Summary
Objective: The effects of the recommended 30:2 compression:ventilation (C:V) ratio on chest
compression rate (CR), compression depth (CD), compression pressure (CP) and rescuer fatigue
is unknown during pediatric CPR. We hypothesized that a 30:2 C:V ratio will decrease com-
pression depth and compression pressure and increase rescuer fatigue compared with a 15:2
ratio.
Design: Randomized crossover observational study.
Methods: Adolescent, child and infant manikins were modified to digitally record compression
rate, compression depth, compression pressure and total compression cycles (CC). BLS or PALS
certified volunteers were randomized to five CPR groups: adolescent (AD), child 1-hand (OH),
child 2-hand (TH), infant two-finger (TF) and infant two-thumb (TT). Each rescuer performed
each ratio for 5 min with the order randomized. Rescuer heart rate (HR) and respiratory rate
(RR) were recorded continuously during CPR and used to determine the recovery time (RT)
for HR/RR to return to baseline. Data (mean ± S.D.) were contrasted by paired differences for
quantitative data and the sign rank test for ordinal data.
