The effect of a dynamic overlay mattress on chest compression quality during cardiopulmonary resuscitation

INTERVENTION: In this manikin‐based simulation study, participants (students from two nursing education programs) are going to be allocated to one arm of the two‐arm parallel‐group design using block randomisation. The students will be blinded to the allocation. Student body height (in cm), body weight (in kg) will be collected. The students will be assessed for the quality of chest compressions during adult cardiopulmonary resuscitation (CPR), in a 2‐minutes cardiac arrest CPR scenario, on either: 1. A manikin in bed on a memory foam mattress (control group) 2. A manikin in bed on a dynamic overlay mattress on top of a memory foam mattress (intervention group) CONDITION: Chest compression quality in patients who had a cardiac arrest ; Circulatory System ; Cardiac arrest PRIMARY OUTCOME: ; 1. Chest compression rate is measured in the total number of compressions per min using a feedback device; 2. Sternum‐to‐spine chest compression depth is measured in mm using a feedback device; 3. Hand positioning is measured in scores out of 100 using a feedback device; SECONDARY OUTCOME: 1. The predictive effect of body height (cm), body weight (kg), hand positioning (scores out of 100), and mattress type (dynamic overlay mattress or not) on depth and frequency of chest compressions measured using a feedback device INCLUSION CRITERIA: 1. Enrolled as a student in one of the two selected nursing education programs 2. Aged =18 years 3. Successfully completed a basic CPR training 4. Successfully completed first year of nursing education
