Effectiveness of body position modifications during simulated CPR on chest compression quality in patients with obesity.

A total of 60 paramedics will be included in this study. All participants will perform 2-minute chest compression (CPR) sessions on manikins simulating patients with and without obesity. Interventions involve modified body positioning to optimise compression mechanics. Each paramedic will perform compressions in both standard and modified positions in a randomized crossover design. CPR quality parameters (compression depth, rate, and full chest recoil) are measured using the Laerdal QCPR Meter 2. 1. Paramedics will perform CPR in the following three randomized conditions: - Standard CPR on a manikin with normal body mass, placed on the floor - CPR on an obese manikin placed on the floor - CPR on an obese manikin placed on the floor, using a 10 cm knee pad to assist ergonomic positioning All compressions are performed without real-time feedback. A 3-minute rest is provided between sessions. Each participant will also complete a pre-test demographic questionnaire (age, sex, BMI, profession, CPR experience, etc.). All procedures are conducted at the Medical Simulation Centre and EMS training facilities under standardised supervision.
