Similarly one may ask, is an air embolism immediate?
Small embolisms generally dissipate into the bloodstream and don't cause serious problems. Large air embolisms can cause strokes or heart attacks and could be fatal. Prompt medical treatment for an embolism is essential, so immediately call 911 if you have concerns about a possible air embolism.
Also, how much air does it take to cause an air embolism? If an arterial gas embolism reaches the brain, it is referred to as a cerebral embolism and can cause a stroke. An injection of 2-3 ml of air into the cerebral circulation can be fatal. Just 0.5-1 ml of air in the pulmonary vein can cause a cardiac arrest.
Keeping this in consideration, how quickly does an air embolism happen?
You may not have these symptoms immediately. They can develop within 10 to 20 minutes or sometimes even longer after surfacing. Don't ignore these symptoms – get medical help straight away.
What should you do if air embolism is suspected?
Immediately place the patient in the left lateral decubitus (Durant maneuver) and Trendelenburg position. This helps to prevent air from traveling through the right side of the heart into the pulmonary arteries, leading to right ventricular outflow obstruction (air lock).
