GoKawiilPNOĒ launches self-administered metabolic testing mask on October 1
PNOĒ, a Malden, Massachusetts-based company with operations in Athens, Greece, is releasing the PNOĒ 2.0, a mask-based device that measures oxygen consumption and carbon dioxide output without requiring a trained operator. CEO Apostolos Atsalakis said users can simply wear the mask, press a button, and breathe for eight minutes to get results. The device builds on metabolic testing technology long used to measure VO₂ max in sports labs and hospitals.
