Study summary

Basic Life Support (BLS) is important for outcome in cardiac arrest.Therefore, it is crucial to improve the quality of education in resuscitation training. Better training will eventually lead to more effective CPR skills in course participants. BLS courses in both international resuscitation associations (European Resuscitation Council and American Heart Association are typically taught in small groups of 6 participants. In reality group sizes of up to 10 participants are used, because these courses are highly demanded and cost intensive. There is no evidence for the effective group size to be clinical and cost effective. Therefore the investigators perform this prospective study to determine the maximum number of participants an instructor can oversee without missing more than 20% of errors made during an instructional BLS session.

What researchers measure

Primary outcomes

  1. The threshold of number of course participants in a BLS educational session

    How many volunteers can be overseen by one instructor who still is able to correctly identify and correct serious BLS errors of all course participants.
