Adrenal epinephrine increases alveolar liquid clearance in a canine model of neurogenic pulmonary edema.

Case reports of neurogenic pulmonary edema (NPE) often indicate that the edema resolves quickly. Because plasma epinephrine concentration may be elevated in NPE, and epinephrine has been shown to increase the rate of alveolar liquid clearance (ALC),…

Effect of elevated vascular pressure transients on protein permeability in the lung.

Neurogenic pulmonary edema (NPE) may develop in individuals with head trauma or seizures and is generally thought to have a hydrostatic basis in the severe degree of pulmonary hypertension that occurs. Recently, it has been suggested that vascular…

Pulmonary vasoconstriction in a canine model of neurogenic pulmonary edema.

The intracisternal administration of veratrine to the chloralose-anesthetized dog produces pulmonary hypertension (PH) and neurogenic pulmonary edema (NPE). To determine whether pulmonary vasoconstriction, mediated by a circulating agent, contributes…

Dose-response relationship between plasma epinephrine concentration and alveolar liquid clearance in dogs.

Previously, alveolar liquid clearance (ALC) was observed to increase in a canine model of neurogenic pulmonary edema (NPE) by adrenal epinephrine (S. M. Lane, K. C. Maender, N. E. Awender, and M. B. Maron. Am. J. Respir. Crit. Care Med. 158:

Effect of high transcapillary pressures on capillary ultrastructure and permeability coefficients in dog lung.

Edema development and recovery in neurogenic pulmonary edema.

Time course of blood volume changes in an isolated lung lobe after venous pressure elevation.

The elevation of venous pressure (Pv) in isolated perfused organs causes organ weight to increase in a biphasic manner. The initial rapid phase results primarily from an increase in blood volume (BV), whereas the second slower phase is generally…
