Background Perceived sleep quality may play an important role in diagnosis and therapy for
obstructive sleep apnea (OSA). However, few studies have assessed factors that are …

Study objectives This analysis determined the association between obstructive sleep apnea
(OSA) with hypopneas defined by a 3% O 2 desaturation or arousal (3% A), but not by a …

Purpose Obstructive sleep apnea (OSA) is a risk factor for cardiovascular disease. Strong
associations have been reported among sleep duration, hypertension, obesity, and …

Purpose The relationship between the severity of the apnea-hypopnea index (AHI) and the
quality of life (QOL) in patients with obstructive sleep apnea (OSA) has been inconsistent in …

Background and Objectives: Poor sleep quality in patients with obstructive sleep apnea
(OSA) may be associated with different clinical and polysomnographic features. The aim of …

Introduction: This study aimed to determine the impact of obstructive sleep apnoea (OSA) on
quality of life (QOL) and evaluate the utility of polysomnographic parameters in reflecting …

Study Objectives: The aim was to investigate how the severity of apneas, hypopneas, and
related desaturations is associated with obstructive sleep apnea (OSA)-related daytime …

To evaluate whether the percentage of total sleep time spent with apnoea and hypopnoea
duration time (AHT%) is better than the apnoea-hypopnoea index (AHI) for the assessment …

Purpose To explore the role of the mean apnea–hypopnea duration (MAD) and apnea–
hypopnea duration per hour (HAD) in hypoxemia and evaluate whether they can effectively …

OBJECTIVE: Currently accepted guidelines categorize obstructive sleep apnea (OSA)
severity according to the Apnea–Hypopnea Index (AHI). However, it is unclear how to best …
