Figure 1 Ventilations. (A) Time to first ventilation. Each dot represents a participant’s time to first ventilation. Data are median time to first ventilation with first and third quartile. Data on one surf lifeguard are missing. (B) Tidal volume. Each dot represents a participant’s mean tidal volume. Data are mean tidal volume with standard deviations. The gray area marks the recommended tidal volume by the ERC (0.5–0.6 L).
