If a person gets swelling of brain or lungs what we should do at that point?

Answer 1

For the brain, the cause or etiology of the swelling will obviously be a factor, as controlling the cause is as important as treating the effect. For instance, bacterial infection will call for antibiotics. That said, various drugs like Decadron (dexamethazone -- a glucosteroid) can be used to reduce swelling of the brain. If it's not controllable with medication, placement of a shunt may be required. In extreme cases, trepanation or removal of a circular bone plug from the skull may be called for. In the case of post-drowning cerebral edema, inducing coma by reducing the body;'s core tmerpature, and then slowly raising it over days has been effective at reducing swelling. There is no first aid procedure I can think of that addresses this issue. Inflamation of the lungs is less critical and is usually controlled with the application of steroids. This again is not typically a first aid situation, and very few first responders are able to make this diagnosis, allowed to prescribe this medical course, or even carry this medication.
