No, luninous00, it’s not like the movies. Resuscitation now involves the use of CPR and, if available, and AED. But inhaling a “lung full of water” has its own complications. These depend upon whether it is fresh or salt water that is inhaled. In fresh water, the water does not stay in the lungs, but is absorbed into the blood stream due to the salt content of the blood. There, it can cause complications hours later, including the swelling of the red blood cells (RBCs), and their subsequent bursting. This obviously can be life-threatening, even if the person has been resuscitated. For salt water near drowning, there is salt water in the lungs, and it has infectious materials in it. So a lung infection is a real possibility. All near-drowning people need to go to the hospital for at least some observation.
