Vascular tone / vasodilation

The constricted or relaxed state of blood vessels that changes resistance and flow.

これは何か

Vascular tone is the constricted or relaxed state of blood vessels. Vasodilation widens vessels and lowers systemic vascular resistance.[1,2]

なぜ重要か

Changing vessel radius changes outlet resistance, so tone directly affects pressure and tissue blood flow.[2,1]

異常値が生じる根本原因

  • Core relation: When vessels constrict, the outlet narrows and resistance rises; when vessels dilate too much, resistance falls and pressure can drop.[2,1]

どの判断に影響するか

  • It links autonomic reflexes, vascular resistance, blood pressure, temperature, stress, and medication context.[1]

解釈上の注意

  • BioConst does not infer personal vessel tone from a single blood-pressure reading.[1]
