Infant CPR guidelines recommend two-finger chest compressions with a lone rescuer and two-thumb with two rescuers. Two-thumb provides better chest compression but is perceived to be associated with increased ventilation hands-off time. A manikin study revealed more effective compressions with the two-thumb technique with only four fewer compressions per minute compared with two-fingers.
