We had the CPR / First Aid training at the office. Every employee is now ready to handle different kinds of emergency situation. That was the first time for me to see an AED and demonstrate it. I learned that AED should be used only in case someone lose conscious, breathing and heart beating. When I was in Japan, there was a criticism towards school teacher who didn’t use AED because the student had conscious, breathing and heart beating. AED in Japan might have a function to diagnose the necessity of electrical shock, according to the instructor of our CPR class. However, I though it is too difficult to catch up with the latest technology and fully utilize it. klingt das natürlich?
