What are symptoms of two liter loss of blood?

Answer 1

Two liter blood loss would be close to half the volume of an adult human. It'd be a life-threatening situation and the victim would be severely anemic, probably unconscious. If not you can expect paleness, weak pulse, and very low blood pressure.

Answer 2

Typically not much (based on blood donations- this is how much they take for a donation).

I experienced a feeling of being faint after they removed the needle for blood donation. The edges of my vision became dim. I became very sweaty and clammy. I found it hard to concentrate. The staff put the bed so that my feet were up, placed damp cloths on my head and arms and neck and had a fan on me. I could barely hear anyone but I was able to hear a thumping noise that was going very fast, I thought it was the machine beside me but it was probably my own heart as I couldn't really hear the people around me. After a little bit my hands and legs had pins and needles and so did my the lower half of my face. They had to keep reminding me to breath deeply and wiggle my fingers and toes. It took about 15 minutes for this feeling to go away and once I felt cold they let me drink some juice. In the recovery area, I felt nauseous, I tried to eat some cookies but they made me feel sick. Juice and water helped me feel better. After an hour I felt sick again (upset stomach and sweating and the feeling of being faint) so I laid down on the couch and they put damp cloths on me and a fan again. They sent me home in a cab and I simply felt very tired after that. Laying down helped and drinking a lot of water and eating a large meal with all the food groups in helped.

I've been told this is not uncommon but is considered a worse reaction than usual because it took so long to recover.

Hope this helped.
