Etymology: Gk, hyper + dynamis, force
a cluster of symptoms that signals the onset of septic shock, often including a shaking chill, rapid rise in temperature, flushing of the skin, galloping pulse, and alternating rise and fall of the blood pressure. This is a medical emergency treated by keeping the patient warm, elevating the legs to assist venous return, administering IV fluids and antibiotics, and managing blood pressure. Nothing is given by mouth. The patient's head is turned to the side to prevent aspiration if there is vomiting. See also septic shock.
