The influence factors of sound pressure level parameters in patients with simple snoring and obstructive sleep apnea hypopnea syndrom / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To discuss the main influence factors of sound pressure level parameters in patients with simple snoring (SS) and obstructive sleep apnea hypopnea syndrom (OSAHS).@*METHOD@#Eighty-four cases with snoring disease underwent polysomnography and simultaneously snoring sound pressure level recording. The correlations between AHI, age, BMI, abdomen circumference, neck circumference, the lowest oxygen saturation total apnea time and sound pressure level parameters equivalent continuous sound level(LAeq)and maximum sound pressure level(L10) were analyzed.@*RESULT@#LAeq was significantly correlated to AHI (P= 0. 000) and BMI (P= 0. 007), and the odd ratios of AHI and BMI were 5. 74,2. 09 respectively, but it was unrelated to age, abdomen circumference, neck circumference, the lowest oxygen saturation and total apnea time. A significantly association also existed between L10 and AHI(P=0. 000), BMI(P=0. 032), and the odd ratios were 4. 11 and 2. 33 respectively. Other factors had nothing to do with L10.@*CONCLUSION@#The main factors which affect the snoring sound pressure level parameters LAeq and L10 are AHI and BMI.
