Masimo's PI measurement

IRVINE, Calif., Nov. 14 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry and Read-Through Motion and Low Perfusion pulse oximetry, reported that a new independent and objective clinical study demonstrates the ability of Masimo SET Perfusion Index (PI) to improve detection of congenital heart defects (CHD) in newborns with duct-dependent systemic circulation. Even when routine neonatal physical examinations and saturation screenings fail, PI may help to accurately detect CHD-enabling life-saving early detection and critical intervention before discharge from the hospital. It has been documented that up to 30% of all deaths from CHD in the first year of life are due to unrecognized cases being discharged to the home.

PI is a measurement featured in the Masimo Rainbow SET technology platform that reflects the real-time changes in peripheral blood flow at the monitored site and the strength of the plethysmographic signal displayed on the pulse oximeter. In addition to improving the detection of CHD in infants, the ability to noninvasively and continuously measure PI could enable faster identification of clinically significant changes in a patient's physiologic status, including potentially hypothermia, hypovolemia, shock and/or sepsis.

In the study, entitled "Noninvasive Peripheral Perfusion Index as a Possible Tool for Screening for Critical Left Heart Obstruction," conducted at the Institute of Clinical Sciences, Gothenburg University, Sweden, A de-Wahl Granelli and I Ostman-Smith observed whether PI was a dependable indicator in critically-ill newborns to enable its use for congenital heart disease screening purposes. The researchers indicated that several studies have reported that babies with congenital heart disease are not detected by routine neonatal physical examinations and that neon
