Cardiogenic Shock
Cardiogenic Shock
A condition where the heart can't pump enough blood to meet the body's needs, often due to a weakened heart muscle.

Septic Shock
Shock caused by a severe infection, leading to blood vessel leakage and vasodilation.

Study Notes
Cardiogenic Shock
- Characterized by pulmonary edema and impaired ventilation.
- Typically leads to decreased cardiac output and poor myocardial contractility.
Septic Shock
- Defined as shock due to severe infection.
- Involves bacterial damage to vessel walls, causing blood vessel leakage and vasodilation.
Other Types of Shock
- Neurogenic shock: Results from nervous system failure leading to widespread vasodilation.
- Obstructive shock: Often caused by conditions like cardiac tamponade.
- Distributive shock: Caused by widespread blood vessel dilation, leading to blood pooling in vascular beds.
Patient Assessment and Response
- Regular reassessment is critical, such as checking a stabilized patient's condition every 5 minutes during transport.
- In unresponsive patients with inadequate breathing, immediate airway obstruction checks are essential.
Anaphylactic Shock
- Subsequent exposure to allergens can lead to more severe reactions after initial sensitization.
- In cases of anaphylaxis, administering epinephrine intramuscularly may need to be repeated if there is no improvement.
Compensated vs. Decompensated Shock
- Compensated shock occurs when the body can maintain adequate circulation despite shock.
- Absent peripheral pulses indicate a progression to more severe shock, not compensated.
Management of Shock Situations
- In minor incidents like fainting, prioritize determining if there was an injury.
- For trauma patients, especially with potential intrathoracic bleeding, rapid transport to a trauma center is critical.
Important Considerations for Specific Populations
- In elderly patients, be cautious of delayed gastric emptying which increases vomiting risk.
Key Clinical Signs
- Indicators of compensated shock include normal blood pressure, while blood pressure may be the last measurable factor to change in shock.
- Severe events such as major trauma or chainsaw injuries require immediate direct pressure on wounds to control bleeding.
Emergency Interventions
- For uncontrolled bleeding, applying a tourniquet above the injury site can be necessary for severe lacerations.
