This is a study to validate the efficacy of using a small portable oxygen source to mitigate altitude-induced hypoxia.

The purpose of this study is to validate the efficacy of using a small portable oxygen source to mitigate altitude-induced hypoxic events. To do so, the invesitgators propose the following aims:

1. Determine the ability of a portable oxygen storage device to reverse hypobaric hypoxemia in volunteers at altitude.
2. Determine the duration of time that a single portable oxygen container can maintain normoxia in normal volunteers at altitude.
3. Determine the optimum dose and timing of oxygen use to reverse hypobaric hypoxemia.

Inclusion Criteria:

• Altitude chamber qualified
• Previous agreement to be approached regarding altitude chamber research

Exclusion Criteria:

-

Normal volunteers aged 18 to 65 years, inclusive
