From: Repeated endo-tracheal tube disconnection generates pulmonary edema in a model of volume overload: an experimental study

Fig. 3

Respiratory, hemodynamic and gas exchange variables during ETT disconnect (series III): Normal Pigs (n = 6), after receiving volume overload were randomized to either repeated ETT disconnection every 15 min, lasting 15 s each (Disconnect group) or no disconnections (Control group), for 3 h. Repeated disconnection led to higher driving (A) and mean PA pressures (C), as well as lower respiratory system compliance (B) and oxygenation (D). # P < 0.05; post-hoc t-test; disconnect versus control. Abbreviations: ETT endo-tracheal tube, CRS compliance of the respiratory system, PaO2 partial pressure of arterial oxygen, PA pressure pulmonary artery pressure
