Efficacy of the ETT cleaning system. a The volume of ETT secretions increases in the control group (black columns) from the ventilator to the tip side (secretions analyzed dividing the studied ETT length in three equal parts), while it is lower (p < 0.001 by ANOVA) and fairly constant in the treatment group (white columns). b ETT cross-sectional area reduction measured every 5 mm among treatments (white circles) and controls (black circles). The maximum cross-sectional area reduction is markedly lower in the treatment group (dashed lines, p = 0.003). *p < 0.05 as compared to controls
