The study will specifically evaluate:
1. Cardiovascular effect of cyclooxygenase inhibitors on cerebral, vascular, blood pressure and homeostatic responses following chronic intermittent hypoxia exposure.
2. Ventilatory response of cyclooxygenase inhibitors following chronic intermittent hypoxia exposure
3. Evaluate the renal hemodynamic effect of chronic intermittent hypoxia exposure and cyclooxygenase inhibition.
