Answer 1

if too much air gets in the blood it causes what is known as "the bends" and could be fatal.
injecting air into the bloodstream from a syringe has been used as a form of suicide. i'm not sure how much is required.
i know that some insulin users giving themselves shots have accidentally given empty injections, but i don't think they died.

Answer 2

An air embolism, or more generally gas embolism, is a medical condition caused by gas bubbles in the bloodstream. Small amounts of air often get into the blood circulation accidentally during surgery and other medical procedures, but an air embolism which shows symptoms is very rare. Death usually occurs when a bubble of gas becomes lodged in the heart, stopping blood from flowing from the right ventricle to the lungs. (Wikipedia)
Arterial gas embolism is a potentially catastrophic event that occurs when gas bubbles enter or form in the arterial vasculature and occlude blood flow, causing organ ischemia. Arterial gas embolism can cause CNS injury with rapid loss of consciousness, other CNS manifestations, or both; it also may affect other organs. Diagnosis is clinical and may be corroborated by imaging tests. Treatment is immediate recompression.(Merck)
Please see the web pages for more details on Arterial gas embolism (Air embolism).

Answer 3

The person who got injected with air would die. This is why you see doctors holding the needle up, tapping the side, and squirting some of the fluid out of the syringe. This is to make sure that not even the smallest air bubbles are left in the needle.

Answer 4

Venous air embolism (VAE), the entry of gas into the peripheral or central vasculature. Entrapment of large quantities of intravascular gas can lead to severe neurologic injury, cardiovascular collapse, and even death. The factors that determine the subsequent morbidity and mortality in VAE include the rate of air entrainment, the volume of air introduced, and the position of the patient at the time of the embolism. Although very small volumes of air can lead to severe sequelae, it is generally accepted that more than 50 ml of air can cause hypotension and dysrhythmias and more than 300 ml of air can be lethal.

Answer 5

if someone enjected air into someone's veins they would die. the air goes straight to the bloodstream and kills you instantly. possibly have embolism's

Answer 6

thats bad. it WILL kill that air-injected person... it stops blood flow to the brain or heart

Answer 7

dont do this! it causes an air embolism and kills the person immediately!and the results can be seen at autopsy,it would clearly be ruled murder!dont do it!!!!!!!!!!
