Vaccuum question....?

Your hand will swell up as blood and other fluids are pulled into it. First big blisters will form, then they will fill with blood, then they will pop and you will bleed freely into the vacuum. uming the pump can maintain the low pressure, your blood will boil. Your wound will continue to bleed because blood needs oxygen to coagulate. You could die from the quick loss of blood if it was not stopped.
