Types of Shock Chapter 6- DH 111
Hypovolemic Shock
 Most common.
 Decreases blood volume
 Causes: Bleeding, dehydration, vomiting, diarrhea
 Symptoms: Increased HR, Increased pulse, cool skin, decreased urine,
confusion
 Treatment:
1. Stop cause of bleeding or dehydration
2. Lay patient supine
3. Call EMS
4. CPR
5. Monitor vitals
6. Oxygen 4-6 L/min
7. IV fluids
Cardiogenic Shock
 Decreased circulation of blood caused by failure of the heart to function
effectively
 Causes: damage to the heart due to heat attacks, arrhythmias, cardiac
dysfunction
 Signs/Symptoms: Decreased BP, fast/weak pulse, cold/clammy skin,
cyanosis, chest pain, shortness of breath, decreased urine, confusion
 Treatment:
1. Lay patient supine
2. Call EMS
3. CPR
4. Monitor vitals
5. Oxygen 4-6 L/min
6. IV fluids
7. Cardiac Meds

Distributive Shock: Vasogenic- 3 types: anaphylactic, septic, neurogenic
Anaphylactic- Vasodilation and circulatory collapse due to exposure to an
allergen
Septic-Vasodilatory. Bacteria in blood stream causes an inflammatory response.
 Signs/Symptoms: Fever, increased cardiac output, swelling,
pink/warm skin, increased HR, thirst, respiratory failure.
 Result of a severe infection, multiple organ failure, death
Neurogenic- Loss of fight/flight response system in brain
 Caused by: emotional trauma, disease, drugs, tramatic injury to brain
or spinal cord
 Loss of sympathetic nerve activity causes expansion of blood vessels=
decrease in venous return= low cardiac output with low BP
 Sign/Symptoms: low BP, increased HR, brain and kidneys at risk of
failure
 Treatment:
1. Lay patient supine
2. Call EMS
3. CPR
4. Monitor vitals
5. Oxygen 4-6 L/min
6. Drug therapy to restore cardiac output
Obstructive Shock:
Decreased cardiac function and reduced circulation
 Causes: narrowing of arteries, pulmonary embolism, cardiac tamponade
 Symptoms: Decreased BP, shortness of breath
 Treatment:
1. Lay patient supine
2. Call EMS
3. CPR
4. Monitor vitals
5. Oxygen 4-6 L/min
6. IV fluids
7. Surgical intervention
