You can die from losing as little as 1 pint (sheer shock on this one), to 4-5 pints putting you in hypovolemia. Now, you can lose even more than that, the threshold comes in that the heart can’t be empty, it kinda stalls the engine so to speak.You could technically lose up to 7 pints, but you would have to have no flow to your arms or legs, and even then you would probably be unconscious. This is affected by age for example a 10 year old has around 7 pints and a newborn has about half a pint however this does vary person to person.
