用于成人的市售声反射鼻测量计（AR）经改装可试用于婴幼儿。将标准波管用一只内径较小（截面积0．312cm2）的玻璃管替代。在应用于新生儿之前，先在足月死婴的鼻腔应用以确认其精度。声反射鼻面积曲线与鼻模面积数据以及从标本直接测得的容积数据作比较，鼻腔总面积AR与鼻模数
Commercially available reflex nasal gauges (AR) for adults are adapted for use in infants and toddlers. The standard wave tube with a smaller diameter (cross-sectional area of 0.312cm2) glass tube instead. Nasal cavity of full-term infanticide should be used to confirm its accuracy before application to newborn. Acoustic reflectance nasal area curve and nasal mold area data and directly measured from the specimen volume data for comparison, the total nasal area AR and nasal modulus
