Can we truly change from polysomnography to polygraphy in obstructive sleep apnea? A comparison between these to levels of sleep studies in a population of patients with obstructive sleep apnea

Introduction: Polygraphy (PG) or polysomnography (PSG)–sleep studies level III and I, respectively, can be used to diagnose sleep apnea. The first focuses exclusively on respiratory parameters that are analyzed as if the entire study was done with the patient sleeping. The second involves a multi-parameter monitoring, in which respiratory variables are analyzed only during sleep, excluding wakefulness in the apnea/hypopnea index (AHI) and respiratory disturbance index (RDI) determination.
