Prevalence of Sleep Disordered Breathing

Stopped early

Conditions studied: Unstable Angina, Acute Myocardial Infarction, Congestive Heart Failure

In brief

A novel technique in identifying unspecified sleep apnea has been developed. This technique uses signals typical acquired from a bedside monitor that is found in critical care environments. Those signals are then processed by a sleep analysis algorithm to provide an Apnoea Hypopnea Index (AHI) score. This study is intended to determine whether the prevalence of sleep disordered breathing identification among patients in a Coronary Care Unit (CCU) using this novel approach is significantly different than using routine techniques.
