WebHMD occurs when there is not enough of a substance in the lungs called surfactant. Surfactant is made by the cells in the airways and consists of phospholipids and protein. It begins to be produced in the fetus at about 24 to 28 weeks of pregnancy, and is found in amniotic fluid between 28 and 32 weeks. WebThe traditional functions of surfactant are biophysical activities to keep the lungs open, to decrease the work of breathing, and to prevent alveolar edema. Most of the components … WebThe administration of exogenous surfactant either via a bronchoscope or nebulizer may reduce surface tension within alveoli and prevent cyclical collapse, improving oxygenation, and ameliorating VILI. Multiple administrations appear necessary due to the neutralization of surfactant by edema fluid. mapa de guatemala si nombres
