Hemodynamic stability literally means "stable blood flow." According to the Hemodynamic Society, hemodynamics describe the forces in which the heart pumps blood through the cardiovascular system. If one has stable hemodynamics, it means that the force in which the heart pumps blood is stable. Stable blood flow provides a steady supply of oxygen to all tissues, explains the Hemodynamic Society.
Hemodynamic stability means that a person has a stable blood pressure and consistent flow of blood through his body. Hemodynamics is a term used to describe the intravascular pressure and flow that is produced by the heart's contractions. When the heart contracts, it pumps blood throughout the body: The blood circulates in a closed circuit. Inconsistent pressure and blood flow variations can damage the heart and threaten a person's cardiovascular health.
According to Wikipedia, all animal cells require oxygen in order for organs and muscles to function properly. The circulatory system's main function is to transport the blood, delivering oxygen, nutrients, and other bodily chemicals to cells throughout the body. The circulatory system also removes cellular waste.
This process is dependent on one's heart as it pumps the blood. For example, when a person is exercising or playing a sport, the heart is pumping much faster: This increase in pressure and blood flow creates an unstable hemodynamic condition. Prolonged activity that overworks the heart can cause damage to the muscle and result in hemodynamic dysfunction.
