Abstract

When palmar eccrine sweat glands are inactive the potential difference between palmar skin and a prepared forearm site is a function of the ratio of external (electrode electrolyte) and internal (tissue fluid) potassium concentrations. Evidence indicates that this "basal" palmar skin potential changes systematically with changes in ECF K+, and may be used to monitor such shifts, as, for example, in stress.

摘要

当手掌部的外分泌汗腺不活动时，手掌皮肤与备好的前臂部位之间的电位差是外部（电极电解质）和内部（组织液）钾离子浓度比值的函数。有证据表明，这种“基础”手掌皮肤电位会随着细胞外液钾离子浓度的变化而系统性地改变，并且可用于监测此类变化，比如在应激状态下的变化。
