Systemic vascular resistance

The outlet resistance blood meets as it flows through systemic vessels.

這是什麼

Systemic vascular resistance is the resistance blood meets across the systemic circulation, strongly shaped by small arteries and arterioles.[1]

為什麼重要

When resistance is higher, the same flow needs more pressure to pass through the vascular system.[2,1]

發生異常的根本原因

  • Core relation: Narrower systemic vessels create more outlet resistance; more resistance means blood flow needs a higher pressure gradient to move through tissues.[1,2]

它會影響哪些判斷

  • It is a bridge between vessel tone, blood pressure, afterload, and perfusion context.[1]

解讀陷阱

  • BioConst does not estimate personal SVR from routine blood pressure readings.[1]
