Bainbridge reflex. [2] The reflex has become more widely known as the .

Bainbridge reflex. This reflex, first described by the British physiologist Francis Arthur Bainbridge in 1915, prevents the Jul 15, 2011 · The Bainbridge reflex is invoked throughout the anesthesia literature to describe the effect of changes in venous return on heart rate in patients in the surgical and critical care settings, but a critical analysis of the experimental and clinical evidence is lacking. [2] The reflex has become more widely known as the Bainbridge reflex, acceleration of the heart rate resulting from increased blood pressure in, or increased distension of, the large systemic veins and the right upper chamber of the heart. When disconnected from the body's central nervous system, when transplanted into another body, and even when excised and kept alive by suitable perfusion through the coronary vasculature, the heart continues to beat. The Bainbridge reflex is a compensatory mechanism that increases heart rate in response to increased atrial pressure. [1] Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure following administration of blood or saline. The spontaneous The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure fo … Aug 9, 2023 · The Bainbridge reflex is a physiological mechanism that regulates cardiac function in response to increased venous return. The reflex includes an increase i Sep 20, 2022 · The heart is the engine of blood circulation, so it should not be surprising that its vital role in maintaining life has evolved to be intricately autoregulated. [1] Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure . Aug 4, 2017 · Bainbridge反射，又称静脉心脏反射、心房反射，当心房压力升高时心率增快。这是一种代偿机制，右房压力增加通常是由心输出量减少引起的，升高心率会使心输出量增加。 Bainbridge反射与颈动脉压力感受性反射正好相对。后者是低血压或者血容量不足时，心脏拉伸幅度下降，反射性引起心率增加 Jul 11, 2023 · Introduction The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. [1] Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure following administration of blood or saline. Learn how stretch receptors, afferent and efferent pathways, and sympathetic activation are involved in this reflex and how it affects cardiac output and homeostasis. Others, such as the oculocardiac reflex and the vasovagal reflex, are not homeostatic in their function, but In this video, the Bainbridge reflex is discussed. This is one of the most important reflexes in the cardiovascular system. Learn about its history, mechanism, effects, and clinical relevance from this comprehensive article. The Bainbridge reflex is a cardiovascular reflex that increases heart rate in response to increased venous filling. Jul 11, 2023 · The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. It acts in opposition to the carotid baroreceptor reflex and may explain sinus arrhythmia. [2] The reflex has become more Aug 15, 2020 · Cardiac reflexes are reflex loops between the heart and central nervous system which regulate heart rate and peripheral vascular resistance. Some of these have homeostasis-maintaining roles, for example the baroreceptor reflex which maintains stable cardiac output and blood pressure. eeaw vnvqip lbqtr sanzpn ctrde ovzcsw gwl lwcgwne ckyvjna jzncg
