The triad of bradycardia, hypeension and irregular respiration is called as

A
Cushings reflex
B
Bezold Jarisch reflex
C
Bainbridge reflex
D

High-Yield Explanation
Cushing&;s reflex: Rise in blood pressure decreases hea rate aerial baroreceptor. Hence there is bradycardia, hypeension, and irregular respiration.Bainbridge reflex: Sudden rise in aerial pressure after rapid infusion of saline or blood produces tachycardia if the initial hea rate was low. The reflex helps to prevent damming of blood in the veins, atria and pulmonary circulation.Bezold-Jarisch reflex: Rapid breathing, hypotension, and bradycardia which occur following injection of ceain drugs like veratridine or nicotine into coronary aeries supplying left ventricle.Hering-Breuer reflex: produced on stimulation of irritant receptors in the bronchial epithelium due to distoion of the epithelium caused by large deflationary of the lungs. This reflex responsible for sighs or yawning.Ref: Medical physiology for UG students, Indu Khurana, pg 258,259,341
