case_images: The mean duration of bystander CPR was 6.5 minutes (ranging from 1 to 26 minutes) with 10 cases (38.5%) over 7 minutes and 3 (11.5%) over 10 minutes [Figure 2]. In the remaining case, we found chest pain upon inspiration, indicating a minor rib fracture or muscular damage; this was easily controlled with analgesics [Figure 2].
