HTS produces massive movement of water out of edematous swollen cells and into the blood vessels. This movement of water out of the brain can reduce swelling and improve cerebral blood flow. This specific action of HTS is due to its reflection coefficient of 1. The high numbers of particles in the solution pull water from a low-pressure compartment to a higher-pressure one. Compared with another osmotic diuretic such as mannitol, in which the reflection coefficient is (allowing some leakage outside the blood vessels), HTS will not leak outside the capillaries in the presence of an intact blood-brain barrier.
Q. what is "pulmonary edema" and what are the risks? my Dr. told me I'm in a risk group for pulmonary edema, he tried to explain what it is but i didn't understand fully...if someone may give me a brief explanation- I'll appreciate it! A. pulmonary edema occurs when, lets say, your heart left ventricle stops working properly and your right ventricle works fine. that means your lungs getting lets presume- 1 liter of blood -but your left ventricle can pump out of it only 990 ml. that means you have high blood pressure in your lungs and fluid comes out of blood vessels and fills your lungs, making it harder and harder breathing.
