Compression depth and rate. Part a: The mean compression depth (mm) performed by the ambulance personnel (N = 20). The recommended compression depth in guidelines 2005 for resuscitation was 40–50 mm and 55% achieved this. Part b: The mean compression rate (compressions/min) performed by the ambulance personnel (N = 20). The optimal compression rate according to guidelines 2005 for resuscitation was 100/min.
