Air Embolism Veins
Occasional problems: As dr. Simpson says, usually nothing happens when a small amount of air enters the veins. It is trapped in the lung and absorbed. However, if the amount of air is large, it can block blood flow in the lung. Also, if there is a hole in the heart (atrial septal defect), or a so-called "shunt" of blood that bypasses the lung, air can get into the arteries and cause a stroke. ...Read moreSee 1 more doctor answer

The best "treatment" is prevention - like keeping the patients head below the heart. If air embolism occurs we are taught to position patients certain ways and aspirate. ...Read more
Variable: Air embolism through the vein requires higher amount of air to cause death, in the range of 50-100 ml of air injected fast like a ball can cause obstruction in the heart valve like a lock. Arterial air embolism requires very little amount and as little as 1/2 cc of air that goes into the coronary artery can cause a fatal heart attack and 1-2 cc can obstruct flow in the brain. ...Read more
