Seems fairly bizarre.
Take a group of patients whose brains are struggling to work and mess about with their blood gases in ways that tend to make it difficult for brains to work.

Primary Purpose: Treatment
Allocation: Randomized
Interventional Model: Crossover Assignment
Masking: None (Open Label)

Participant Group/Arm
Experimental: Acute exposure: Placebo, Progressive Carbon Dioxide, Intermittent Hypoxia

Study group will receive the three interventions in this order: Placebo, Progressive Carbon Dioxide, then Intermittent Hypoxia

Intervention/Treatment
Other: Acute Placebo Visit

• The placebo visit will include 6 simulated cycles of 5 minutes breathing 21% oxygen from a douglas bag and 5 minutes breathing room air.

Other: Acute Progressive Carbon Dioxide

• The progressive carbon dioxide visit will include a 60-minute progressive ramp which includes 6 cycles of progressive CO2 ramping starting at 0% and progressing up to 10% within 5 minutes immediately followed with 5 minutes of room air breathing in between cycles.

Other: Acute Intermittent Hypoxia

• The intermittent hypoxia exposure visit will include 6 cycles breathing 8-12% oxygen (O2) for 5 minutes with a target pulse oximeter saturation of 86-90%, followed by 5 minutes of breathing room air.
