Validation of a Suprasternal Pressure Transducer for Apnea Classification During Sleep

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

Self-Advising SVM for Sleep Apnea Classification

In this paper Self-Advising SVM, a new proposed version of SVM, is investigated for sleep apnea classification. Self-Advising SVM tries to transfer more information from training phase to the test phase in compare to the traditional SVM. In this paper Sleep apnea events are classified to central, obstructive or mixed, by using just three signals, airflow, abdominal and thoracic movement, as inp...

Factors Affecting Patients’ Adherence to Continuous Positive Airway Pressure Therapy for Obstructive Sleep Apnea Disorder: A Multi-Method Approach

Background: Continuous positive airway pressure (CPAP) is the gold standard therapy for treating obstructive sleep apnea (OSA) disorder. However, patients’ adherence to its regular use is poor. The present study aimed to determine the adherence rate to CPAP therapy by identifying factors affecting its regular use and its associated problems and discomforts among a sample population in Mashhad (...

A Comparative study of four Persian versions of sleep questionnaires for screening obstructive sleep apnea syndrome (OSAS)

Background: Diagnosis of obstructive sleep apnea syndrome (OSAS) is valuable, but it is time-consuming and expensive. Appropriate screening instruments help clinicians select high-risk individuals for further investigations. In the present study, we compared 4 popular instruments used in screening OSAS including Berlin, STOP, STOP-BANG questionnaires, and Epworth Sleepiness Scale (ESS).  ...

Degree of arousal is most correlated with blood pressure reactivity during sleep in obstructive sleep apnea.

We investigated blood pressure (BP) reactivity of obstructive sleep apnea (OSA) during rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep. The influences on BP reactivity of degree of arousal, the lowest O2 saturation (SaO2), and respiratory disturbance (RD) duration were compared. Ten normotensive or borderline hypertensive patients with OSA were studied with one-night poly...
