Masimo Unveils MightySat at Consumer Electronics Show

Visit Booth 73711 at CES in Las Vegas to Witness Death-Defying and Olympic-Level Demonstrations Showing How MightySat Delivers Accurate Measurements When Other Pulse Oximeters Fail

Masimo (NASDAQ:MASI) today announced the MightySat fingertip pulse oximeter for personal use. MightySat provides accurate oxygen saturation and pulse rate measurements when other pulse oximeters can fail Reference 1 and is ideal for those who want reliable measurements even under extreme conditions.

MightySatTM fingertip pulse oximeter provides oxygen saturation(SpO2), pulse rate (PR), perfusion index (PI), and pleth variability index (PVi®). Oxygen saturation (the percentage of arterial blood that is bound with oxygen) and pulse rate (the number of times the heart beats per minute) provide an indication of lung and heart efficiency and increasingly are being measured with fingertip pulse oximeters for personal use. However, until now no fingertip pulse oximeter has been available with Masimo SET® Measure-through Motion and Low PerfusionTM pulse oximetry – the same technology used on more than 100 million patients a year in leading hospitals worldwide. Now, instead of guessing whether their pulse oximeter is providing accurate measurements, people can rely on MightySat with Masimo SET® technology – shown in more than 100 independent and objective studies to outperform all other pulse oximetry technologies with dramatically fewer false measurements during motion and low perfusion (or low blood flow) to the finger.Reference1

MightySat is available in three versions – each of which provides oxygen saturation (SpO2), pulse rate (PR), and perfusion index (PI) measurements in a compact, battery-powered design with a large color screen that can be rotated for real-time display of the pleth waveform as well as measurements. Optional Bluetooth wireless functionality enables measurement display via a free, downloadable app on iOS and Android mobile devices as well as the ability to trend and communicate measurements. And for those who want to use their pulse oximeter to evaluate another physiologic dimension, MightySat is the only fingertip pulse oximeter available with the optional Pleth Variability Index (PVi®), a measure of the dynamic changes in the PI that occur during one or more complete respiratory cycles.Reference2

Other standard features include:

  • I.Q.® to assess measurement confidence
  • lightweight design for operation in challenging environments
  • battery life–up to 15 hours with two standard AAA alkaline batteries
  • year limited warranty

Elite athletes are among those who trust Masimo SET® pulse oximetry to help them achieve peak performance. Stig Severinsen, Ph.D. in medicine, a four-time World Champion freediver and owner of multiple Guinness World Records, including history’s longest breath-hold of 22 minutes, will demonstrate MightySat while holding his breath in a coffin-sized water tank during the CES trade show in Las Vegas, Jan. 6-9, Booth 73711, Tech West, Sands Expo.

Also at the Masimo booth will be Dotsie Bausch, a seven-time USA Cycling National Champion, two-time Pan-American Champion, and silver medalist in team pursuit cycling at the 2012 London Olympics, who will perform her Olympic-level training, demonstrating Masimo SET® technology measurements.

“Training for extreme records under extreme conditions is always a huge challenge,” said Severinsen, who was the subject of a recent National Geographic television special, when he used Masimo technology prior to freediving inside an iceberg. “In such situations it is of great value to be able to perform noninvasive and accurate measurements of my heart rate and oxygen saturation levels with a state-of-the-art device.

“I would recommend Masimo’s MightySat to anyone interested in health and fitness – understanding what goes on inside your body is paramount to improving performance,” he added.

About Masimo

Masimo is a publicly traded company (NASDAQ: MASI) based in Irvine, California. Masimo is the leading brand of hospital pulse oximeters Reference 1 because they provide accurate measurements when other pulse oximeters fail by using a revolutionary, patented invention called Signal Extraction Technology® open paren (SET®)close paren. Masimo SET® uses five parallel signal processing engines that measure through challenging conditions, including movement and low blood flow. With MightySat, the same high-performing Masimo SET® technology is now available for general wellness and health applications.
