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 failure

Failure of the cardiovascular system to provide body tissues with enough blood for proper functioning. It may be caused by cardiac failure or peripheral circulatory failure, as occurs in shock, in which there is general peripheral vasodilation with pooling of blood in the expanded vascular space, resulting in decreased venous return.

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. 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 vaccination in the children could cause autism too. Is that true? Very recently I have delivered a cute male baby and I could see a change in me after my delivery in the sense that I always think about him. My sister’s son who is 5 years old is diagnosed with Autism and I just can’t see the sufferings of my sister with him. She experiences difficulty in almost all dealings with him right from brushing, giving bah and making him to study….etc. Now I fear that my son should not get in to autism although I know that this is too early to think about disorder in my son. But as my sister’s son got in to this disorder, this has affected me a lot. Hope you can understand my feelings towards my baby. When I browsed through the net, I was shocked to note that vaccination in the children could cause autism too. Is that true? Can I get some idea…..

A. Hey! I appreciate your care for the new born. But to be honest, fearing at this stage will only trouble you and your baby in the sense that your emotions could catch your baby especially when you breast feed. I want you to be cheerful so as to bring up a healthy child. The signs of autism in the new born are something which should not be thought about at this stage. All you may have to think is to bring up him nicely without any disease. As regards vaccinations that could create autism in children, there is no proof that a vaccine causes Autism. It is only a belief and all the children are vaccinated and not all get autism. It is not a fair idea to suspect vaccination as vaccinations are administered in a new born child after carrying out the necessary tests.

Q. Is electric shock efficient for ocd? Is it dangerous? My husband has OCD for 15 years now. He was also diagnosed with mania-depressia. He takes so many medications and nothing really helps. We were offered to try electric shock and I'm scared. Is it dangerous? What are the chances of this method to work for him?

A. Electroconvulsive therapy (ECT) is indeed considered effective for OCD, although it's not the first line of treatment. It does have its risks, including memory loss, disorientation and sort of confusion. There is also a change in the activity of the heart but it's rarely significant.

Generally it can be said that it's not an absolutely safe treatment, but it may help, especially if other drugs don't help.
