Introduction: Basic life support represents a crucial intervention in cardiac arrest, in which high-quality chest compressions significantly affect survival. Guidelines recommend performing compressions on a firm and flat surface; however, cardiac arrest can also occur on more demanding terrain, such as a slope. In the available literature, we did not find studies addressing the influence of rescuer position on the quality of chest compressions performed on a slope. Purpose: The aim of the diploma thesis was to determine the influence of rescuer position on the quality of chest compressions performed on a slope and to define the most favourable position based on measured parameters and the performers’ subjective evaluations. Methods: An experimental study was conducted in a simulated environment on a sample of 50 participants. Each participant performed chest compressions in three positions relative to the casualty: uphill, downhill, and parallel. Compression quality parameters were measured using the Laerdal QCPR application, while subjective evaluations were collected using a questionnaire in which participants rated individual aspects (e.g., difficulty, stability, pain, fear of falling) on a Likert scale. Data were analysed using non-parametric tests (Friedman test and Wilcoxon test). Results: It was found that rescuer position statistically significantly (p < 0.05) influences the quality of chest compressions and subjective evaluations. The downhill position achieved the highest overall performance (median 99%) and the greatest proportion of appropriate compression rate (90%), whereas in the uphill position the rate was the highest (122 compressions/min) and exceeded recommended values. In subjective evaluations, the uphill position was rated as the least favourable, with higher physical demand (median 4), lower stability (median 4), and greater fear of falling (median 3), whereas ratings in the downhill position were lower (medians between 1 and 3). Discussion and Conclusion: The results indicate that rescuer position significantly influences the quality of chest compressions, as well as the performer’s sense of safety and physical strain. The downhill position proved to be the most favourable, while the uphill position was less suitable in several parameters. The findings have important practical value for performing resuscitation on challenging terrain and provide a basis for further research.
