Vasoactive Hormones and Oxygen Saturation During Apneic Events in Patients With Obstructive Sleep Apnea
Not Provided

The mechanisms involved in development and maintenance of hypertension in obstructive sleep apnea are not clarified.

We hypothesize that patients with obstructive sleep apnea have an abnormal level of some vasoactive hormones during apneic events during sleep.
