For the first quarter of 2009, Masimo reported product revenues of $74.5 million representing a 24.7% increase over $59.7 million for the first quarter of 2008.

Masimo reported that it shipped 27,700 Masimo SET and Masimo Rainbow SET oximetry units, excluding handheld units, during the first quarter of 2009, resulting in at least 587,000 of Masimo SET and Masimo Rainbow SET pulse oximeters in use worldwide. In the first quarter of 2009, revenues from Masimo Rainbow SET products increased to $3.1 million from $2.7 million in the same prior year quarter.

Joe E. Kiani, chairman and chief executive officer of Masimo, said, Despite the continuing difficult economic environment, we are happy that our revenues and earning were better than we had expected in Q1. We believe that this performance is largely due to our gold standard Masimo SET pulse oximetry technology and our expanding Masimo Rainbow SET Pulse CO-Oximetry platform, including the March 23, 2009 commercial release of total hemoglobin, the world’s first continuous non-invasive total hemoglobin monitor.

Masimo also reported that as of April 4, 2009, cash and cash equivalents totaled $152.2 million, up from $146.9 million at January 3, 2009.
