Varies: A healthy person can endure 10-15% blood volume loss before hypotensive shock would threaten them. Someone with severe cardiac disease might not survive lesser amounts of blood loss.

Depends: A young person can endure even greater amounts of blood loss without going into hypotensive shock. They may feel light headed and may have orthostatic hypotension.

May be 1-2 liters: An healthy individual can withstand probably upto 1liter rapid loss, but after that it may be difficult. If it is slow bleeding, even if you lose 2-3 liters, the body has time to adjust.
