Table 2 ‘Time to tracheal ventilation’ in seconds using the tracheal tube

From: The novel intubating laryngeal tube (iLTS-D) is comparable to the intubating laryngeal mask (Fastrach) – a prospective randomised manikin study

  1. Time points: consecutive trials 1, 2, 3, 4; median, minimum, maximum, upper and lower quartile of ‘time to ventilation’ for the particular instrument displayed as boxplot; after trials 1, 2, and 3, there was no difference in ‘time to ventilation’ for the tracheal tube inserted through the Fastrach and the iLTS-D in trial 4 (Fastrach: median: 14.0 s., iLTS-D: 14.0 s., p = 0.16)
