Factors influencing quality of chest compression depth in nursing students

The purpose of the study was to identify factors influencing quality of chest compression depth in nursing students. A convenience sample of 102 female nursing students enrolled in a cardiopulmonary resuscitation skills training session. Each student performed 3 min of chest compression skills on a Resusci Anne SkillReporter manikin for measurements of both depth and rate. Nursing students with correct compression depth (50–60 mm) had higher body weight (t = ?2.02, P = 0.046) and body mass index (t = ?2.19, P = 0.031) compared with students in the incorrect depth group. Mean chest compression depth was shallower in underweight nursing students compared with normal weight or overweight students (F = 8.89, P < 0.001). Body weight was a significant factor influencing quality of chest compression depth (F = 4.25, P = 0.003). Educational intervention targeting underweight nursing students might need to enhance the quality of chest compression skills.
