Condition sleep apnea syndrome
Treatment chronic intermittent hypoxia
Sponsor University Hospital, Grenoble
Start date September 2005
End date July 2007
Trial size 12 participants
Trial identifier NCT00746928, 05-CHUG-23


The study is a prospective field evaluation to assess the effects of the chronic Intermittent Hypoxia exposure in 12 healthy humans.

Precisely, the study was designed to :

Set up a new model of Chronic Intermittent Hypoxia (CIH) applied to healthy human. This CIH is mimicking the CIH undergone by patients suffering from Sleep Apnea Syndrome.

Evaluate the cardiovascular effect of CIH. Neuronal and humoral sympathetic control, blood pressure control, vascular resistance.

Evaluate the Sleep quality, the ventilation under exposure and the long terms effect on ventilation control of CIH (central and peripheral chemoreflex).

Investigates the biological aspects of CIH exposure.
