Chapter 1, Problem 22RA
Summary Introduction
To review:
The effect on rate and strength of a person due to rapid drop in blood pressure.
Introduction:
Hypotension or low blood pressure is the lowering of blood pressure to such a level that it results in an inadequate flow of blood to the organs of the body. The cause of a sudden drop in blood pressure can be dehydration, changing body position suddenly, and severe loss of blood. Low blood pressure results in fainting, dizziness, and lightheadedness.
