When measuring a BP via auscultation of the brachial, I look at the gauge and see the needle start to flicker before I physically hear the Korotkoff sounds.
E.g. I might see the needle flicker at 160 and hear the sounds at 140. Clearly that's quite the difference...
So what do I go by? Technically at the 'flicker', blood is getting past, so therefore the pressure required has been reached.. or am I missing something?
Many thanks
