Figure 1From: Impact of physical fitness and biometric data on the quality of external chest compression: a randomised, crossover trial Force-depth relationship of the manikin used in this study. Dashed arrows indicate the corresponding force for the minimal recommended chest compression depth of 38 mm (2005 Guidelines), and 50 mm (2010 Guidelines), respectively. The star indicates the threshold used by Fried et al. to define leaning on the patient's chest [20].Back to article page
