Apnea-Hypopnea Indexes Calculated Using Different Hypopnea Definitions and Their Relation to Major Symptoms

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

Calibration Model for Apnea-Hypopnea Indices: Impact of Alternative Criteria for Hypopneas. [PDF]

Sleep, 2015
To characterize the association among apnea-hypopnea indices (AHIs) determined using three common metrics for defining hypopnea, and to develop a model to calibrate between these AHIs.Cross-sectional analysis of Sleep Heart Health Study Data.Community-based.There were 6,441 men and women age 40 y or older.Three separate AHIs have been calculated, using

Mortality-risk-based apnea–hypopnea index thresholds for diagnostics of obstructive sleep apnea

Journal of Sleep Research, 2019
The severity of obstructive sleep apnea is clinically assessed mainly using the apnea–hypopnea index. Based on the apnea–hypopnea index, patients are classified into four severity groups: non-obstructive sleep apnea (apnea–hypopnea index\ua0< 5); mild (5

Automated Scoring of Obstructive Sleep Apnea and Hypopnea Events Using Short-Term Electrocardiogram Recordings

IEEE Transactions on Information Technology in Biomedicine, 2009
Obstructive sleep apnea or hypopnea causes a pause or reduction in airflow with continuous breathing effort. The aim of this study is to identify individual apnea and hypopnea events from normal breathing events using wavelet-based features of 5-s ECG ...

Impact of Different Criteria for Defining Hypopneas in the Apnea-Hypopnea Index

Chest, 2001
To explore the effect of using different scoring criteria for hypopneas in the scoring of polysomnographic studies: (1) by estimating the level of agreement between apnea-hypopnea index (AHI) scores derived from different scoring methods, and (2) by examining the effect on the point prevalence of disease using different threshold values of the AHI ...

The Sleep Hypopnea Syndrome

American Review of Respiratory Disease, 1988
Abstract We have observed patients who clinically have the obstructive sleep apnea syndrome but have no apneas, instead having recurrent nocturnal hypoventilation. There is disagreement about the definition and significance of such sleep-related hypopneas.
