Masimo
Encyclopedia
Masimo Corporation is an Irvine, California-based manufacturer of non-invasive patient monitoring technologies. The company is best known for its pulse oximetry
and it sells more pulse oximeters than any other company. Masimo was founded in 1989 by electrical engineer Joe E. Kiani, who was later joined by fellow engineer Mohamed Diab. Masimo invented measure-through motion and low perfusion pulse oximetry, known as Masimo SET (Signal Extraction Technology). Masimo has been recognized for its intellectual property and for being one of the most innovative companies in the medical device industry. The company went public in 2007 and is currently traded on the NASDAQ stock exchange under the symbol MASI. In 2011, Forbes named Masimo to its list of top 20 public companies under a billion dollars in revenue, based on earnings growth, sales growth, and return on equity.
The World Health Organization called Masimo's Pronto-7 non-invasive hemoglobin spot-check device an “innovative medical technology for cost-effectively addressing global health concerns and needs” and the device has been recognized with a gold Medical Design Excellence Award In December 2010, Masimo announced a voluntary recall of the Pronto-7 to address a design issue related to inaccurate readings in certain conditions.

Pulse oximetry
Pulse oximetry is a non-invasive method allowing the monitoring of the oxygenation of a patient's hemoglobin.A sensor is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot....

Masimo SET Pulse Oximetry
Conventional pulse oximetry assumes that arterial blood is the only blood moving (pulsating) in the measurement site. However, during patient motion, the venous blood also moves, which can cause conventional pulse oximetry to under-read arterial oxygen saturation levels because it cannot distinguish between the arterial and venous blood. Masimo SET signal processing identifies the venous blood signal (which has a lower oxygen saturation level than arterial blood), isolates it, and uses adaptive filters to cancel the noise and extract the arterial signal in order to report accurate arterial oxygen saturation and pulse rate. Multiple studies have shown that Masimo SET increases pulse oximetry's ability to detect life threatening events and reduce false alarms. Additional studies have also shown the impact of Masimo SET on patient outcomes, such as helping clinicians detect congenital heart disease in newborns and reduce retinopathy of prematurity in premature infants.Rainbow Pulse CO-Oximetry
Rainbow Pulse CO-Oximetery continuously and non-invasively measures hemoglobin (SpHb), carboxyhemoglobin (SpCO), methemoglobin (SpMet), and pleth variability index (PVI), in addition to oxyhemoglobin (SpO2), perfusion index (PI) and pulse rate. A study at Massachusetts General Hospital showed that SpHb monitoring helped clinicians decrease the frequency of patients receiving blood transfusions during surgery from 4.5% to 0.6%. An emergency department study showed that SpCO increased the detection of carbon monoxide poisoning. Another study showed that PVI monitoring helped clinicians decrease fluid administered during surgery and reduce patient risk.The World Health Organization called Masimo's Pronto-7 non-invasive hemoglobin spot-check device an “innovative medical technology for cost-effectively addressing global health concerns and needs” and the device has been recognized with a gold Medical Design Excellence Award In December 2010, Masimo announced a voluntary recall of the Pronto-7 to address a design issue related to inaccurate readings in certain conditions.
