Experiment Objectives
- To become familiar with the principle of plethysmography and its usefulness in qualitatively assessing peripheral changes in blood volume.
- To observe and record changes in peripheral blood volume and pressure pulse under a variety of both experimental and physiological conditions.
- To determine the approximate speed of the pressure pulse wave traveling between the heart and the finger.
- To illustrate the electrical activity associated with normal cardiac activity and how it relates to the flow of blood
throughout the body.
