A Comparison of Apnea–Hypopnea Indices Derived from Different Definitions of Hypopnea
American Journal of Respiratory and Critical Care Medicine, 1999We examined the effects of arousal- and desaturation-based scoring criteria on the apnea-hypopnea index (AHI) and on the measured prevalence of obstructive sleep apnea (OSA). Ninety-four randomly selected patients underwent overnight polysomnography.

Arousal-based scoring of obstructive hypopneas
Current Opinion in Pulmonary Medicine, 2021Purpose of review Obstructive sleep apnea in adults is diagnosed by an apnea–hypopnea index (AHI) above five (at least five apneas and/or hypopneas per hour of sleep). Though the definition of apneas has remained stable, the scoring criteria for hypopneas has varied throughout the years.

The ethics of hypopnea scoring
Journal of Clinical Sleep MedicineIn February of 2023, the American Academy of Sleep Medicine issued a "recommended" way to score hypopneas using 1A criteria (scoring of hypopneas using a ≥ 3% oxygen desaturation from pre-event baseline) that is at odds with the Centers for Medicare & Medicaid Services mandate of scoring hypopneas using a ≥ 4% oxygen desaturation from pre-event ...

Sleep and Breathing, 2004
A major problem in the discussion of sleep-disordered breathing is caused by the use of different criteria to define its terms. Hypopnea is a good example of this: there is no consensus about its definition yet. In our study, the diagnosis value of apnea-hypopnea indexes (AHIs) determined by different hypopnea definitions was evaluated. The 90 patients

Sleep and Breathing, 2009
In the interest of improving inter-rater reliability and standardization between sleep laboratories, hypopnea definitions were recently changed to place less emphasis on arousal scoring and more emphasis on oxygen desaturations. We sought to determine whether these changes would affect detection and treatment of OSAHS in lean patients-a group known to ...

Objective: In this paper, we propose a convolutional neural network (CNN)-based deep learning architecture for multiclass classification of obstructive sleep apnea and hypopnea (OSAH) using single-lead electrocardiogram (ECG) recordings. OSAH is the most

Sleep apnea is a sleep disorder characterized by abnormal breathing patterns during sleep, and affecting 2-4% of the adult population. If left untreated, it increases the risk of heart attack, stroke, diabetes, depression and early death.

Choice of Oximeter Affects Apnea-Hypopnea Index
Chest, 2005Current Medicare guidelines include an apnea-hypopnea index (AHI) > or = 15 events per hour, in which all hypopneas must be associated with 4% desaturation, to qualify for reimbursement for therapy with continuous positive airway pressure (CPAP). The present data demonstrate the effect of pulse oximeter differences on AHI.Prospective study, blinded ...
