    Study Notes

    Circulatory Shock

    • Characterized by inadequate blood flow and oxygen delivery to tissues and organs

    Types of Circulatory Shock

    • Hypovolemic shock: caused by inadequate blood volume, leading to decreased cardiac output
    • Cardiogenic shock: caused by cardiac failure, leading to decreased cardiac output
    • Obstructive shock: caused by obstruction of blood flow, such as pulmonary embolism or cardiac tamponade
    • Distributive shock: caused by excessive vasodilation with maldistribution of blood flow
    • Septic shock: associated with severe infection and the systemic response to infection
    • Neurogenic shock: caused by a decrease in sympathetic control of blood vessel tone
    • Anaphylactic shock: the most severe systemic allergic reaction

    Clinical Manifestations

    • Hypovolemic shock: decreased blood pressure, tachycardia, decreased urine output
    • Cardiogenic shock: decreased cardiac output, decreased blood pressure, pulmonary edema
    • Obstructive shock: decreased cardiac output, decreased blood pressure, signs of obstruction
    • Distributive shock: decreased blood pressure, tachycardia, decreased peripheral resistance
    • Septic shock: fever, tachycardia, tachypnea, decreased blood pressure
    • Neurogenic shock: decreased blood pressure, bradycardia, decreased peripheral resistance
    • Anaphylactic shock: urticaria, angioedema, bronchospasm, decreased blood pressure

    Treatment Goals

    • Hypovolemic shock: restore blood volume and cardiac output
    • Cardiogenic shock: improve cardiac function and increase cardiac output
    • Obstructive shock: relieve obstruction and restore blood flow
    • Distributive shock: restore blood pressure and peripheral resistance
    • Septic shock: treat underlying infection and restore cardiovascular function
    • Anaphylactic shock: epinephrine, antihistamines, and corticosteroids to reverse allergic reaction

    Compensatory Mechanisms

    • Hypovolemic shock: vasoconstriction, tachycardia, and increased vasopressin to increase blood pressure
    • Cardiogenic shock: increased sympathetic tone to increase cardiac output
    • Distributive shock: vasoconstriction to increase blood pressure

    Other Key Facts

    • Can occur in the presence of normal vital signs
    • Learning objectives: understand the causes, symptoms, and treatment of circulatory shock
