[3] [2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure. [4] In treating hypovolemic shock, it is important to determine the cause of the underlying hypovolemia, which may be the result of bleeding or other fluid losses.
Shock triggered by a serious allergic reaction is known as anaphylactic shock, shock triggered by severe dehydration or blood loss is known as hypovolemic shock, shock caused by sepsis is known as septic shock, etc. Shock itself is a life-threatening condition as a result of compromised body circulation.

Neurogenic shock results from damage to the spinal cord above the level of the 6th thoracic vertebra. [5] It is found in about half of people who have a spinal cord injury within the first 24 hours, and usually persists for one to three weeks. [5] Neurogenic shock may be caused by severe brain injury. [6]
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation .
In cardiogenic shock, the problem is in the function of the heart itself. In obstructive shock, the underlying problem is not the pump. Rather, the input into the heart (venous return) is decreased or the pressure against which the heart is pumping is higher than normal. [7] Treating the underlying cause can reverse the shock. [1]
Cardiogenic shock is most commonly precipitated by a heart attack. [4] Treatment of cardiogenic shock depends on the cause with the initial goals to improve blood flow to the body. If cardiogenic shock is due to a heart attack, attempts to open the heart's arteries may help. Certain medications, such as dobutamine and milrinone, improve the ...
Stock prices can move around a lot. Reading about the price swings and the day’s news often makes the volatility seem reasonable and other times it just adds to the confusion.
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]
