ObjectivesCurrent European guidelines for pediatric cardiopulmonary resuscitation (CPR) recommend the lower half of the sternum as the chest compression point (CP). In this study, we have used thoracic CT scans to evaluate recommended and optimal CP in relation to cardiac anatomy and structure.DesignAnalysis of routinely acquired thoracic CT scans acquired from 2000 to 2020.SettingSingle-center pediatric department in a German University Hospital.PatientsImaging data were obtained from 290 patients of 3-16 years old.InterventionsNone.Measurements And Main ResultsWe measured and analyzed 14 thoracic metrics in each thoracic CT scan. In 44 of 290 (15.2%) scans, the recommended CP did not match the level of the cardiac ventricles. Anatomically, the optimal CP was one rib or one vertebral body lower than the recommended CP, that is, the optimal CP was more caudal to the level of the body of the sternum in 67 of 290 (23.1%) scans. The recommended compression depth appeared reasonable in children younger than 12 years old. At 12 years old or older, the maximum compression depth of 6 cm is less than or equal to one-third of the thoracic depth.ConclusionsIn this study of thoracic CT scans in children 3-16 years old, we have found that optimal CP for CPR appears to be more caudal than the recommended CP. Therefore, it seems reasonable to prefer to use the lower part of the sternum for CPR chest compressions. At 12 years old or older, a compression depth similar to that used in adults-6 cm limit-may be chosen.Copyright © 2024 The Author(s).
