Polysomnography and ApneaGraph in patients with sleep-related breathing disorders.

2007

<i>Purpose:</i> To evaluate whether ApneaGraph (AG) and polysomnography (PSG) deliver comparable results in patients with sleep-related breathing disorders. <i>Procedures:</i> A prospective study was performed, which included 14 patients with obstructive sleep apnea syndrome. Apnea-hypopnea index (AHI), hypopnea index (HI), apnea index (AI), obstructive, central and mixed apnea, oxygen saturation (SaO<sub>2</sub>), pulse and body position were simultaneously assessed by PSG and AG in each individual. <i>Results:</i> There was a good correlation between measurements of AG and PSG for AHI, pulse, SaO<sub>2</sub>, body position and ce…
