 This is the equation for Ohm's law for fluids Q = ∆P / RQ flowP pressureR resistance Volume of blood that goes through a region per minute Blood flow What is pulmonary arterial pressure? 25/8 Venous pressure in the right atrium and the big veins Central venous pressure This is the formula for Resistance: r = radiusl = lengthn = viscosity Combined resistance of all blood vessels Total peripheral resistance This is the equation for velocity Q = flowA = cross section This is the normal pattern or way that blood flows laminar flowR < 2000 This is the pattern or way that too fast blood flows turbulent flowR > 2000 What do you call a dilated blood vessel, in a bad way haha? aneurysm This is the equation for Tension-Pressure relationship: P = pressurer = radiush = wall thicknessIf 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 Measuring velocity using ultrasound: Vs = speed of soundyeah whatever Pressure-Tension relationship If a heart is dilated, more tension made to keep up the pressureIts bad for the heart AuthorBobopudge ID67503 Card SetCVR9 DescriptionHemodynamics Updated2011-03-31T14:50:01Z Show Answers
