  1. This is the equation for Ohm's law for fluids
    • Q = ∆P / R
    • Q flow
    • P pressure
    • R resistance
  2. Volume of blood that goes through a region per minute
    Blood flow
  3. What is pulmonary arterial pressure?
    25/8
  4. Venous pressure in the right atrium and the big veins
    Central venous pressure
  5. This is the formula for Resistance:
    • Image Upload 2
    • r = radius
    • l = length
    • n = viscosity
  6. Combined resistance of all blood vessels
    Total peripheral resistance
  7. This is the equation for velocity
    • Image Upload 4
    • Q = flow
    • A = cross section
  8. This is the normal pattern or way that blood flows
    • laminar flow
    • R < 2000
  9. This is the pattern or way that too fast blood flows
    • turbulent flow
    • R > 2000
  10. What do you call a dilated blood vessel, in a bad way haha?
    aneurysm
  11. This is the equation for Tension-Pressure relationship:
    • Image Upload 6
    • P = pressure
    • r = radius
    • h = wall thickness
    • If a vessel has an aneurism (dilation) then the tension will rise. Now if there's a sudden increase in pressure you can blow up this vessel. Ouch
  12. Measuring velocity using ultrasound:
    Image Upload 8
    • Vs = speed of sound
    • yeah whatever
  13. Pressure-Tension relationship
    • Image Upload 10
    • If a heart is dilated, more tension made to keep up the pressure
    • Its bad for the heart
