We explored the potential for over-compression from current paediatric chest compression depth guidelines using computed tomography(CT) images of a large, heterogenous, Asian population.A retrospective review consecutive children, less than 18-years old, with CT performed between 2005 to 2017 was done. Demographic data were extracted electronic medical records. Measurements internal and external anterior-posterior diameters (APD) taken at lower half sternum. Simulated compressions evaluate proportion population residual cavity dimensions 0 mm (RICD < mm, representing definite over-compression; exceeding APD), RICD 10 over-compression).592 studies included study. one-third APD had least no infants 0.3% children mm). 4 cm simulated led 18% (95% CI 13%-24%) over-compression, this increased 34% 27%-41%) 4.4 (upper limit "approximately" cm; + 10%). 5 resulted in 8% 4%-12%) 1 8-years-old 22% 16%-28%) 5.5 cm, 10%).In settings whereby depths can be accurately measured, recommended approximately (in infants) young children) could result over-compression.
