Bainbridge reflex physiology. [PubMed] [Google Scholar] Bainbridge FA. This reflex, first described by the British physiologist Francis Arthur Bainbridge in 1915, prevents the Jul 15, 2011 · The main objectives of this review are to summarize the history of the Bainbridge reflex, to describe its anatomy and physiology, and to evaluate the evidence for and against it having an influence on heart rate changes in the surgical patient. Some of these have homeostasis-maintaining roles, for example the baroreceptor reflex which maintains stable cardiac output and blood pressure. Jul 11, 2023 · The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. 1951 May;165(2):261–277. e. Jul 11, 2023 · The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. AVIADO DM, Jr, LI TH, KALOW W, SCHMIDT CF, TURNBULL GL, PESKIN GW, HESS ME, WEISS AJ. 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. [2] The reflex has become more widely known as the The Bainbridge reflex (or Bainbridge effect or atrial reflex) is a cardiovascular reflex causing an increase in heart rate in response to increased stretching of the wall of the right atrium and/or the inferior vena cava as a result of increased venous filling (i. Background and Physiology In 1915, a British physiologist named Francis A. This chapter will discuss, in detail, the physiology of the Bainbridge reflex including the function, the mechanism, and the clinical significance. , increased preload). Others, such as the oculocardiac reflex and the vasovagal reflex, are not homeostatic in their function, but Jul 11, 2023 · 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. 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. . [1] Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure Sep 29, 2021 · The reflex has become more widely known as the "atrial reflex," a fundamental principle in the cardiac physiology today. [PMC free article] [PubMed Sep 20, 2022 · Bainbridge's findings were confirmed a few years later by Sassa and Miyazaki, also in The Journal of Physiology, who further showed that increased mechanical tension along the atrial wall, caused by distending the auricles and the great veins with an inflatable balloon, was sufficient to induce the observed increase in heart rate (Sassa The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. 1915 Dec 24;50(2):65–84. Respiratory and circulatory reflexes from the perfused heart and pulmonary circulation of the dog. [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. Our main objectives in this review are to summarize the history of the Bainbridge reflex, to describe its anatomy and physiology, and to discuss the evidence for and against it having an influence on heart rate changes observed clinically. Aug 9, 2023 · The Bainbridge reflex is an important physiological mechanism that regulates cardiac function in response to changes in venous return. J Physiol. [2] The reflex has become more widely known as the "atrial reflex," a fundamental principle in the cardiac physiology today. This comprehensive article explores the anatomy and physiology of the Bainbridge reflex, including its underlying mechanisms, neural pathways, and clinical implications. Am J Physiol. The influence of venous filling upon the rate of the heart. Bainbridge published an observation that bears his name, which demonstrated that an intravenous infusion of saline or Aug 15, 2020 · Cardiac reflexes are reflex loops between the heart and central nervous system which regulate heart rate and peripheral vascular resistance. nkfoqezyhjmdzmoqfblmzjlqjzvvctsawvodqwkttrj
