Photoplethysmographic Signal to Screen Sleep-Disordered Breathing in Hospitalized Heart Failure Patients: Feasibility of a Prospective Clinical Pathway.

摘要: Abstract Objectives The purpose of this study was to evaluate the plethysmographic signal-derived oxygen desaturation index (ODI) as an inpatient screening strategy identify sleep-disordered breathing (SDB) in patients with congestive heart failure (CHF). Background SDB is highly prevalent among hospitalized CHF but widely underdiagnosed. We evaluated overnight photoplethysmography a possible for CHF. Methods Consecutively admitted high clinical suspicion and ODI ≥5 were offered outpatient polysomnography (PSG), which completed within 4 weeks discharge. PSG considered positive if apnea hypoxia (AHI) was ≥5. A Bland-Altman plot used assess agreement between ODI AHI. Receiver-operator characteristics determined AHI ≥5. Results questionnaire identified 246 282 consecutive symptoms SDB. Of these patients, 105 further evaluation 86 had (mean 17 ± 17). Among 68 underwent showed that 64 (94%) SDB, mean AHI 28. Inpatient correlated well PSG-derived area under curve 0.82 revealed no major bias. Matthew’s correlation coefficient optimal cut-off is 5. Conclusions Screening using targeted identifies cohort prevalence Our provides potentially cost-effective method early detection treatment
