When measuring the blood pressure nurses often say numbers like”120 on 80″. What exactly do those numbers mean and why do you die when they coincide?

Answer 1

OP asked what it means if the BP is the same, not what happens when your BP is the high. In short, if the pressure in your blood vessels is the same when the heart is contracted from when it isn’t (basically the pump vs the non pump) then blood isn’t moving through the blood vessels.

You need positive pressure to move any liquid through any tube, if the pressure in the tube is the same when the pump is on from when the pump is off then you can conclude that while the pump is in the “ON” position it isn’t actually moving any liquid.
