Cioccari G, et al. - The 2‐finger and 2‐thumb chest compression techniques were compared on infant manikins in an out‐of‐hospital setting with regard to their efficiency of compressions, ventilation, and rescuer pain and fatigue.

• In a randomized crossover design, 2 minutes of cardiopulmonary resuscitation with mouth‐to‐nose ventilation were performed by 78 medical students on a Resusci Baby QCPR infant manikin (Laerdal, Stavanger, Norway) at a 30:2 rate, using a barrier device and the 2‐finger and 2‐thumb compression techniques.

• Manikin‐embedded SkillReporting software was used to evaluate the frequency and depth of chest compressions, proper hand position, complete chest recoil at each compression, hands‐off time, tidal volume, and number of ventilations.

• A total of 156 complete interventions were performed by the students.

• A greater depth of chest compressions (42 vs 39.7 mm), and a higher percentage of chest compressions with adequate depth (89.5% vs 77%) were recorded in correlation with applying the 2‐thumb technique.

• Overall, the 2‐thumb technique resulted in better quality of chest compressions without interfering with ventilation and caused less rescuer pain and fatigue.
