Learning basic information from erste hilfekurs is very important because it can be the only way to save somebody’s life. A stroke is an acute disorder of the cerebral circulation. It occurs when a blockage or rupture of blood vessels in the brain occurs. The blood supply to the large hemispheres is disrupted, starving the neurons and killing them.
Two types of stroke are distinguished in the Erste-Hilfe Kurs München: ischemic and hemorrhagic. The most common type is ischemic (more than 80% of cases). It begins because of the narrowing and blockage of blood vessels in the brain. Blood clots and foreign bodies (including air bubbles from injections) that have entered the bloodstream contribute to the circulatory disorder.
Signs of a stroke

- headache, which may be accompanied by nausea and vomiting;

- disturbing sensation in the arms and legs;
- unconscious slurred speech;
- visual disorders (blurred vision, narrowing of visual fields, strabismus).
While you are waiting for the ambulance to arrive, there are some simple rules that can significantly help a stroke patient:
- Always make sure that the patient can breathe. If you find respiratory distress – you need to free the airway by laying the patient on his side and clearing the mouth cavity;
- It is important to measure blood pressure and glucose, if possible. The recorded readings should be recorded and reported to the doctors on arrival;
- Position the patient in a comfortable position, unbutton the shirt collar, raise the head slightly, and arrange for fresh air;
- It is important to understand when a stroke has occurred, especially if the patient has already been found with signs of a stroke. Try to recall the last time you saw the patient without signs of a stroke before the doctors arrive;

- You should also remember from the erste hilfe seminar, that in no case it is not necessary to drink or feed the patient. This can only aggravate his condition.
