Figure 4. This histogram shows time to intubation (+/- SD) during each laryngoscopy sequence. The times to intubation are similar when comparing the Bullard without ILS and the Macintosh laryngoscope with ILS. The fastest method of intubation is the Macintosh laryngoscope without ILS and the greatest time to intubation was required when using the Bullard laryngoscope with ILS.
