Obstructive Sleep Apnea-Hypopnea Syndrome
2006Obstructive sleep apnea/hypopnea syndrome (OSAHS) is characterized by recurrent episodes of partial or complete upper airway collapse during sleep that is highlighted by a reduction in, or complete cessation of, airflow despite documented on going inspiratory efforts.

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 ...

How Important Is the Differentiation between Apnea and Hypopnea?
Respiration, 2009Apnea and hypopnea during sleep are often viewed as different expressions of the same sleep-related breathing disorder. In our point of view, both symptoms are two different entities which can occur in the same patient. We discuss the hypothesis that sleep apnea is a disorder associated with recurrent arousals and chronic activation of the sympathetic ...

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 ...

The accuracy of BPAP determined apnea-hypopnea index
4.2 Sleep and Control of Breathing, 2015Purpose: Bilevel positive airway pressure (BPAP) devices do not only titrate BPAP pressures but also measure residual respiratory event. The aim of this study is to determine the accuracy of BPAP derived residual apnea-hypopnea index (AHI). Methods: We studied 100 patients who underwent in laboratory overnight PSG (polysomnography) using BPAP ...

Evaluation of an alternative definition for the apnea-hypopnea index
2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010The apnea-hypopnea index (AHI) plays a major role in determining whether a patient suffers from SAHS, as well as in evaluating the severity of his/her condition. To obtain this index the number of apneas and hypopneas that the patient has experienced during his/her sleep is calculated, and the result is divided by the number of hours of sleep.
