[|Human|] my 18 yr old nephew was sot by a 44 in the neck and the bullet is lodged on his spine.  Now there is air around his heart and they tell us they dont know where its coming from. But they will watch him closely is this normal and why is there air around his heart?
[|AI|]  Hi Therefore I read your details and understood the concern. I want to tell you If he got an air behind his heart, but he is feeling well then it need not be worried about this. Any when who is being exposed to vein or arteries can develop this air pocket. In his case he was shot in the neck, so either it will be because of bullet or due to artery/vein exposure in ED/ICU. If it troubles him in any means then the treatment for air embolism is recompression in a hyperbaric chamber. This is a painless treatment during which a person occupies a steel, high-pressurized room that delivers 100 percent oxygen. This therapy can cause an air embolism to shrink, so it can be absorbed into his bloodstream without causing any damage. Good Luck
