Improving Human Cerebrovascular Function Using Acute Intermittent Hypoxia
NCT05164705 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 33
Last updated 2024-07-09
Summary
This study uses magnetic resonance imaging to determine whether 3 weeks of repeated exposure to Acute Intermittent Hypoxia can improve brain blood flow or blood flow regulation in healthy adults.
Conditions
- Healthy Brain Perfusion
Interventions
- OTHER
-
Acute Intermittent Hypoxia
Participants will wear a non-rebreathing face mask and alternate between breathing 9% O2 gas mixture for up to 1 minute, or until the target SpO2 of 85 percent is reached, and normal room air (21 percent O2) until 2 minutes are complete. This cycle will be repeated 15 times, resulting in a 30-minute protocol.
