Brief 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.

Official Title: Determining a Threshold for the Clinical and Cost-effectiveness of Group Size During Basic Life Support Courses
Actual Study Start Date : December 10, 2018

Estimated Study Completion Date : August 31, 2020

Arm Intervention/treatment
Active BLS- Instructors at the Bern Simulation and CPR- Center (BeSiC), at the Bern University Hospital, Bern, Switzerland. Participants have to oversee a BLS instructional session, where standardized errors are performed by trained volunteers.
Other: errors made in one BLS session
BLS instructors have to oversee a standardized BLS training session, where standardized errors are made by trained volunteers.

Primary Outcome Measures :
  1. The threshold of number of course participants in a BLS educational session [ Time Frame: BLS educational session 10 minutes ]
    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.
