Project Description Narrative:


Obstructive sleep apnea (OSA) is a major public health problem with a high prevalence in Wisconsin, affecting 9% of women and 24% of men. Patients with OSA have many negative health consequences, including hypertension, cardiovascular disease, and cerebrovascular disease due to fragmented sleep and reductions in blood oxygen saturation. Because treatment for OSA is often either ineffective or high-cost and invasive, many patients never find adequate relief. There is a need to develop low-cost, non-invasive methods to identify the site of airway collapse in order to assist clinicians in selecting the optimal treatment for each patient to improve individual and population health outcomes.

Through this award, investigators aim to develop methods to detect the most common contributor to obstructive sleep apnea in order to provide new knowledge and data to inform better diagnosis and treatment options for patients.
