Neurogenic pulmonary edema
Neurogenic pulmonary edema is described in diseasesCNS in persons without previous violations of the function of the left ventricle. It has been experimentally proved that the rise in sympathetic tone plays an important role in the onset of pulmonary edema, however, exact mechanisms have not been elucidated. It is known that the stimulation of sympathetic nerves causes a spasm of arterioles. increased blood pressure and centralization of hemodynamics; in addition, a decrease in left ventricular compliance is possible. All this leads to increased pressure in the left atrium and pulmonary edema, which is based on hemodynamic disorders. There is experimental evidence that stimulation of adrenoreceptors directly increases the permeability of capillaries, but this effect is less important than the imbalance between hydrostatic and oncotic pressure.
