Secretion of alpha-amylase by the human parotid gland increased significantly during eight days of hyperbaric exposure. This hyperactivity of the parotid gland presumably resulted from increased autonomic nervous system (ANS) activity attributable to (1)psychological stress in the form of anticipation; (2) dive-related factors, i.e., hyperoxia, PN2, physical stress; or (3) a combination of both. The etiology of the effect must await additional studies, but a consistent and significant elevation in alpha-amylas secretion was found. This previously undescribed effect of hyperbaric exposure indicates that parotid alpha-amylase sampling holds promise as a noninvasive means of monitoring physical and psychological stress, and as an indirect measure of ANS tone.
在高压暴露的八天期间，人类腮腺的α淀粉酶分泌显著增加。腮腺的这种机能亢进大概是由于自主神经系统（ANS）活动增加所致，这归因于：（1）预期形式的心理压力；（2）与潜水相关的因素，即高氧、PN2、身体压力；或（3）两者的结合。该效应的病因必须等待进一步研究，但发现α淀粉酶分泌持续且显著升高。这种以前未描述过的高压暴露效应表明，腮腺α淀粉酶采样有望作为监测身体和心理压力的一种非侵入性手段，以及作为ANS张力的一种间接测量方法。
