Hemodynamics is concerned with the mechanical and physiologic properties controlling blood pressure and flow through the body. a full discussion of hemo dynamic principles is beyond the scope of this book. in this chapter, we present an overview of basic principles that are helpful in understanding hemodynamics. 1. Understanding pressure and pressure volume concepts helps to contextualize the hemodynamic assessment, since hemodynamics measure pressure and flow but fail to capture volume. the pressure volume loop of the left ventricle (lv) operates within the space subtended by the end systolic pressure volume relationship (espvr; also known as end. Hemodynamics (pressure, flow, and resistance) hemodynamics can be defined as the physical factors that govern blood flow. these are the same physical factors that govern the flow of any fluid, and are based on a fundamental law of physics, namely ohm's law, which states that current (i) equals the voltage difference (Δv) divided by resistance (r).

The normal venous system is a low pressure, large volume reservoir of blood which enables cardiac output to increase rapidly. the pressure and velocity of a fluid in a closed system are related. the velocity of blood increases and pressure decreases as cross sectional area of the blood vessel decreases. Each phase of the cardiac cycle results in electrical activity, pressure changes, and volume adjustments that account for maintaining cardiac output, and therefore tissue perfusion throughout the body. in the following chapter, the cardiac cycle is discussed as well as normal hemodynamic physiology. download chapter pdf.
