Searches for the effectiveness of the cervical auscultation to the swallowing impaired person

受试者均为健康人，年龄不超过50岁，有吞咽障碍者20例。对吞咽前后(呼出空气或吸入空气)的性质、长度、声压、呼吸音、吞水5ml左右的吞咽声产生时间等进行了分析，结果表明，无吞咽障碍的健康人吞咽声较短，但长度和声压个体差异较大。吞咽前后的吱吱声的性质是清楚的，吞咽之后，呼吸迅速重新开始，以确定产生的时间。至于吞咽后的呼吸，也有很多人呼出了气。吞咽重新开始后，呼吸时间的个体差异很大。

The subjects were healthy persons who did not have 50-year-old from 20 swallowing impaired. The properties, length, acoustic pressure, breath sound of before and behind the deglutition (expired air or inspired air), and the generated timing of the swallowing sound at one time swallowing of water about 5ml were analyzed with subjects.As a result, a short, plain swallowing sound was obtained in the deglutition of the healthy person who did not have the swallowing impaired, but both length and acoustic pressure individual variations were large. Properties of the creaking sound before and behind the deglutition were clear, and after the deglutition, breath was promptly restarted as for the generated timing. As for breath after the deglutition, there were a lot of people of the expired air. The individual variation of timing that breath after the deglutition restarts was large.
