Effects of alternating hands during in-hospital one-handed chest compression: A randomised cross-over manikin trial.

Objective: We evaluated the decrease in chest compression depth during continuous one-handed chest compression (OHCC) in an in-hospital paediatric arrest setting, and whether switching hands could delay the decrease in chest compression depth.

Methods: In total, 30 healthcare providers were randomised into groups A and B. Group A performed test 1 (chest compressors alternated hands every 30 s in 2 min of OHCC), followed by test 2 (chest compressors used one hand for 2 min without switching to the other hand) and group B, vice versa.
