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
