Blood hammer

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 [cite journal | author = Damsa T. et al. | title = "Blood-hammer" phenomenon in cerebral hemodynamics. | work = Mathematical Biosciences | year = 1976 | volume = 29 | issue = 3-4 | pages = 193–202 ] by analogy with the hydraulic expression [2] "water hammer", already used in vascular physiology to designate an arterial pulse variety, the "water-hammer pulse".
