Heat attacks are among the most common causes of death. Currently, only about 10% of those affected survive. Applying CPR during the first few minutes is crucial and could save up to 1,000 lives. Wednesday, October 16, was “World Restart a Heart Day” and at the Johannes Kepler University alone, over 200 people tried their hand and tested their CPR skills on a dummy. These skills could increase a person’s chances of survival by over 70%.
