Quantification of the loudness of snoring according to Watch-PAT-200 and its relationship with the severity of obstructive sleep apnea syndrome

Abstract

Purpose of the study: Evaluate the capabilities of Watch-PAT-200 in obtaining data to determine the relationship between the loudness of snoring and the severity of obstructive sleep apnea syndrome (OSAS). Material and methods: From 2017 to 2019, 208 patients with complaints of nocturnal snoring were examined. Apnea / hypopnea indices (AHI) and respiratory distress index (RDI) were assessed. The study was carried out on a Watch-PAT-200 portable device (Itamar Medical, Israel). The average volume of snoring (dB) and the proportion (%) of sleep time with the intensity of snoring over 50.60 and 70 dB were measured. The correlation of the obtained data with the AHI and RDI indices is estimated. Results: During the study, it was found that the volume of snoring increases as the severity of OSAS increases, therefore, the volume of snoring can be an indicator of the severity of OSAS. There are ample opportunities for screening diagnostics of the loudness of snoring with the subsequent consultation of a somnologist and timely prescription of treatment. Due to the objectivity of the obtained data and ease of use, the Watch-PAT-200 device can be used in outpatient practice for screening diagnostics of snoring and OSAS in the population.
