When a cardiac arrest occurs it is vital that bystanders act immediately. As a minimum bystanders should be able to check consciousness, call 112 and perform chest compression of sufficient depth and speed until an ambulance or other professional support arrives. The majority of people however do not have these skills. Courses in Basic Life Support are available in all European countries on average 2 hour including a practice session. Research shows (1) these courses are effective and both immediate and short-term (4-6 months) retention is high. These courses are however a too time-consuming and costly option when our aim is to train the vast majority of people and maintain their skill level. In this presentation we present a minimal online resuscitation training.
