Abstract(s)
Obstructive sleep apnea syndrome (OSAS) is a sleep-disordered breathing disorder. It consists of a set of symptoms and signs that result from recurrent episodes of intermittent upper airway obstruction. It is estimated that this syndrome is very common; however, its true prevalence is unknown, as it is underdiagnosed.
OSAS is considered a systemic disease with several associated consequences, including cardiovascular and metabolic diseases, making it a public health problem. Polysomnography is the sleep study of choice for the diagnosis of OSAS, but the fact that it is a time-consuming test contributes to the underdiagnosis of this pathology. For this reason, one can opt for the Cardiorespiratory Sleep Study which, despite
being a simpler test, allows for the diagnosis of this syndrome. The manual reading of these tests is one of the aspects that most contributes to their slowness, as well as the inter-observer variability in their reading. From a simplistic perspective, some studies have focused on the automatic analysis of these exams. However, there
have been discrepancies between the two analyses, which can be significant in terms of final diagnosis and consequent therapeutic orientation. The Sleep Unit of the Hospital da Luz Setúbal, based on a sample of 3297 scans performed in 2011-2019, concluded that the automatic analysis may lead to an incorrect diagnosis of OSAS as well as its severity, being important that the diagnosis of this pathology be based
on a manual analysis.
