Development of lung edema: interstitial fluid dynamics and molecular structure
Abstract
Pulmonary interstitium is maintained dehydrated at subatmospheric pressure (-10 cmH(2)O) through low capillary permeability, low tissue compliance, and an efficient lymphatic drainage. Enzymatic degradation of proteoglycans disrupts the endothelial basal membrane and the matrix structure, triggering the development of pulmonary edema.
