Evaluation of lung function measurement assessed by constant phase model obtained in mice using orotracheal intubation and tracheostomy, both using the intubation cannula. a, b, Average real (top) and imaginary (bottom) parts of respiratory system input impedance (Zrs) obtained in intubated (“OTI”, in blue) mice and tracheostomized (“TRA”, in red) mice. n = 8 BALB/cJ mice (a), n = 15 C57BL/6 J mice (b). Lower and upper error bars represent standard deviations respectively for intubation and tracheostomy. c-i, newtonian resistance (“Rn”, c and e), tissue damping (“G”, d, f), tissue elastance (“H”, g, i) in intubated and tracheostomized BALB/cJ mice (c, d, g) and C57BL/6 J mice (e, f, i). Data represent individual mice and are analyzed by the Wilcoxon signed-rank test or paired t tests. * P < 0.05
