A Clinical Prediction Formula for Apnea-Hypopnea Index

A Clinical Prediction Formula for Apnea-Hypopnea Index

Objectives. There are many studies regarding unnecessary polysomnography (PSG) when obstructive sleep apnea syndrome (OSAS) is suspected. In order to reduce unnecessary PSG, this study aims to predict the apnea-hypopnea index (AHI) via simple clinical data for patients who complain of OSAS symptoms. Method. Demographic, anthropometric, physical examination and laboratory data of a total of 390 ...

Is Apnea-Hypopnea Index a proper measure for Obstructive Sleep Apnea severity?

Prediction of the apnea-hypopnea index from overnight pulse oximetry.

STUDY OBJECTIVE 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. DESIGN Prediction model developed from 224 patients, validated prospectively in 101 patients from t...

Effect of the definition of hypopnea on apnea/hypopnea index.

The objective of this study was to determine whether different decreases in oxygen saturation (SaO2) or the presence of electroencephalographic arousals (EEGA) in the definition of hypopnea modify hypopnea index and apnea/hypopnea index and the prevalence of obstructive sleep apnea/hypopnea syndrome (OSAHS). A total of 20 polysomnographies performed in patients with OSAHS were analyzed. There a...
