* Have severe peripheral vascular disease.
* Have a documented diagnosis of sleep apnea.

Primary outcomes:
measure: The primary efficacy measurement of this study is the mean change after 8 weeks of treatment from baseline in cuff seated trough diastolic blood pressure, cuff seated systolic blood pressures and automated blood pressure monitoring
Secondary outcomes:
measure: Safety will be assessed by evaluating all reported adverse events and changes in clinical laboratory values, ECGs, and vital signs
