IRVINE, Calif., Dec. 13, 2010 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI) announced today that a new clinical study demonstrating the accuracy of its latest medical technology breakthrough—Rainbow Acoustic Monitoring™—was presented last week at the American Association of Respiratory Care's (AARC) 56th Annual International Respiratory Congress in Las Vegas. The largest gathering of respiratory care clinicians in the world, the AARC Annual Meeting provides an important platform for previewing the latest in medical developments and clinical research to respiratory care thought-leaders.

The study presented by Jim Kumpula, RRT, System-wide Manager of Respiratory Care Services at Swedish Medical Center, evaluated the accuracy of acoustic respiration rate (RRa) measurements, obtained noninvasively with Masimo's Rainbow Acoustic Sensor and continuously displayed on the Radical-7 Pulse CO-Oximeter, in 25 patients on an acute nursing unit in comparison to manual estimates of respiration rate obtained via clinical auscultation (listening to breathing sounds with a stethoscope) and visual observations of patient breathing. After analyzing 187 respiratory rate data pairs collected (7.4 +/- 4.6 data pairs per patient) with bias and precision of 0.8 and 3.4 bpm respectively, Kumpula concluded that Rainbow Acoustic Monitoring was a "simple and automatic method of measuring respiration rate at the bedside, with clinically acceptable accuracy" that could be of "significant value in a wide range of clinical settings including the general care floor, PACU, OR, sleep laboratories, and any care area utilizing conscious sedation."(1)
