Apnea–hypopnea duration may be a better choice rather than apnea–hypopnea index for forecasting complications in OSAS

CRANIO®
Mean apnea-hypopnea duration (AHD) is the mean duration of apnea-hypopneas experienced during sleep and was found as an indicator of blood oxygenation. The aim of this study was to compare and define the differences in clinical, demographic and polysomnographic characteristics of obstructive sleep apnea (OSA) patients in long and short AHD groups and ...

Prediction of the Apnea-Hypopnea Index From Overnight Pulse Oximetry *

Chest, 2003
s: To compare the relative usefulness of the different indexes derived from pulse oximetry in the diagnosis of obstructive sleep apnea (OSA), and to determine if a combination of these indexes improves the prediction of the apnea-hypopnea index (AHI) measured by polysomnography.Prediction model developed from 224 patients, validated prospectively in ...

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 ...

Continuous analysis and monitoring of snores and their relationship to the apnea‐hypopnea index

The Laryngoscope, 2010
AbstractObjectives/Hypothesis:We used a new automatic snoring detection and analysis system to monitor snoring during full‐night polysomnography to assess whether the acoustic characteristics of snores differ in relation to the apnea‐hypopnea index (AHI) and to classify subjects according to their AHI.Study Design:Individual Case‐Control Study.Methods ...

The relationship between esophageal pressure and apnea hypopnea index in obstructive sleep apnea-hypopnea syndrome.

Sleep research online : SRO, 2001
Severity of negative esophageal pressure (Pes) and apnea hypopnea index (AHI) were investigated in 34 patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). The OSAHS patients were diagnostically classified as having obstructive sleep apnea syndrome (OSAS) or upper airway resistance syndrome (UARS).

Variability in the Apnea-Hypopnea Index and Its Consequences for Diagnosis and Therapy Evaluation

Respiration, 2008
<i>Background:</i> The apnea-hypopnea index (AHI) is frequently used to recognize obstructive sleep apnea (OSA) and to evaluate therapy. <i>Objectives:</i> The aim of this study was to determine the AHI variability during a 10-week period, and to discuss its consequences for diagnosis and therapy evaluation. <i>Methods:<

The Correlation Among Obesity, Apnea-Hypopnea Index, and Tonsil Size in Children

Chest, 2006
The correlation between obesity and severity of obstructive sleep apnea (OSA) is well established in adults, but data are inconsistent in children. We hypothesized that there is a significant correlation between the degree of obesity and the severity of OSA in children.We retrospectively reviewed records of weight, height, history, and polysomnography ...

Apnea-hypopnea index estimation from spectral analysis of airflow recordings

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
This study focuses on the analysis of airflow (AF) recordings to help in sleep apnea-hypopnea syndrome (SAHS) diagnosis. The objective is to estimate the apnea-hypopnea index (AHI) by means of spectral features from AF data. Multiple linear regression (MLR) was used for this purpose.

Tirzepatide for the Treatment of Obstructive Sleep Apnea and Obesity.

New England Journal of Medicine
BACKGROUND Obstructive sleep apnea is characterized by disordered breathing during sleep and is associated with major cardiovascular complications; excess adiposity is an etiologic risk factor. Tirzepatide may be a potential treatment.
