No results posted yet for this study

Summary

The purpose of this study is to study the effects of carbon dioxide combined with head down tilt on cerebral physiology and anatomy. This paradigm will help establish a ground-based analog for spaceflight, and also evaluate the ability of non-invasive devices to monitor brain physiology.

Conditions

  • Healthy

Interventions

OTHER

0.5% CO2

The subjects will be randomized to breath 0.5% carbon dioxide during one of the -12 degree head down tilt body position periods in crossover design

OTHER

ambient air

The subjects will be randomized to breath ambient air during one of the -12 degree head down tilt body position periods in crossover design
