Masimo Launches Patient SafetyNet and Showcases the Rainbow SET Upgradable Noninvasive Monitoring Platform at 2007 ASA Annu...(SpMet and SpCO in the blood two potentia...)

By continuously, noninvasively and accurately determining levels of SpMet, clinicians can accurately determine if drugs they are administering are causing methemoglobinemia. The drugs that have been shown to contribute to methemoglobinemia include Benzocaine, Cetacaine and Prilocaine, Celecoxib, Dapsone, EMLA Creams, Flutamide, Nitrates, Nitric Oxide, Nitroglycerin, Sodium Nitroprusside, Sodium Nitrate and Sulfonamides.

In a surgical setting, continuous monitoring of SpCO can allow clinicians to detect elevated levels of carboxyhemoglobin that can be caused by everything from desiccated soda lime ("Monday Morning Phenomena") or other poisons during surgery to smokers reporting for surgery with high SpCO values. Increased SpCO compromises healing and may lead to death, and smokers with residual elevated COHb at the time of anesthesia are at cardiac ischemic risk.

Also for the first time at the ASA, Masimo will be showing its latest Rainbow measurement, Pleth Variability Index, or PVI. The ability to noninvasively measure and trend PVI, a continuous noninvasive quantified measurement of changes in the perfusion index that could be indicative of blood volume status, provides additional indicators of a patient's physiologic condition, including the patient's level of hydration. This allows for more precise, timely diagnosis and better treatment decisions that lead to improved patient outcomes.

"At Masimo, we are wholly dedicated and committed to developing products and technologies that enable clinicians to deliver the best possible care and to increase the safety of their patients," Mr. Kiani added. "Since our beginnings nearly 20 years ago, we have been focused on improving patient outcomes and reducing the cost of care by bringing noninvasive monitoring to new sites and new applications.
