“…(11,(16)(17)(18) In fact, a study by Szpilman and Soares (17) concluded that performing in-water ventilations increases the chances of survival of the victim; and later, in a pilot evaluation, Perkins (16) demonstrated the possibility of proper ventilation in the water, with flotation material, and previous training. Despite the scientific evidence supporting the importance of ventilations, some studies reported that lifeguards perform ventilations poorly, (10,19) pointing to a potential gap in the training programs that needs further investigation. In the present study, the rescuers were told not to perform in-water ventilations to avoid the decrease of intensity in the rescue.…”
