SportsMask designed by breathing expert Patrick McKeown. Used with Oxygen Advantage technique to perform high altitude training.
When altitude is simulated, pulse oximetry will show your blood oxygen saturation (SpO2%) lowering to below 91%. By wearing SportsMask while applying the OxygenAdvantage technique, you can observe your blood oxygen saturation lower to 80 to 87%, simulating training at an altitude of 4,000-5,000 meters (13,000- 16,400 ft).
