Performing emergency procedures aimed at preserving (at least partially) the cardiac and pulmonary functions.
The treatment includes external heart massage, by which sort of “squeezing” of the heart from outside is performed. By this squeezing partial filling and emptying of the heart is achieved.
In addition, resuscitation includes artificial ventilation that preserves oxygen vs. carbon dioxide exchange, which is the normal function of the lungs.
The term advanced resuscitation refers to medical treatment and electrical shock applied together with basic resuscitation procedures.
