Abstract:
Objective To explore the diagnostic value of pulse transit time(PTT) in children with sleep disordered breathing(SDB).Methods Forty eight randomly selected snorers(2-13 years)with SDB were examined by PSG and PTT in the same time. Data obtained were analyzed by different technicians respectively. Statistics and analysis of the data were performed. Results Apnea hypopnea index (AHI),obstructive apnea index(OAI), the lowest oxygen and micro-arousal index were obtained by PSG and PTT.The results was described as M [25 percentile; 75 percentile]:4.9[1.3; 10.1], 4.6 [1.5; 11.8]; 1.2[0.7;4.9], 1.3[0.6;5.0]; 0.93[0.85;0.95], 0.93[0.84;0.95]; 14.5[12.6;16.4], 26.0[17.4;30.6]. The difference of AHI, OAI, and the lowest oxygen were not significant (P＞0.05), while the PTT arousal index detection rate was higher than PSG(Z=-5.19, P＜0.01). There was no significant difference in the diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS) and determination of degree of patient's condition (P＞0.05). PTT could identify upper airway resistance syndrome in children without OASHS. Conclusions Both methods can be used to diagnose SDB. However, PTT is easy to useand suitable for the diagnosis of SDB in children, especially for UARS.
