At what height blood can eject from human vein ? I see, sometime there is direct blood transfer from one person to patient. So sometime blood bottle is kept at certain height and blood is transfered from person to upper bottle and then from that bottle to patient directly. At what height blood can go ?
For example, I had not mentioned before,
What would be the blood pressure outside from body after cutting certain nerve or vein or whatever which carries blood-speedily, when we go inside vacuum chamber ?
Consider any chamber where you will be able to remove air/atmosphere inside it and a person is provided with oxygen cylinder. Now what will be the blood ejection speed outward from the body ? At what height ? You will have to consider atmospheric pressure also when we leave normally on earth. So question is, at what height in vacuum (where there is no pressure from outside world) ?
