Prediction formulaPurpose This study developed formulas to predict obstructive sleep apnea (OSA) and the Apnea–Hypopnea Index (AHI) in Korean patients with suspected OSA using clinical, anthropometric, and cephalometric variables. Methods We evaluated relevant variables in 285 subjects with suspected OSA...

Sleep apnea hypopnea index (AHI) refers to the number of apneas plus hypopneas per hour of sleep, and is related to the severity of apneas. According to Chicago standards, the severity of apnea is classified into four categories, including normal (AHI<5), mild sleep apnea syndrome (5<AHI...
The Epworth sleepiness scale was applied to each patient at the first visit. If scores were suspicious for obstructive sleep apnea (score ≥ 10), patients were referred for a polygraphy. In case of an apnea–hypopnea index (AHI) ≥ 5 a polysomnography (PSG) was performed. If PSG ...

Body position has been studied in children. While adults tend to have more severe OSA in thesupine position, children have been shown to have a lower apnea hypopnea index in the supine position compared to theprone position. One study investigating the position of infants who died unexpectedly ...

The present study was to investigate the association of aldosterone excess and apnea-hypopnea index (AHI) in patients with resistant hypertension. Patients with resistant hypertension were enrolled and baseline characteristics including plasma aldosterone concentration (PAC) and 24 h-urine aldosterone leve...
Being a public health problem, obstructive sleep apnea–hypopnea syndrome predominance ranges between 9% and 38% with an Apnea–Hypopnea Index (AHI) greater than 5 [1]. However, it is highly underdiagnosed as the OSA is not always accompanied by daytime sleepiness which can leave the sleep-dis...
