The effects of viscosity, taste, and nectar-thick liquid bolus volume on swallowing apnea duration (SAD) were examined.
Twenty-two adults, comprised of 10 males and 12 females, participated. SAD was assessed via nasal airflow during swallow conditions of viscosity (thin liquid, thick liquid, and puree), taste (water, apple juice, lemon concentrate), and nectar-thick liquid bolus volumes (5, 10, 15, and 20 mL) across three trials.
A significant main effect of nectar-thick liquid bolus volume was found (P < 0.05). Viscosity and taste were not significant.
SAD increased with increases in bolus volume; however, neither changes in bolus viscosity nor changes in taste affected SAD.
These findings indicate that since viscosity was not significant, the normative data previously published (by this PI) with 60 healthy adults stratified by age and gender can be utilized for comparison to disordered swallowing without regard to the bolus viscosity being used.

研究黏稠度、味道和花蜜状浓稠液体团块体积对吞咽呼吸暂停持续时间（SAD）的影响。
22名成年人参与研究，其中男性10名，女性12名。通过在三次试验中分别改变黏稠度（稀液体、浓稠液体和泥状食物）、味道（水、苹果汁、浓缩柠檬汁）以及花蜜状浓稠液体团块体积（5、10、15和20毫升）的吞咽条件下测量鼻腔气流来评估SAD。
发现花蜜状浓稠液体团块体积有显著的主效应（P < 0.05）。黏稠度和味道无显著影响。
SAD随团块体积增加而增加；然而，团块黏稠度的变化和味道的变化均不影响SAD。
这些发现表明，由于黏稠度无显著影响，此前由该首席研究员发表的、按年龄和性别分层的6０名健康成年人的标准数据可用于与吞咽障碍进行比较，而无需考虑所使用的团块黏稠度。
