What is the formula for velocity?

Flow/Area (circle)

1

Flow

dP/R

2

Resistance (one vessel, pressure related)

dP/F

3

Single vessel resistance

nL/r^4

4

Passouiles (or however u spell it) equation

[pi*dP*r^4] \ 8nL

5

Turbulent flow

v*d*(p/n)

6

MAP

Pdia + 1/3 (Psys-Pdia)

7

MAP (2)

(CO* TPR) + CVP

8

TPR (1)

(MAP-CVP)/CO

9

TPR (2)

dP/F (subtract lung)

10

Pulse pressure

SV / C

12

Flux (Js)

DA* (dC/dX)

13

Ejection fraction

SV/EDF

14

Pressure Volume Area

SW + PE

15

Stroke Work

SV * MAP

16

PE

area btwn ESV and EDV on left side of cycle

17

Cardiac Efficiency

PVA/O2 consumption

18

Myocardial O2 consumption

Vo2=Q{aO2-vo2]

19

Cardiac Output using O2

CO= Vo2/[aO2-vO2]

20

stroke volume

CO/HR
