PATHOPHYSIOLOGY OF CIRCULATORY SHOCK Circulatory shock refers to generalised inadequate blood flow through the body to the extent that the body tissues are damaged, especially due to too little oxygen and other nutrients are delivered to the tissue cells. PHYSIOLOGICAL CAUSES OF SHOCK Circulatory shock caused by decreased cardiac output may be due to two factors: 1. Cardiac abnormalities that decrease the heart's ability to pump blood: MI, severe heart valve dysfunction, heart arrhythmias are some among them. Circulatory shock that originates as a result of cardiac weakness is termed as cardiogenic shock. 2. Factors that decrease venous return: due to hypovolemia, decreased vascular tone or obstruction to blood flow at some point in the circulation. Circulatory shock without diminished cardiac output may be due to 1. Excessive metabolic rate 2. Abnormal tissue perfusion patterns At times, a person may be in severe shock and still have an almost normal arterial pressure due to strong nervous reflexes that prevent the arterial pressure from falling. At other times, the person may not be in shock but the arterial blood pressure may fall up to half of normal. Once circulatory shock r ...
