Fig. 2From: Comparison of the effects of using feedback devices for training or simulated cardiopulmonary arrestEffects of the AVF device used in training and simulated CA on CC Quality. (A) The mean proportion of CCs with appropriate depth between 5 and 6 cm. (B) The mean proportion of CCs with a rate of 100–120 per minute. AVF: audiovisual feedback. CA: simulated cardiopulmonary arrest. CC: chest compressionBack to article page
