consider routine screening with Masimo Rainbow SET Pulse CO-Oximetry for the immediate and noninvasive detection of potentially life-threatening acquired methemoglobinemia in patients receiving Dapsone therapy. Results showed that "Dapsone therapy is associated with a clinically significant elevation of methemoglobin levels" in 1 out of 7 HIV+ patients.
In the study, Hollis R. O'Neal, M.D., and colleagues at the
Masimo Executive Vice President of Medical Affairs, Dr. Michael O'Reilly, stated: "Previous studies have shown that methemoglobinemia can occur in any patient type in any care area of the hospital. This study reinforces the need for clinicians to quickly, easily and conveniently screen all patients receiving Dapsone therapy using Masimo Rainbow SET Pulse CO-Oximetry as the first line of defense and prevention against acquired methemoglobinemia."

Masimo (NASDAQ: MASI) develops innovative 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(R), which virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies demonstrate Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced Masimo Rainbow SET(R) Pulse CO-OximetryTM, a breakthrough noninvasive blood constituent monitoring platform that can measure many blood constituents that previously required invasive procedures. Masimo Rainbow SET continuously and noninvasively measures total hemoglobin (SpHbTM), oxygen content (SpOCTM), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), and PVITM, in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI), allowing early detection and treatment of potentially life-threatening conditions. Founded in 1989, Masimo has the mission of "Improving Patient Outcomes and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications."
