Effects of Age on DBP, SBP and HR
|
DBP 70mmHg 20 years to 85mmHg 60 years
SBP 120 mmHg 20 years to 160mmHg 70 years HR rest doesn't change, exercise changes from 200bt per minute for young to 160bt per minute for old. |
Blood Flow= pressure difference/Resistance
Blood Flow is affected by Viscosity and Radius (r4) Transmural Pressure Pinside-Poutside Haematocrit, Temperature and Low Blood Flow may alter viscosity. Arterioles are resistance vessels, Greater diameter change causes greater change in blood flow (consider in Drugs). |
