General & Family Physician,  's  Response
Hello dear,like to hear such questions.
When empty syringe is injected,air enters the circulatory system and causes a condition called as "air embolism".When reasonably high amount of air enters the blood stream fast,the bubbles(embolus) can block major vessels.If it occur in brain,leads to stroke;in heart,causes heart attack.But usually,such air reaches lung ,and get cleared.Problem arises when lung is bypassed somehow(for eg,by a arterio venou fistula/cardiac shunts).
I hope you got it.Thank you.
