Figure 2From: Comparison of the quality of chest compressions on a dressed versus an undressed manikin: A controlled, randomised, cross-over simulation studyAverage maximum compression depth (mm) for laypeople (left) and firefighters (right) when providing chest compressions on a manikin with an undressed versus a dressed chest (present guidelines and intervention, respectively). The grey area indicates the recommended compression depth (ranging from 40-50 mm).Back to article page
