Role of Cerebral Blood Flow on Ventilatory Stability During Sleep in Normoxia and Intermittent Hypoxia

A prospective double blind, placebo-controlled, randomized cross-over trial to evaluate the effect of lowering cerebral blood flow on the ventilatory chemoreflexes (acute hypoxic and hypercapnic ventilatory responses).

Inclusion: Healthy adults; 18 - 45 years of age; Living in Calgary for the past one year; Have no medical condition or should not be taking any blood pressure medications; The participant should not be lactose intolerant.

Exclusion: Cerebrovascular, cardio-respiratory, renal and metabolic diseases; Bleeding disorders and upper gastrointestinal diseases e.g. peptic ulcer disease; Drug allergies to non-steroidal anti-inflammatories; Pregnancy, obese and sleep-disordered breathing; Currently smoking.
