Hemodynamic disorders

Home > Medicine > Pathology > Hemodynamic disorders

Covers the disturbances in blood flow due to various causes like obstruction, decreased blood volume, and increased blood pressure. Explains the consequences of these disorders on different organs and tissues.

Blood flow dynamics: Understanding the principles of blood flow in the circulatory system and the forces that affect it.
Arterial hypertension: A condition where blood pressure in the arteries is consistently elevated, causing damage to blood vessels and organs.
Atherosclerosis: A disease in which plaques build up inside arteries, causing them to narrow and restricting blood flow.
Congestive heart failure: A condition in which the heart is unable to pump enough blood to meet the body's demands, leading to fluid buildup in the lungs and other organs.
Cardiogenic shock: A life-threatening condition that occurs when the heart is unable to pump enough blood to maintain vital organ functions.
Pulmonary hypertension: A condition in which blood pressure in the lungs' vessels is elevated, leading to shortness of breath and fatigue.
Thrombosis and embolism: The formation of blood clots, which can travel to other parts of the body and cause serious damage.
Vasoconstriction and vasodilation: The constriction and dilation of blood vessels, which affect blood flow and blood pressure.
Endocarditis: A bacterial infection of the inner lining of the heart, leading to inflammation and damage to heart valves.
Anemia: A condition in which the body lacks enough healthy red blood cells to carry oxygen to tissues, leading to fatigue and other symptoms.
Shock: A medical emergency in which blood pressure drops dramatically, causing organ failure and potentially death.
Hypotension: A condition in which blood pressure is consistently low, leading to decreased blood flow to vital organs.
Hemorrhage: A significant loss of blood, which can cause hypovolemia (low blood volume) and hypotension.
Myocardial infarction: A heart attack, which occurs when blood flow to a part of the heart is blocked, leading to damage to heart muscle.
Arrhythmias: Disorders of the heart's electrical system, leading to irregular heartbeats and potential failure.
Valvular heart disease: A condition in which one or more heart valves are damaged, leading to problems with blood flow through the heart.
Cardiac tamponade: A condition in which fluid accumulates in the sac surrounding the heart, leading to decreased heart function.
Aortic aneurysm: A bulge in the wall of the aorta, which can rupture and cause life-threatening bleeding.
Microvasculature disorders: Diseases affecting the small blood vessels, causing decreased blood flow to organs and tissues.
Vasculitis: Inflammation of the blood vessels, leading to damage and resistance to blood flow.
Hypertension: It is a condition where the blood pressure in arteries is constantly elevated above the normal levels for a prolonged time.
Hypotension: It is a condition characterized by a blood pressure lower than normal levels, which could lead to impaired blood supply to the organs.
Shock: Shock occurs when insufficient oxygenated blood reaches the tissues, which could lead to organ failure.
Atherosclerosis: It is a pathological condition where the walls of the arteries become thickened due to the buildup of plaques, causing a reduction in blood flow, and further narrowing of the vessel lumen.
Arteriosclerosis: It is a pathological condition where the arterial walls become hardened and thickened, leading to reduced blood flow, which could further result in different heart diseases.
Thrombosis: It is a pathological condition where a blood clot forms inside a blood vessel, which could obstruct the blood flow and cause severe damage to the affected tissue.
Embolism: It is a condition where a clot, air bubble, or any other foreign material travels through the bloodstream and blocks the blood flow in narrower vessels, leading to obstruction of flow and damage to body organs.
Hemorrhage: It is a pathological condition where excessive bleeding occurs internally or externally, which could lead to a significant decrease in blood volume resulting in a life-threatening situation.
Congestive heart failure: It is a medical condition in which the heart functions abnormally, leading to inadequate delivery of oxygenated blood to the rest of the body.
Valvular heart diseases: These affect the heart valves, and might cause them to become stenotic or incompetent, thereby leading to a decrease in cardiac output and pulmonary circulation.
"Hemodynamics or haemodynamics are the dynamics of blood flow."
"The circulatory system is controlled by homeostatic mechanisms of autoregulation."
"The hemodynamic response continuously monitors and adjusts to conditions in the body and its environment."
"Hemodynamics explains the physical laws that govern the flow of blood in the blood vessels."
"Blood flow ensures the transportation of nutrients, hormones, metabolic waste products, oxygen, and carbon dioxide throughout the body."
"Maintain cell-level metabolism, regulate the pH, osmotic pressure and temperature of the whole body, and protect from microbial and mechanical harm."
"Blood is a non-Newtonian fluid."
"Blood flow is most efficiently studied using rheology rather than hydrodynamics."
"Classic hydrodynamics and fluids mechanics based on the use of classical viscometers are not capable of explaining haemodynamics."
"The study of blood flow is called hemodynamics."
"The study of the properties of blood flow is called hemorheology."

"Blood is a non-Newtonian fluid."
"Rheology is the approach used to study blood flow."
"Classic viscometers are not capable of explaining haemodynamics due to blood vessels not being rigid tubes."
"Understanding hemodynamics is crucial for understanding the properties of blood flow."
"The study of blood flow, called hemodynamics, is closely related to the study of its properties known as hemorheology."
