All our customers are offered a free course in the use of defibrillators and cardiopulmonary resuscitation (CPR), where we can either travel to the customer's home or business, or it can be taken online. We recommend completing the course, but we cannot demand it, and there is no longer a requirement for it in Norway. In the past there was a requirement for a course, but the practice was stopped as it was better for someone to try to use a defibrillator, rather than to do nothing in connection with a cardiac arrest. Defibrillators on the market today are much better than before as they come with instructions. For companies, on the other hand, HSE is a requirement. It is important that the knowledge exists in the company, even if they have invested in defibrillators or not.
