Cold shock response is a series of neurogenic cardio-respiratory responses caused by sudden immersion in cold water. In cold water immersions, such as by falling through thin ice, cold shock response is perhaps the most common cause of death. [ 1 ]
In hypotonic solutions, water flows into the cell and the cell swells (turgescence). Osmotic shock or osmotic stress is physiologic dysfunction caused by a sudden change in the solute concentration around a cell, which causes a rapid change in the movement of water across its cell membrane.
The definition of refractory shock or vasodilatory shock varies. In 2018, the American College of Chest Physician stated that it is presents if there is an inadequate response to high-dose vasopressor therapy defined as ≥ 0.5 mg/kg/min norepinephrine-equivalent dose.
The characteristic triad of profound arterial hypotension, hemoconcentration (elevated hematocrit, leukocytosis, and thrombocytosis), and hypoalbuminemia in the absence of secondary causes of shock and infection, requires diagnosis in a monitored hospital setting during or after an acute episode. The fact that the condition is exceedingly rare ...
Sir Chris Hoy has said being diagnosed with cancer was the “biggest shock” of his life. The six-time Olympic champion revealed last month in a Sunday Times interview that his cancer is ...

Actor James Van Der Beek recently opened up about going “into shock” upon receiving his cancer diagnosis. Earlier this week, the 47-year-old revealed that he is battling stage 3 colorectal cancer.
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1] This may be followed by confusion, unconsciousness, or cardiac arrest, as complications worsen. [1]
