Comparison of Direct and Indirect Laryngoscopes in Vomitus and Hematemesis Settings: A Randomized Simulation Trial

Figure 2

Box-and-whisker plot (median, IQR, and range) of time required for simulated tracheal intubation in hematemesis and vomitus settings using each laryngoscope. Results are expressed as means ± SDs and were analyzed using one-way analysis of variance. (a) Normal setting, (b) hematemesis, and (c) vomitus setting.
