Pericardial tamponade
Jarda, 62 years old, goes hunting with a group of hunters. While shooting at a hare with a shotgun, Jarda suddenly falls to the ground. One of the nearest hunters runs to him and can see that Jarda is holding his left arm, which is bleeding. As Jarda takes off his coat, he screams in pain and there is blood spraying from his left arm. How would you behave in this situation?
You stop the bleeding by applying pressure on the wound and call an ambulance.
As the first option to stop the bleeding you use an improvised tourniquet (e.g. a trouser belt) and call an ambulance.
At first you disinfect the wound with 52% alcohol, then stop the bleeding by applying pressure on the wound and finally you call an ambulance.
