Abstract:
OBJECTIVE:To investigate the relevance and clinical value of synchronous monitoring with Apnea Graph (AG) and micro movement sensitive mattress sleep monitoring system (MSMSMS) for the patient with obstructive sleep apnea-hypopnea syndrome before surgery.
METHOD:One hundred and fifteen patients diagnosed as OSAHS by PSG were synchronous examined by two methods: MSMSMS and AG with continuous upper airway pressure recording at night in Peking Union Medical College Hospital. The apnoeic and oxygen desaturation events during sleep determined by the two methods were compared. The correlation between MSMSMS and AG were analyzed.
RESULT:According to the OSAHS severity grading: the mild, moderate and severe were 6, 16, 93 for AG and 8, 26, 81 for MSMSMS respectively, and the hypoxemia severity grading:the mild, moderate, severe were 14, 70, 27 for AG and 6, 72, 37 for MSMSMS respectively. There were no statistically difference in the severity grading of OSAHS and hypoxemia during sleep determined by AG and MSMSMS. According to the parameters of the two methods, the AHI are (51.5 +/- 21.2) times/h (x +/- s, similarly hereinafter) and (48.1 +/- 24.2) times/h, r = 0.947; the LSaO2 are 0.736 +/- 0.110 and 0.710 +/- 0.108, r = 0.935; the correlation coefficient (r) of apnea index and obstructive apnea and hypopnea index were 0.856 and 0.841, P < 0.01 respectively, the data monitored by the two methods is positively correlated.
CONCLUSION:There is no significant difference in determining the severity of OS AHS between the AG and MSMSMS. The two methods had good correlation in respiratory disturbance index and oxygen decline index, and revealed well-prospects of preoperative assessment in patients with OSAHS.
