Summary

This study will look at the safety, tolerability and feasibility of a non-invasive treatment called Acute Intermittent Hypoxia (AIH) in people with Multiple Sclerosis (MS) at different stages of the disease course.

Acute Intermittent Hypoxia

Hypoxia (10% O2) will be administered via a non-rebreather face mask connected to an oxygen tank supplying the 10% O2. Each session will involve 15 cycles of hypoxia, each lasting 90 seconds, interspersed with 60 second cycles of normoxia. The total duration of each session will be approximately 37 minutes. An inline oxygen analyzer will allow recording of the percentage of oxygen being delivered. A fingertip pulse-oximeter will be worn throughout to ensure that oxygen saturation (SpO2) falls to a nadir between 80 - 87% during hypoxic episodes and heart rate monitoring will be performed. Blood pressure will be checked prior to and following each session (within 5 minutes of treatment cessation).
