From: Aerosolised surfactant generated by a novel noninvasive apparatus reduced acute lung injury in rats
PPS administration improved recovery of PaO2 and decreased respiratory rates after acute lung injury was induced with oleic acid. (a) Arterial partial pressure of oxygen (PaO2) in instillation groups. (b) PaO2 in aerosolisation groups. (c) Respiratory rates in instillation groups. (d) Respiratory rates in aerosolisation groups. Mean ± standard deviation with different number of animals per group: model and saline-inst groups (n = 7), PPS-inst group (n = 10), saline-aer group (n = 13) and PPS-aer group (n = 16). * P < 0.05 compared with the model group. B = baseline; M = model, 30 minutes after oleic acid injection and the beginning of treatments; PPS = porcine pulmonary surfactant.
