circulatory arrest


Also found in: Dictionary, Thesaurus, Encyclopedia.

cir·cu·la·to·ry ar·rest

1. cessation of the circulation of blood as a result of ventricular standstill or fibrillation.
2. intentional cessation of circulation by temporarily stopping cardiopulmonary bypass flow during certain thoracic aortic operations; used with intentional profound total-body hypothermia to protect vital organs.

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.
