The current situation of pulmonary surfactant replacement therapy pulmonary surfactant adsorbed on the alveolar gas / liquid interface, reducing its surface tension, which has the stability of the alveolar pressure and prevent pulmonary edema role. In response to neonatal respiratory distress syndrome caused by the lack of the substance, the use of respiratory surfactant surgically-supplemented therapy effectively improves the rescue rate. As adult respiratory distress syndrome (...
