Guest Blogger: Mattias Baumert Overview What is the problem being addressed? Our objective was to quantify the burden of cortical arousals throughout sleep and determine its association with long-term cardiovascular (CV) and overall mortality. What was the approach to solving the problem? We quantified arousal burden (AB) as the cumulative duration of all arousal events relative to total sleep time in three large cohort studies.

A patient's apnea-hypopnea index (AHI) determines whether or not they are eligible for reimbursable treatment. But how certain can we be that a patient's AHI is actually above or below a clinical threshold? In this study using 2049 subjects from MESA dataset from NSRR, we develop a metric for computing a confidence interval around a patient's AHI. Keep reading
