circulatory failure

circulatory failure

Etymology: L, circulatio + fallere, to deceive

inability of the cardiovascular system to supply the cells of the body with enough oxygenated blood to meet their metabolic demands. The condition may result from abnormal cardiac function, as in myocardial infarction; from an inadequate circulating volume of blood, as occurs in hemorrhage; or from mass systemic vasodilation, as may occur in gram-negative septicemia. See also shock.

circulatory

pertaining to circulation.

circulatory arrest

see cardiac arrest.

circulatory collapse

shock; circulatory insufficiency without congestive heart failure.

circulatory failure

includes cardiac or central circulatory failure and peripheral circulatory failure. Although the mechanisms, causes and clinical syndromes are different the pathogenesis is the same, the circulatory system fails to maintain the supply of oxygen and other nutrients to the tissues and to remove the carbon dioxide and other metabolites from them. The failure may be hypovolemic, distributive.

circulatory response

changes in the cardiac and vascular functions in response to such factors as emotional stress, physical exercise, temperature change.

circulatory shock

see shock.

circulatory support

see extracorporeal circulation.

circulatory system

the major system concerned with the movement of blood and lymph; it consists of the heart and blood vessels. The circulatory system transports to the tissues and organs of the body the oxygen, nutritive substances, immune substances, hormones and chemicals necessary for normal function and activities; it also carries away waste products and carbon dioxide. It helps to regulate body temperature and helps maintain normal water and electrolyte balance.

The rate of blood flow through the vessels depends upon several factors: force of the heartbeat, rate of the heartbeat, venous return and control of the arterioles and capillaries by chemical, neural and thermal stimuli.

Patient discussion about circulatory failure.

Q. I'M 56 YEARS OLD FEMALE, PRETTY GOOD HEALTH. BUT LATELY I BEEN HAVING LIKE ELECTRIC SHOCK ON MY BODY.

A. How about medication withdrawl? Sometimes patients withdrawing from depression/anxiety medications will feel what is commonly descibed as "brief electic shock" or "shock-fright" If you are on any meds you may want to read the labels or consult a professional about blood levels

Q. SHOCK-WHAT IS IT? clinical anaphylactic shock

A. shock is when the fluid volume in the blood decreases to a dangerous amount. then the body "panics" because most of the organs don't get oxygen and don't remove carbon dioxide and die. so the body start to shut down "unnecessary" organ's blood flow. like skin and such.

Q. I was shocked to note that genes play a vital role in building muscles Is this possible? I am , 20 years old. I am always dreaming to build muscle like my favorite hero who maintains 8 abs. Anybody can dream but to live that dream is a difficult task. Out of curiosity, I had discussed my desire to build muscles with my friends. But I was shocked to note that genes play a vital role in building muscles. My family doesn’t have a history of muscles and this fact has put me in to a difficult situation. Is this possible…If so, how can I live my dream? If the family doesn’t have a history of muscle growth, then what happens to the generation which follows them? I need a positive feedback to my query……

A. there's a genetic potential for fitness, like there is a genetic connection and potential for inelegance. but no matter how smart are your parents- if you won't study you won't live that potential, and some one who doesn't have that genetic ability and will study- will be better. the same thing with physical fitness.
