Improvements of central respiratory events, Cheyne-Stokes respiration and oxygenation in patients hospitalized for acute decompensated heart failure

Sleep-disordered breathing (SDB), and Cheyne-Stokes respiration (CSR) in particular, are associated with reduced survival in patients with acute decompensated heart failure (ADHF). CSR cycle length (CL) has been shown to mirror heart failure severity and therefore may be a predictor of outcome. However, studies characterizing CSR in ADHF are rare and no study has investigated changes in CSR from admission to discharge in ADHF patients.
