<prompt> Cushings phenomenon isLow BP high hea rateHigh BP high hea rateLow BP low hea rateHigh BP low hea rate  <response>: Cushing reflex tends to restore the blood flow to the medulla. Over a considerable range, the blood pressure rise is propoional to the increase in intracranial pressure. The rise in blood pressure causes a reflex decrease in hea rate the aerial baroreceptors. This is why bradycardia rather than tachycardia is characteristically seen in patients with increased intracranial pressure. Ref: Ganong;s Review of medical physiology 25th edition. Page:593
