Two-Thumb Technique Is Superior to Two-Finger Technique in Cardiopulmonary Resuscitation of Simulated Out-of-Hospital Cardiac Arrest in Infants.

Background To compare the 2-finger and 2-thumb chest compression techniques on infant manikins in an out-of-hospital setting regarding efficiency of compressions, ventilation, and rescuer pain and fatigue. Methods and Results In a randomized crossover design, 78 medical students performed 2 minutes of cardiopulmonary resuscitation with mouth-to-nose ventilation at a 30:2 rate on a Resusci Baby QCPR infant manikin (Laerdal, Stavanger, Norway), using a barrier device and the 2-finger and 2-thumb compression techniques. Frequency and depth of chest compressions, proper hand position, complete chest recoil at each compression, hands-off time, tidal volume, and number of ventilations were evaluated through manikin-embedded SkillReporting software.
