For the first time in freediving history, Masimo MASI, -2.04% maker of breakthrough Measure-through Motion and Low Perfusion(TM) pulse oximetry, has equipped the Suunto Vertical Blue freediving competition with consumer versions of MightySat(R) fingertip pulse oximeters.
“Vertical Blue is looking forward to collaborating this year with Masimo, as part of our efforts to be more informed as to the fascinating physiological changes that occur during deep breath-hold dives,” said William Trubridge, 15-time world record holder and founder of Vertical Blue. “Using Masimo equipment, we can collect more data and monitor our athletes throughout the event, with very simple and noninvasive protocols. We’re looking forward to seeing the results!“
Before dives, freedivers typically prepare with physical, mental and breath-holding exercises to slow their metabolism, heart rate, breath rate, and the level of carbon dioxide in their bloodstream. Despite these precautions, athletes who are pushing their limits in well supervised competitions are still at risk of experiencing shallow- and deep-water blackouts. At #VB2015, all of the competitors will be under the watchful eyes of a world-class safety team, sponsored by Masimo and led by Stephen Keenan of Dahab Feedivers. Additionally, the holder of the Guinness Book of World Records for an underwater breath hold (22 minutes), Dr. Stig Severinsen, will monitor blood oxygenation, pulse rate and other parameters throughout the 10-dayevent using a MightySat. Severinsen’s monitoring will advance the understanding of one of the world’s fastest-growing niche sports.
“The monitoring of these world class athletes with this new state-of-the-art device should hopefully yield reliable data to be used to inform improved training and competition protocols – also in sports other than freediving,” Severinsen said. “I am excited to be testing the MightySat at Vertical Blue and honored to be given the chance to collect unique scientific data, which will not only be part of the first true “Preventive Protocol” in extreme freeediving but hopefully also extend into the world of medical care and patient safety in the future.”
MightySat is available in three versions — each 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.
