Abstract

The existence of a cutaneous pressure-induced vasodilation (PIV) has recently been reported. This paper proposes a signal processing methodology to improve PIV knowledge. Temporal variations of laser Doppler signals rhythmic activities are first analyzed on anesthetized rats. The results lead to a method that provides a better PIV understanding.

摘要

最近有报道称存在皮肤压力诱导的血管舒张（PIV）。本文提出一种信号处理方法以增进对PIV的了解。首先在麻醉大鼠身上分析激光多普勒信号节律活动的时间变化。这些结果引出一种能更好理解PIV的方法。
