Chapter 10 - Shock Flashcards
Define Shock
Failure of the circulatory system to maintain adequate blood flow to tissues
Define Shock
Failure of the circulatory system to maintain adequate blood flow to tissues
What is cardiac output?
The volume of blood pumped out of the heart each minute.
What is stroke volume?
The volume of blood pumped out of the heat’s left ventricle each contraction.
What is tachycardia?
A heart rate greater than 100 beats per minute in an adult.
What is tachypnea?
Respirations greater than 20 breaths per minute in adults.
What is compensated shock?
When the body is compensating for the shock and perfusing blood to tissues.
What is decompensated shock?
When the body can no longer compensate for the shock and the body’s systems begin to fail.
What are the four types of shock?
- Hypovolemic Shock
- Cardiogenic Shock
- Distributive Shock
- Obstructive Shock
What is Hypovolemic Shock?
Decrease in circulating blood volume.
What is Cardiogenic Shock?
When the heart cannot adequately pump blood.
What is Distributive Shock?
When blood vessels lose thier ability to constrict and maintain Bp.
What are the three kinds of distributive shock?
- Septic Shock - systemic infection
- Anaphylactic Shock - severe allergy
- Neurogenic Shock - Disruption in the nervous system.
What is Obstructive Shock?
SOme type of blockage prevents blood from reaching vital organs.
What is a tension pneumothorax?
When air enters the pleural space putting pressure on the heart and lungs.
What is cardiac output?
The volume of blood pumped out of the heart each minute.
What is stroke volume?
The volume of blood pumped out of the heat’s left ventricle each contraction.
