Shock is a syndrome caused by a disorder in systemic perfusion leading to cellular hypoxia, inadequate tissue oxygenation, and organic dysfunction. To approach the shock, the following sequence must be followed: recognize its presence, preferably in the initial phase; establish measures of general support; establish the etiology of the shock; and establish early correction of the primary cause (stop the bleeding). During care in the emergency room, to evaluate these signs quickly and efficiently, one should observe the pulse, skin color, and level of consciousness. Other signs of shock are oliguria, hypotension, tachypnea, hypothermia, and reduction of pulse pressure. There are several types of shock: hemorrhagic, neurogenic, cardiogenic, septic, and obstructive.
