Edit: can't find anything regarding what exactly low pressure shouldn't be. Everywhere it says "lower than 120/80" is good. Like okay 0/0 also seems healthy ¯\_(ツ)_/¯

Mean Arterial Pressure is the actual number we use as a guideline. MAP is calculated as 1/3 of the top BP number + 2/3 of the bottom number:

Goal is bare minimum 60, and preferably >65. A BP of 80/40 gives you a MAP of 53, which = no bueno. Your kidneys and brain will not be happy.

I once had 80/40 or 60/40, can't remember exact number, for a very short time. It wasn't too pleasant and judging by the doctor reaction it wasn't supposed to be that low. It was just after a tooth removal, just a bit of overreaction 😅

Thank you for sharing the info, I should memorise the threshold to use it when uncertain if the pressure is too low
