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
