Summary

The sleep apnea-hypopnea syndrome (SAHS) is a respiratory disorder characterized by frequent breathing cessations (apneas) or partial collapses (hypopneas) during sleep. SAHS is linked with the most important causes of death in adults from industrialized countries. Metabolic deregulation and cardiovascular and cerebrovascular diseases, such as atrial fibrillation, stroke, myocardial infarction and sudden cardiac death, could affect people having untreated SAHS. The gold standard method for SAHS diagnosis is in-hospital, technician-attended nocturnal polysomnography (PSG). Nevertheless, this methodology is labor-intensive, time-consuming, and relatively unavailable, especially in low-resource settings. These drawbacks have led to large waiting lists, which delay diagnosis and treatment and limits its effectiveness as single diagnostic method for SAHS. Blood oxygen saturation (SpO2) and pulse rate (PR) from nocturnal pulse oximetry (NPO) provide relevant and essential information to detect apneas. In addition, it is significantly less intrusive for patients and it can be easily recorded at patients' home. In the same way, automated signal processing and pattern recognition techniques have demonstrated to provide accurate tools able to detect and effectively use this information. Therefore, the investigators hypothesize that automated pattern recognition of at-home NPO recordings could provide reliable and efficient tools able to simplify the management of SAHS. The aim of this study is two-fold: 1) to prospectively assess the reliability and effectiveness of at-home NPO in the context of adult SAHS; 2) to design, optimize and extensively assess the diagnostic performance of automated NPO-based screening tools for SAHS. In order to achieve these goals, both PSG and NPO recordings are carried out ambulatory and simultaneously at patient's home. A portable polysomnograph (Embletta MPR, Natus) is used for standard PSG at home, whereas a portable wrist-worn pulse oximeter (WristOX2 3150, Nonin) is used for ambulatory NPO. In addition, conventional in-lab PSG and attended pulse oximetry are also performed simultaneously in the hospital facilities.
