Ok. I know it's a cartoon joke from Beavis and Butt-Head. On season 2, Blood Pressure episode, Beavis at age 15ish gets in a blood pressure machine and after fighting with it for several minutes, gets released from it by a pharmacist. The blood pressure machine reads "400/300" which was dangerously high for a boy his age. The highest recorded was 230 / 140 stage 4 high blood pressure.
Is it even humanly possible to reach that blood pressure?

1] Any human would have a stroke and/or a heart attack before reaching that pressure.
2] don't think most machines can measure a BP that high

No, the blood vessels and th heart cannot withstand that kind of pressure.
Almost all the blood vessels will rupture within a few seconds of encountering the pressure this high.
P.S
To Brad : Capillaries would be the least of your concern, according to Laplace's Law, the larger the radius of a vessel, the more tension its wall faces under a given pressure. The first of the blood vessels to burst will be the heart and the aorta and the larger veins (I know it sounds contradictory, the heart muscle being very strong, but thats the way it happens.) Also the blood density need not increase, vaso-constriction will also increase in pressure. If the blood is cement like, there won't be any blood flowing and hence there wont be ANY pressure on the wall (Bernoulli's Theorem)

On a physiological basis, no, this would not in any possible way be possible. The big issue here would be capillaries and arteries more than veins (being capacitance vessels). Capillaries, you must realize, are a SINGLE layer of endothelial cells. What you're asking is that the body take up to 8 psi. Do you think a square inch of cells could take the weight of a baby? Or on a larger scale, 64 square inches, (8 in x 8 in) could take 512 lbs? Not to mention the fact of how much blood it would take to reach this. The blood would have to be incredibly dense to a point where it was nearly cement-like in density. On top of ALL of this, the pressure on your vital organs would be so much that it would crush any living tissue surrounding.
Point being: You would die. Immediately.

The highest I had personally taken by machin and then rechecked manually was about 270/ 100. The pt had high blood pressure and I believe was a dialysis patient. They always have high bp.

no, you would literally explode
