  1. Values recorded before sacrifice of animals with sham injury (control) and at different time points after induction of sepsis following acute lung injury. Each group includes four animals.
  2. MPAP, mean pulmonary arterial pressure; PCWP, pulmonary capillary wedge pressure; Ppeak, peak airway pressure; Ppause, pause airway pressure; PVR, pulmonary vascular resistance. a P < 0.05, b P < 0.01.
