A Single Center Study to Demonstrate the Safety and Performance of Lifelight® First Software Application

"Participants enter a chamber with a modifiable atmosphere and sit on a bench associated with an exercise bicycle. The subject breathes hypoxic air to achieve various SpO2 readings throughout the range of 80-97%.~The participants undertake recumbent cycling for up to 10 minutes at various intervals and differing oxygen/nitrogen balances to induce changes in their vital signs.~Measurements of the Vital Signs are taken at various time points using Lifelight First and the reference device using 2 observers"
