At the plasma center the machine screwed up and I lost a pint of blood. How will this affect me negatively? I am a 6’ male, 257 lbs with a lean body mass (LBM is more metabolically active so it requires more blood, I assume. I know men have 2 more pints than women though) of 191 lbs so I assume I have about 12-14 pints total since the average male has 10-12 pints.
So will one pint make a difference? How long until I make another pint?
Unlikely to impact on a healthy person of your size in any significant way. Push fluids to be sure. If you bled it out suddenly over a few seconds in front of your own eyes, you might have a significant drop in blood pressure, but if it was due to plasmaphereisis, it’s unlikely.
Did you lose the equivalent of a pint of whole blood, packed cells, or plasma?
The last time I gave blood at the blood center, I asked how much blood is in a typical donation. “Very close to a pint,” was the answer. So, if that’s how much you lost, you are not in trouble at all. It takes a few weeks to replace the platelets and the red and white cells, but the liquid is replaced within a few hours.
Back when I was a blood donor I was literally half your weight and I never noticed the missing pint of whole blood I’d donate each time.
Extra fluids for a couple days, and you’ll shortly replace any lost cells. Like the doc Mercotan said, unlikely to impact you in any significant way.
