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.
