Describe the bainbridge reflex
WebThe Bainbridge reflex occurs when the heart rate increases in response to a rise in atrial pressure and this is a compensatory mechanism since increased right atrial pressures frequently result from elevated left heart pressures from decreased cardiac output. The Bainbridge reflex controls heart rate in response to blood volume and blood volume ... WebThe withdrawal reflex (nociceptive flexion reflex or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. The reflex rapidly coordinates the contractions of all the flexor muscles and the relaxations of the extensors in that limb causing sudden withdrawal from the potentially damaging stimulus. Spinal reflexes are …

WebBainbridge reflex, also called atrial 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. This reflex, first described by the British physiologist Francis Arthur Bainbridge in 1915, prevents the pooling of blood in the ... WebYour baroreceptor reflex is a series of quick actions your body takes to keep your blood pressure in a normal range in response to an abrupt change in position (particularly, a seated/lying down position to a standing position). It’s the most important way your body regulates blood pressure during these short-term events.
WebThe 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.

WebNeurogenic shock is even more of a threat, because the baroreceptor reflex can't function to increase cardiac output. Either way, deep shock, if not treated successfully within about 24 hours can result in such severe damage to sensitive organs that they cease functioning. Then, even if the patient recovers from the initial cause of the shock ... WebNov 11, 2011 · Bainbridge is best remembered for demonstrating that an increase in pressure on the venous side of the heart increased heart rate due to denervation of cardiac vagal influences. 10 The eponymous Bainbridge reflex is named after him, which is an increased heart rate due to an increase of the right atrial pressure. Bainbridge attributed …
The Bainbridge reflex or Bainbridge effect, also called the atrial reflex, is an increase in heart rate due to an increase in central venous pressure. Increased blood volume is detected by stretch receptors (Cardiac Receptors) located in both sides of atria at the venoatrial junctions. See more Francis Arthur Bainbridge described this as a reflex in 1918 when he was experimenting on dogs. Bainbridge found that infusing blood or saline into the animal increased heart rate. This phenomenon occurred even if … See more The Bainbridge reflex and the baroreceptor reflex control heart rate. The baroreceptor reflex can correct for a change in arterial pressure by increasing or decreasing heart rate. In contrast, … See more Bainbridge Reflex is involved in Respiratory Sinus Arrhythmia. During inhalation intrathoracic pressure decreases. It triggers increased venous return which is … See more Increased blood volume results in increased venous return to the heart, which leads to increased firing of B-fibers. B-fibers send signals to the brain (the afferent pathway of the neural portion of the Bainbridge reflex), which then modulates both … See more As venous return increases, the pressure in the superior and inferior vena cava increase. This results in an increase in the pressure of the right atrium, which stimulates the See more • Low pressure receptor zones • High pressure receptor zones See more
