Study Notes
Cardiogenic Shock
- Characterized by pulmonary edema and impaired ventilation.
- Resulting from decreased cardiac output and poor myocardial contractility.
Obstructive Shock
- Caused by conditions like cardiac tamponade, which obstruct blood flow.
Emergency Interventions
- Nonlifesaving interventions for multisystem trauma patients should occur en route to the hospital.
Signs of Shock
- Pale skin in a shock patient indicates peripheral vasoconstriction.
Distributive Shock
- Occurs due to widespread dilation of blood vessels, resulting in blood pooling in vascular beds.
Blood Pressure in Shock
- Blood pressure changes are often the last measurable factor during shock assessment.
Hypovolemic Shock
- Severe burns can lead to hypovolemic shock through loss of plasma.
Neurogenic Shock
- Commonly associated with hypothermia after acute spinal cord injuries.
Blood Flow Redistribution
- The body compensates for shock by directing blood flow away from less critical organs like the skin.
Septic Shock
- Results from severe infections leading to a systemic inflammatory response.
Anaphylactic Shock
- Commonly triggered by foods, medications, and insect stings.
Perfusion Triangle Components
- The three components essential for perfusion are the heart, blood vessels, and blood.
Trauma and Shock Survival
- For trauma patients, rapid transport to a trauma center significantly increases survival chances.
Compensated Shock
- A state where the body’s mechanisms maintain adequate circulation despite shock.
Tension Pneumothorax Treatment
- Immediate decompression of the injured chest side is critical to prevent death.
Managing Severe Bleeding
- The first action for severe leg bleeding is to control the bleeding effectively.
Older Patients and Shock
- In older patients, delayed gastric emptying can increase the risk of vomiting during shock.
Basic Definition of Shock
- Shock is defined as inadequate circulation of blood throughout the body.
Cardiogenic Performance
- Decreased cardiac output and poor myocardial contractility are indicative of cardiogenic shock.
Tourniquet Application
- For large lacerations with rapid bleeding, apply a tourniquet proximal to the injury site.
