AG200 and polysomnography in patients with obstructive sleep apnea-hypopnea syndrome / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To study the clinical value of polysomnography (PSG) and ApneaGraph (AG200) in the diagnosis evaluation of obstructive sleep apnea hypopnea syndrome (OSAHS).@*METHOD@#From January to December in 2012, 67 OSAHS patients diagnosed by PSG were examined by AG200. The apnea hypopnea index (AHI), hypopnea index (HI), apnea index (AI), the lowest oxygen saturation (LSaO2) was were detected and the results were analyzed statistically.@*RESULT@#Significant differences were observed in AI, AHI, LSaO2 between AG200 and PSG (P 0.05). AHI, HI and LSaO2 was were significantly correlated between AG200 and PSG (r = 0.870, 0.743, 0.374, 0.716, P < 0.01).@*CONCLUSION@#AG200 could not replace PSG but could identify the level of upper airway obstruction.
