masimo corp (MASI) Details

Masimo Corporation, a medical technology company, develops, manufactures, and markets noninvasive monitoring technologies worldwide. It offers Masimo Signal Extraction Technology (SET) with measure-through-motion and low-perfusion pulse oximetry monitoring to address the primary limitations of conventional pulse oximetry. The company also provides Masimo rainbow SET Platform, which includes rainbow SET Pulse CO-Oximetry products that noninvasively monitor multiple blood-based measurements, including oxygen saturation, pulse rate, perfusion index, pleth variability index, and respiration rate from pleth; noninvasively monitor hemoglobin, carboxyhemoglobin, and methemoglobin; monitor arterial oxygen saturation; and calculates oxygen content and oxygen reserve index. In addition, it offers SedLine brain function monitoring technology that measures the brain’s electrical activity by detecting EEG signals; capnography and gas monitoring products, such as external plug-in-and-measure capnography and gas analyzers, integrated modules, and handheld capnograph and capnometer devices; O3 regional oximetry for tissue oxygen saturation measurement; SafetyNet, a patient surveillance, remote monitoring, and clinician notification solution; and Halo Index, an indicator that facilitates trending and assessment of physiological measurements. Further, the company offers remote alarm/monitoring solutions, software, and connectivity solutions. The company’s patient monitoring technologies incorporate a monitor or circuit board and sensors, including proprietary single-patient use, reusable and rainbow ReSposable sensors, and patient cables. Masimo Corporation provides its products directly, as well as through distributors and original equipment manufacturers partners to hospitals, emergency medical service providers, physician offices, veterinarians, long term care facilities, and consumers. The company was founded in 1989 and is headquartered in Irvine, California.

masimo corp (MASI) Key Developments

Penn Highlands Selects SedLine Brain Function Monitoring from Masimo Corporation

Penn Highlands DuBois has selected SedLine brain function monitoring through the Root patient monitoring and display platform from Masimo Corporation to monitor patients under anesthesia or sedation. Penn Highlands DuBois had been using Bispectral Index (BISTM) technology from Covidien. Root offers Masimo's SedLine brain function monitoring, which provides four channels of EEG to help clinicians better understand the effects of anesthesia on the brain. SedLine measures the effects of anesthesia and sedation by monitoring both sides of the brain's electrical activity. As such, SedLine provides a wealth of EEG-based data, which can help clinicians monitor anesthesia.

Masimo Announces New Clinical Study on Oxygen Reserve Index(TM) or ORI(TM)

Masimo announced that a new clinical study presented at the International Anesthesia Research Society's 2015 Annual Meeting showed that Masimo's latest noninvasive patient monitoring parameter, Oxygen Reserve Index(TM) or ORI(TM), could help clinicians in the early detection of an impending desaturation in patients receiving supplemental oxygen. Pulse oximetry (SpO2) provides noninvasive and continuous visibility to arterial blood oxygenation in hypoxia and normoxia (normal oxygenation). Clinicians often use arterial oxygen partial pressure (PaO2), which can be intermittent and delayed, to monitor levels of hyperoxia (higher than normal oxygenation). Between invasive sampling, changes in PaO2 can be difficult to assess, and therefore hypoxia or hyperoxia can occur unexpectedly. ORI, Masimo's 11th rainbow(r) parameter2, is a relative index of the partial pressure of oxygen in arterial blood (PaO2) in the range of 100 to 200 mmHg. ORI is intended to supplement, not replace, SpO2 monitoring and PaO2 measurements.

Korean Regulators Clear Masimo PVI(R) for Clinical Use

Masimo announced that the Republic of Korea'sMinistry of Food and Drug Safety (MFDS) and the Korean Health Technology Assessment (HTA) group have cleared Masimo's noninvasive PVI® -- a measure of the dynamic changes in the perfusion index that occur during one or more complete respiratory cycles -- for clinical use. Korean regulators determined that PVI is an effective, noninvasive way to predict fluid responsiveness in mechanically ventilated patients. Regulators concluded PVI has higher accuracy of diagnosis compared to static indices (central venous pressure, pulmonary capillary wedge pressure), and similar accuracy diagnosis with dynamic indices (cardiac output variability, pulse pressure variability, blood volume amplitude variability, systolic pressure variability). They stated: Pleth Variability index (PVI) measurement measures pleth variability non-invasively with the sensor on the skin of patients, so that there is no issue for safety. Clinicians commonly use fluid administration to improve haemodynamics before, during and after surgery. Assessment of fluid responsiveness -- the ability of the circulation system to increase cardiac output in response to volume expansion -- is essential to guide fluid therapy and optimize preload.(1) Too little fluid administration can result in low perfusion in peripheral tissue, but too much fluid administration can result in patients failing to respond to any amount of volume expansion,(2,3) as well as fluid overload postoperatively. This clearance by Korean regulators is similar to the decision of the French Society for Anaesthesia and Intensive Care [2] (SFAR), which in 2013 added PVI to guidelines for optimal haemodynamic management during surgery.(6) Similar to Korean authorities, SFAR recommends the use of "dynamic" parameters such as PVI that measure variations over the respiratory cycle.
