Figure 3From: Susceptibility to ventilator induced lung injury is increased in senescent ratsMean airway pressures (Paw) in young (black circles) versus old (white circles) mechanically ventilated rats. Mechanical ventilation (MV) was applied with tidal volume (VT) of 8, 16 or 24 ml/kg body weight, respectively. * = P <0.05 old vs. young animals; #, § = P <0.05 time point vs. start of MV.Back to article page
