The blood hammer phenomenon is a sudden increase of the upstream blood pressure in a blood vessel (especially artery or arteriole) when the bloodstream is abruptly blocked by vessel obstruction. The term "blood-hammer" was introduced in cerebral hemodynamics by analogy with the hydraulic expression "water hammer," already used in vascular physiology to designate an arterial pulse variety, the "water-hammer pulse."
Famous quotes containing the words blood and/or hammer:
“Your kind doesn’t just kill men. You murder their spirits, you strangle their last breath of hope and freedom, so that you, the chosen few, can rule your slaves in ease and luxury. You’re a sadist just like the others, Heiser, with no resource but violence and no feeling but fear, the kind you’re feeling now. You’re drowning, Heiser, drowning in the ocean of blood around this barren little island you call the New Order.”
—Curtis Siodmak (1902–1988)
“Many hammer all over the wall and believe that with each blow they hit the nail on the head.”
—Johann Wolfgang Von Goethe (1749–1832)
