Question

Differentiate among several types of shock: cardiogenic, hypovolemic, obstructive, distributive, and septic. Explain the pathophysiology of each.

Answer 1

Answer: Cardiogenic shock is a condition in which your heart suddenly can't pump enough blood to meet your body's needs. The condition is most often caused by a severe heart attack, but not everyone who has a heart attack has cardiogenic shock.

The pathophysiology includes the process in which there is a lack of oxygen to heart, usually from a heart attack, damages its main pumping chamber (left ventricle). Without oxygen-rich blood circulating to that area of the heart, the heart muscle can weaken and go into cardiogenic shock. Rarely, damage heart's right ventricle, which sends blood to your lungs to receive oxygen, leads to cardiogenic shock.

Hypovolemic shock is a condition in which the liquid portion of the blood (plasma) is too low. this is the most common shock, ans its pathophysiology includes vomiting, diarrhoea and excessive bleeding. This can lead to shock, a life-threatening condition in which the organs aren't getting enough blood or oxygen.

Obstructive shock is a form of shock associated with physical obstruction of the great vessels or the heart itself. Pulmonary embolism and cardiac tamponade are considered forms of obstructive shock. Obstructive shock has much in common with cardiogenic shock, and the two are frequently grouped together.

Septic shock involves a widespread infection causing organ failure and dangerously low blood pressure.Septic shock is a life-threatening condition caused by a severe localised or system-wide infection that requires immediate medical attention.
