Assessing the Impact of Asthma on Cardiopulmonary Metrics in Patients with Obstructive Sleep Apnea

Abstract

This study explores the relationship between obstructive sleep apnea (OSA) and asthma, focusing on the impact of asthma attacks on nocturnal cardiopulmonary metrics in individuals with moderate OSA. Polysomnography data from 38 subjects with and without asthma attacks were analyzed to extract pre- and post-sleep metrics related to heart rate, heart rate variability, oxygen saturation, and hypopnea events. A significant difference was found in the percentage of time spent in Stage 2 of non-rapid eye movement sleep between subjects with and without asthma. Additionally, significant differences were found in arterial oxygen saturation pre- and post-sleep in the non-asthma group. Future research should further explore temporal patterns and variations across sleep stages, apnea events, and hypopnea events to better understand the intricate relationship between asthma and OSA.
