Fig. 3From: Devising negative pressure within intercuff space reduces microaspirationVolume of fluid leaked at different cuff pressures and negative suction pressures for 10 min. The data show a strong inverse relationship between negative pressure and leakage volume. *P < 0.05 vs control. At all negative pressures, the leaked volume from the new tracheal tube were significantly less compared to that of the controlBack to article page
