Masimo Oximeters and Neonatal Sensors Receive FDA 510(k) Clearance with Labeling for Use in Newborn Screening for Critical Congenital Heart Disease (CCHD)

Masimo Announces HEART Program for CCHD Screening to Provide a Free Masimo SET® Pulse Oximeter to Hospitals in Need

IRVINE, Calif., Sept. 24, 2012 /PRNewswire/ -- Masimo (NASDAQ: MASI) announced today that it has received U.S. FDA 510(k) clearance for Masimo Signal Extraction Technology® (SET®) pulse oximeters, rainbow® SET® Pulse CO-Oximeters®, and neonatal sensors with labeling for screening newborns for critical congenital heart disease (CCHD).  Masimo SET® pulse oximeters and sensors have previously been cleared to measure oxygen saturation and pulse rate during motion and low perfusion conditions in newborns, but this marks the first time the FDA has cleared specific labeling indicating the use of pulse oximeters, in conjunction with a physical exam, to screen newborns for CCHD.

In conjunction with the FDA clearance, Masimo also announced the HEART Program (Help Ensure Access to the Right Technology) for CCHD screening enabling hospitals in countries where Masimo has a presence that want to perform CCHD screening with a Masimo SET® pulse oximeter, but do not have one and do not have funds to purchase one, to receive a free Masimo SET® pulse oximeter. More details are available at

CCHD causes up to 3% of all infant deaths in the first year of life.1  According to the U.S. Department of Health and Human Services (HHS), these types of heart defects affect about 7 to 9 of every 1,000 live births, one quarter of which could be detected and potentially treated by measuring blood oxygen saturation.  FDA clearance comes as California recently became the latest state to mandate CCHD pulse oximetry screening (, following HHS's September 2011 action to add pulse oximetry CCHD screening for newborns as part of the Recommended Uniform Screening Panel.

HHS took this action based on the published findings of the CCHD Workgroup,2 which relied on two major independent, published, prospective clinical studies that exclusively used Masimo SET® Measure-Through Motion and Low Perfusion pulse oximeters to recommend screening with "motion-tolerant pulse oximeters" that "have been validated in low perfusion conditions."  Both of the studies were submitted by Masimo to the FDA to support the new CCHD screening labeling.

  • Dr. Anne de-Wahl Granelli, et al., reported on the results of screening 39,821 newborn subjects at five maternity centers in Sweden. Investigators used the Masimo Radical™ with Masimo SET® technology, and found pulse oximetry screening of all well babies in maternity units is practically feasible with a minimum use of nursing time, and that it significantly improves detection of duct dependent heart disease before hospital discharge. The low false positive rate, the fact that other important pathology is unearthed by the screening, and the likely reduced need for preoperative neonatal intensive care suggest that such screening will be cost effective.3
  • Dr. Andrew Ewer, et al.,studied 20,055 newborn subjects at six maternity centers in the UK. Investigators used the Radical-7® with Masimo rainbow® SET® technology and found pulse oximetry to be a safe, feasible test that adds value to existing screening. It identifies cases of critical congenital heart defects that go undetected with antenatal ultrasonography, and the early detection of other diseases is an additional advantage.4

In spite of the wide availability of Masimo SET® pulse oximetry, both as standalone products as well as integrated products in over 100 multiparameter monitors from over 50 brands, some hospitals still do not have Masimo SET® technology.  Given the strong evidence supporting the use of Masimo SET pulse oximetry for CCHD screening and Masimo's commitment to help save and improve babies' lives through expanded CCHD screening programs, the company's HEART Program (Help Ensure Access to the Right Technology) for CCHD screening will help ensure that hospitals have access to Masimo SET technology for CCHD screening.

"We are very proud of where we have taken pulse oximetry," stated Masimo founder and CEO, Joe Kiani.  "Before SET pulse oximetry, CCHD screening was impractical, if not impossible with pulse oximetry.  Dr. Graneli's initial study showed that even a so called 'next generation' pulse oximeter wasn't able to reliably work for CCHD screening, and was abandoned in the middle of the trial, while Masimo SET delivered the groundbreaking results of high sensitivity and specificity that became the basis for this new standard of care.  We are truly elated with this new FDA clearance.  We feel that with it, comes the responsibility to make CCHD pulse oximetry screening more accessible for infants, the most defenseless patients in any healthcare setting.  We are excited to announce that, in conjunction with this new FDA clearance, we are launching the HEART Program for CCHD screening—offering a free Masimo SET® pulse oximeter to hospitals that need one but can't afford it.  In this way, we are helping to address unmet needs on behalf of newborns around the world."

The Masimo pulse oximeters that were the subject of this 510(k) clearance are the Radical-7®, Rad-57™ and Rad-87™ Pulse CO-Oximeters with Masimo rainbow SET, and the Rad-5®, Rad-5v™ and Rad-8® Pulse Oximeters with Masimo SET.

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 SET® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, 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 2008, Masimo introduced Patient SafetyNet™, a remote monitoring and wireless clinician notification system designed to help hospitals avoid preventable deaths and injuries associated with failure to rescue events. In 2009, Masimo introduced rainbow® Acoustic Monitoring, the first-ever noninvasive and continuous monitoring of acoustic respiration rate (RRa™). Masimo's rainbow® SET® technology platform offers a breakthrough in patient safety by helping clinicians detect life-threatening conditions and helping guide treatment options. In 2010, Masimo acquired SEDLine®, a pioneer in the development of innovative brain function monitoring technology and devices. In 2012, Masimo acquired assets of Spire Semiconductor, LLC, maker of advanced light emitting diode (LED) and other advanced component-level technologies; and acquired PHASEIN AB, a developer and manufacturer of ultra-compact mainstream and sidestream capnography, multigas analyzers, and handheld capnometry solutions. Masimo SET® and Masimo rainbow® SET® technologies also can be found in over 100 multiparameter patient monitors from over 50 medical device manufacturers around the world. Founded in 1989, Masimo has the mission of "Improving Patient Outcome and Reducing Cost of Care ... by Taking Noninvasive Monitoring to New Sites and Applications®."
