Perfusionist A perfusionist, also known as a clinical perfusionist or a cardiovascular perfusionist, is a specialized healthcare professional who uses the heart-lung machine during cardiac surgery and other surgeries that require cardiopulmonary bypass to manage the patient's physiological status.he perfusionist is responsible for the management of circulatory and respiratory functions of the patient which has a great effect on the patient systemic condition and allows the cardiac surgeon to focus on the actual surgical procedure and less on the immediate needs of the patient.

Mayo Clinic School of Health Sciences In addition, new procedures for many types of heart disease, defects and disorders are increasing the need for cardiovascular perfusion services. Employment of perfusionists is expected to grow faster than the average for all occupations as the volume of cardiac surgery increases.

What is aerobic (cardiovascular) fitness? Cardiovascular fitness is measured as the amount of oxygen transported in the blood and pumped by the heart to the working muscles and as the efficiency of the muscles to use that oxygen.

- A stress myocardial perfusion scan is used to assess the blood flow to the heart muscle (myocardium) when it is stressed by exercise or medication and to determine what areas of the myocardium have decreased blood flow.

What is Perfusion? In the process of perfusion, blood moves its way out from the heart, through a network of arteries, and into the smallest blood vessels in the body, the capillaries. As the blood flows through the capillaries, it brings vital nutrients to the tissues of the body, and helps to sweep away waste.

CARDIOVASCULAR REGULATION CARDIOVASCULAR REGULATION. . .  . Homeostatic mechanisms regulate cardiovascular ac­tivity to ensure that tissue perfusion, or blood flow through tissues, meets the demand for oxygen and nu­trients. The three variable factors are: (1) Cardiac out­put, (2) peripheral resistance, and (3) blood pressure. n n. Factors involved in the regulation of cardiovascular function include local factors, neural mechanisms, and endocrine mechanisms. . A. Local factors: Local factors change the pattern of blood flow within capillary beds in response to chemical changes in interstitial fluids.

- Ventilation perfusion ratio is an indicator of how well the oxygen  we breathe in is being transported through the lungs and into the  blood system.hile blood … flow is generally understood as an increase in the total amount of blood flowing into an anatomic structure or region, tissue perfusion is the amount of blood that actually flow through the capillaries of the vascular bed of that structure or region.

perfusion 1. the act of pouring through or over; especially the passage of a fluid through the vessels of a specific organ. 2. a liquid poured through or over an organ or tissue. perfusion pressure. the gradient between arterial blood pressure and venous pressure in a comparable location in the vascular tree.

Pulmonary circulation Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart.The term pulmonary circulation is readily paired and contrasted with the systemic circulation.he pulmonary arteries carry deoxygenated blood to the lungs, where it releases carbon dioxide and picks up oxygen during respiration. Arteries are further divided in to very fine branches called the capillaries.

Circulation and Heart Valves Coronary circulation. Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are the coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.

- A stress myocardial perfusion scan is used to assess the blood flow to the heart muscle (myocardium) when it is stressed by exercise or medication and to determine what areas of the myocardium have decreased blood flow. This is done by injecting a radionuclide (thallium or technetium) into a vein in the arm or hand.

Cardiogenic shock Cardiogenic shock is a life-threatening medical condition resulting from an inadequate circulation of blood due to primary failure of the ventricles of the heart to function effectively. As this is a type of circulatory shock, there is insufficient perfusion of tissue to meet the demands for oxygen and nutrients.

- Cardiac tamponade , also known as pericardial tamponade , is when fluid in the pericardium (the sac around the heart ) builds up and results in compression of the heart . Onset may be rapid or more gradual. Symptoms typically include those of cardiogenic shock including shortness of breath , weakness, lightheadedness , and cough.

What is Perfusion? Perfusion refers to the flow of blood through the vessels of the body, on its way to the capillary beds in various tissues which receive bloodflow. When someone experiences decreased blood flow, this can be quite dangerous, as the tissues in the body can be quickly damaged by restricted bloodflow.

Coronary circulation Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.he left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum. The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left.

What is Perfusion Index (PI) Perfusion Index or PI is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is an indication of the pulse strength at the sensor site.

Extracorporeal Circulation methods of maintaining, with special apparatus, the circulation of blood and metabolism in the body or individual parts and organs of the body at an optimum level by perfusion (passage of blood or liquid blood substitute). Different methods of extracorporeal circulation are used, depending on the indications. General perfusion involves total exclusion of the heart and lungs from the blood circulation and their temporary replacement by a special device; it is used in certain operations on the heart and large blood vessels.

- Coronary Circulation. The heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right coronary artery supplies blood mainly to the right side of the heart.

What is Perfusion? Perfusion refers to the flow of blood through the veins and arteries of the body. Poor perfusion may cause organ failure. Perfusion is a common cause of amputation after an injury. In perfusion, blood moves from the heart, through a network of arteries and into the smallest blood vessels in the body.
