The American Academy of Sleep Medicine (AASM) recommends that hypopneas be
identified using a definition that is based on a≥ 30% decrease in airflow associated with a≥ …

Study Objectives: There is uncertainty on best approaches for defining apnea-hypopnea
events. To clarify the contributions of desaturation vs arousal to defining hypopneas, we …

Study Objectives: In February of 2023, the American Academy of Sleep Medicine issued a
“recommended” way to score hypopneas using 1A criteria (scoring of hypopneas using a≥ …

Study objectives Obstructive sleep apnea (OSA) diagnosis relies on the Apnea-Hypopnea
Index (AHI), with discrepancies arising from the 3% and 4% desaturation criteria. This study …

Sex disparities are common in all of medicine due to under-representation of women in
biomedical research. This has led to male-centric assumptions about disease defining …

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 …

Background: Studies have established that OSA defined using a hypopnea definition
requiring a≥ 4% oxygen desaturation (AHI4%) is associated with cardiovascular (CVD) or …

Study Objectives: Some prior studies have demonstrated an increase in mortality associated
with obstructive sleep apnea (OSA) utilizing a definition of OSA that requires a minimum 4 …

Abstract Purpose of Review This review explores recent investigations into the clinical
impact of different apnea–hypopnea index (AHI) scoring criteria, namely the minimal oxygen …
