Study Summary
This study will evaluate the effect of hypoglossal nerve stimulation (HGNS) on different measures of cardiovascular function in patients with obstructive sleep apnea (OSA). People with OSA who have undergone implantation of the hypoglossal nerve stimulator at the study site will be told about the study at their 2-week post-operative appointment. Those who decide to participate will have blood drawn and vascular function measurements taken before HGNS activation, during treatment, and after a temporary treatment withdrawal period. Following the 30-day period of treatment withdrawal, the HGNS therapy will be reactivated.
Primary Outcome
Peripheral arterial tonometry (PAT) is a method for measuring endothelial dysfunction in a non-invasive way. Blood flow is measured in the fingertips following compression with an inflatable cuff on the upper arm. Participants will lay on their backs with a probe placed on the finger of each hand. The probes are attached to a computer that records finger blood flow. The finger probes will continuously record the blood flow in the fingertips for 10 minutes
