After arriving at the location of an accident, victims must be revived. The method to revive them is random.
Shock Paddles - move the Left and Right Analog sticks up and down in opposite directions (move the mouse up and down on PC) to charge them, and then press both trigger buttons (left and right mouse buttons on PC) to shock the victim.
Chest Compressions - move the Left and Right Analog stick (mouse on PC) up and down simultaneously.
There is a 2 minute countdown, with a time bonus added after each level. Between each level, there is a 30 second timer to return to the same ambulance. Each level ends after reaching the quota to be saved, regardless of if there are other victims at the scene.
