A Case of De Novo Positional Complex Sleep Apnea Syndrome (CompSAS)

Obstructive sleep apnea (OSA) is well known to often improve with non-supine positioning as opposed supine positioning. Emerging research supports a role for position management in patients central (CSA) well. We report case of de novo complex syndrome (CompSAS) 78-year-old female, who presented after car accident due unclear syncope. Diagnostic polysomnography (PSG) showed moderate OSA. A CompSAS developed under automatic positive airway pressure (APAP), while 4 years downloaded data good adherence. No significant benefit was reported adaptive servo ventilation (ASV) and BiPAP-ST, reduction CSA the noticed. Oxygen positional therapy (SPT) were considered, resulting improvement quality. Further on prevalence needed.
