是perfusion>>灌注

血流通常用blood flow來翻譯

但其實意義是一樣的

維基裡面的英文說明還不錯(中文為三寶媽的翻譯及說明)

http://en.wikipedia.org/wiki/Perfusion

Perfusion ("F") can be calculated with the following formula(灌注量可由下列公式計算),

where Pa is mean arterial pressure(平均動脈壓),

Pv is mean venous pressure(平均靜脈壓),

and R is vascular resistance(血管阻力):

The term "PA - Pv" is sometimes presented as "ΔP", for the change in pressure.(PA-Pv即動靜脈壓差,可用ΔP表示,等於其壓力變化)

The terms "perfusion" and "perfusion pressure" are sometimes used interchangeably(可替換), but the equation(方程式) should make clear that resistance can have an effect on the perfusion, but not on the perfusion pressure.

灌注量及灌注壓這兩名詞有時可以替換,但該方程式裡只能使用"灌注量"(單位不同)

而維基裡面剛好也有blood flow的公式,其實就是perfusion!!

http://en.wikipedia.org/wiki/Blood_flow

F = blood flow 血流量

P = pressure 壓力

R = resistance阻力

ν = fluidviscosity 液體(血液)黏滯性

L = length of tube管腔(血管)長度

r = radius of tube 管腔半徑
