Purpose of this study: Basic Life Support (BLS) remains crucial for improving survival after cardiac arrest. Despite all efforts, its quality is often insufficient. The CPR-training at the Medical University of Vienna consists of 4 progressive courses at different stages during the medical curriculum. The aim of our study is to evaluate the progress of chest compression-only (CCO) cardiopulmonary resuscitation (CPR) quality by medical students using an automated external defibrillator (AED). This study provides the baseline for further documenting the development of CPR-quality throughout the medical education program. Materials and methods: In their first weeks of University, 455 medicine students were instructed to follow the instructions of an AED to perform CCO single-rescuer BLS on a manikin (Ambu Man C, Ballerup, Denmark). CPR-quality was assessed over 4 min. The adherence to the ERC-BLS algorithm and proper AED use were documented. The primary outcome was the CPR quality (compression rate, compression depth, incomplete compressions). Data are presented as mean ± standard deviation. Results: In the observation period the compression rate was 99.8 ± 13.5 compressions/min, compression depth was 48.8 ± 11.5 mm and the decompressions were incomplete in 40 ± 38% of all compressions. Time needed to apply the electrodes was 52 ± 10 s and 92% of the participants applied them correctly. The time until first shock delivery was 71 ± 10 s. The hands-off-ratio was 16 ± 7%. Conclusion: In a highly motivated but untrained group such as medical students, CPR-quality needs substantial improvement. While the application of an AED was acceptable, the quality of chest compressions was too low. These results highlight the importance of further improved structured training throughout the medical curriculum. The progress of CPR-quality will be evaluated before every CPR-course and reported in future studies.

Purpose of the study: A new automated extern defibrillator (AED) features an integrated video screen with conventional voice prompts and additional video animation for Basic Life Support (BLS). The aim of the study was to compare CPR-quality using AEDs with and without video instruction during BLS provided by firstyear medical students without prior AED training. Materials and methods: This open, prospective, controlled trial randomized 336 medical students in their first weeks at the Medical University of Vienna, into two groups: audio only, or audio plus video AED during CPR. Each student performed 4 minutes of single rescuer chest compression BLS on a manikin (Ambu Man C, Ballerup, Denmark). Effective compression ratio (ECR), and the subjective CPR-quality was assessed in each group. The ECR is defined as effective compression ratio (compressions with correct depth, correct hand position and complete decompression) multiplied by flow time (active CPR time). In this setting, correctly performed compression-only CPR has a maximum ECR of 0.92. The subjectively self-assessed CPR-quality was rated on a 10-point Likert scale (lowest = 0 to highest = 10) by the participants. Data are presented as mean ± SD. A p < 0.05 was considered as significant. Results: No difference was found between the two groups in the objective measures of ECR (audio–video 0.1 ± 0.2 vs., audio only 0.1 ± 0.2, p = 0.682). The subjective CPR-quality rating was significantly better for the audio–video AED users (6.8 ± 1.7) compared to audio only (6.2 ± 1.9) (p = 0.002). Conclusion: CPR-quality with the help of a new AED with audio/video animation was similarly poor compared to the use of a standard AED. Further development should concentrate on the influence of the video content and if that can improve performance in different specific populations.
