Gerber L, Botha M, Laher AE, et al. - During cardiopulmonary resuscitation (CPR), bag-valve-mask (BVM) ventilation using a two-handed mask–face seal, vs a one-handed mask–face seal, has been described as superior. In this study, comparison was performed between CPR quality metrics during simulation-based two-rescuer CPR with a modified two-handed mask–face seal technique and two-rescuer CPR with the conventional one-handed mask–face seal technique. Two-rescuer CPR was performed by participants on a simulation manakin and alternation was done between the modified and conventional CPR methods. Observations suggest that with minor modifications to the conventional method of simulated two-rescuer CPR, significantly higher volumes of rescue breaths can be delivered by rescuers without compromising the quality of chest compressions.
