Study Published in British Medical Journal Indicates Masimo SET May Also
Reduce the Need for Pre-Operative Neonatal Intensive Care and Prevent
Long-term Neurological Morbidity
IRVINE, Calif., Jan. 30 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI),
the inventor of Pulse CO-Oximetry and Measure-Through Motion and Low Perfusion
pulse oximetry, today announced that a new multi-center study of 39,821
newborns was published in the January 2009 issue of the British Medical
Journal (BMJ). When compared to a cohort group of 108,604 newborns in whom no
pulse oximetry screening was used, the study found that the addition of Masimo
SET pulse oximetry screening before discharge increased detection of
Congenital Heart Disease (CHD) by 28% (from 72% to 92%). In addition,
researchers noted that "no baby died from undiagnosed duct dependent
circulation" in the Masimo SET group, while five babies from the cohort group
died during the same period.(1)
In the study, Anne de-Wahl Granelli, M.D., of the Queen Silvia Children's
Hospital in Goteborg, Sweden, and colleagues screened babies born between 2004
and 2007 at five well baby nurseries using Masimo SET pulse oximetry. A
positive pulse oximetry result was defined as an oxygen saturation of <95%
measured both preductally (right hand) and postductally (either foot), or a
measurement difference >3% between the two measurements. The study found that
the positive predictive value of pulse oximetry screening was at least seven
times higher than the best-case scenario for standard neonatal physical
examination alone (20.7% vs. 3.1%).
Undiagnosed CHD presents devastating long-term morbidity and mortality
risks, with 10-30 percent of the babies who die from CHD remaining undiagnosed
until autopsy.(2) Additionally, study authors noted that the rise in the
proportion of babies who leave the hospital with undiagnosed critical CHD had
multiple contributing factors, such as earlier discharge from maternity wards,
the growing prevalence of babies rooming with their mothers instead of
observational nurseries and reductions in pre-discharge neonatal clinical
exams.
The researchers concluded that Masimo 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
CHD. Researchers also commented that "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."
The current study adds to previous research conducted by Dr. Granelli,
which demonstrated that when compared to conventional pulse oximetry, only
Masimo SET pulse oximetry is accurate and reliable for improving the detection
of critical CHD.(3)
Masimo Executive Vice President of Medical Affairs Dr. Michael O'Reilly,
stated: "Undiagnosed CHD frequently places the lives of newborns in grave
danger. To ensure that these newborns are given the absolute best chance at
survival, pre-discharge CHD detection and diagnosis is critical. The
comprehensive population and protocol data gathered by these researchers
demonstrate that the superior sensitivity and specificity of Masimo SET pulse
oximetry technology is key to substantially increasing the ability to
accurately diagnose CHD before newborns are discharged from the hospital."

About Masimo
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-Oximetry(TM), 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
(SpHb(TM)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO(R)),
methemoglobin (SpMet(R)), and PVI(TM), 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." Additional
