Abstract:
Objective To evaluate the clinical value of Apneagraph(AG200)and CT scan in diagnosing obstructive sleep apnea hypopnea syndrome(OSAHS). Methods Twenty-two moderate and 18 severe obstructive sleep apnea hypopnea syndrome(OSAHS) patients diagnosed by polysomnography(PSG) performed one-night pressure monitoring by Apnea-graph, the apnea hypopnea index (AHI),the site of upper airway callapse and the obstructive proportion of different level. The cross-sectional areas of the pharyngeal wall of retropalate, lingua regions planes were scanned by MSCT scan in the waking state were analyzed. The obstruction levels determined by pressure monitored and found in CT screening were compared. Results Apneagraph and CT scan had good performance in the diagnosis of OSAHS. There was no difference between two methods(P>0.05).Conclusion Apneagraph and CT scan can serve as a useful device to diagnose OSAHS.The diagnostic rate of OSAHS (especially severe OSAHS)can be elevated by combining Apneagraph and CT scan.
