Obstructive Sleep Apnea Hypopnea Syndrome: A Comparative Study of Cardiopulmonary Exercise Testing Outcomes

Article ID: 4747

Abstract

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a condition characterized by recurrent episodes of respiratory arrest or hypoventilation dur ing sleep, leading to airflow limitation lasting 10 seconds or more [1] . Clinically, it manifests as snoring, intermittent respiratory arrest, frequent nocturnal awaken   ings, increased nighttime urination, poor sleep quality, daytime somnolence, and cognitive decline. Diagnosis relies on polysomnography (PSG), which monitors brain waves, eye movements, and chin muscle tone to assess sleep-wake states, as well as thoracoabdominal movements, oronasal airflow, and blood oxygen saturation to identify apneas and hypopneas. Cardiopulmonary exercise testing (CPET) is an objective, non-invasive method for evaluating cardiopulmonary reserve and exercise tolerance, distinct from conventional electrocardiogram-based exercise tests and static pulmonary function tests [2] . This study aims to explore the cardiopulmonary functional changes in OSAHS patients and the clinical application value of CPET by comparing CPET results between OSAHS patients and healthy adults.
