Intensity Modulated Radiation Therapy (IMRT) is a computer-based. method of planning for, and delivery of generally narrow, patient specific, spatially and often temporally modulated beams of radiation to solid. tumors within a patient.
So, ingesting large amounts of salt results in a high sodium concentration in the blood stream. This in turn causes water to enter the blood vessels by osmosis. More water in the blood means a greater volume of liquid and, therefore, higher blood pressure. With low salt concentrations, water exits the loop and is retained by the body. When sodium concentration is high, the opposite occurs, water enters the blood stream by osmosis and increases blood pressure.
Illness and Heart Rate. Infections and dehydration can cause your heart rate to go up, says Medline. Indeed, dehydration leads to blood volume, and therefore blood pressure, reductions. The pressure receptors in your arteries are so sensitive that even small changes can trigger a response from your brain stem.
