Out-of-hospital cardiac arrest (OHCA) remains one of the leading causes of sudden death, especially in environments with limited cardio-safe infrastructure. This research corresponds to an experimental phase focused on the biomechanical analysis of the CPR maneuver, guided by the depth, frequency, and decompression recommendations from ILCOR and AHA. The data obtained will help establish the mechanical parameters that the automated prototype must meet to ensure efficient CPR in later stages of development. The experimental validation was carried out using professional simulation mannequins, force instrumentation, three-dimensional motion capture, and an analysis of the CPR technique by emergency medical technicians. An average compression depth of 5.38 cm, an average rate of 110 compressions per minute, and an average peak force of 250.59 N were recorded, in accordance with international guidelines. The results show how the CPR maneuver loses efficiency over time, both in force and displacement data. Therefore, this work represents a significant contribution to the field of bioengineering applied to prehospital care, with a potential impact on the creation of cardio-protected environments and the improvement of survival rates in cardiovascular emergencies.
