Chapter 15 - Shock And Resuscitation Flashcards
What is inadequate volume?
A decrease of blood volume, which will decrease the preload, which will cause the stroke volume and cardiac output to fall, which will cause the systolic blood pressure to fall
What is shock?
Inadequate tissue perfusion
What is inadequate pump function?
When the heart does not generate enough force to move the necessary amount of blood through out the body
What is inadequate vessel tone?
When the vessels size increases because of massive vasodilation, the resistance decreases and the blood pressure and perfusion Olson decrease
What is hypovolemic shock?
Shock that is caused from a low volume of blood
What is the most common cause of hypovolemic shock?
Hemorrhage - the loss of whole blood
What is distributive shock?
A decrease in the inter vascular volume caused by massive systemic vasodilation and an increase in capillary permeability
What are the 5 categories of shock?
Hypovolemic, distributive, obstructive, cardiogenic
Metabolic/respiratory
What are the types of hypovolemic shock?
Hemorrhagic
Non hemorrhagic, burn
What are the types of distributive shock?
Septic
Neurogenic
Anaphylactic
What are the types of obstructive shock?
Pulmonic embolism
Pericardial tamponade
Tension pneumothorax
What are the types of cardiogenic shock?
MI, CHF
Beta blockers, calcium channel blockers
Abnormal rhythm
Depressed pump function
What are the types of metabolic/respiratory shock?
CO2, oxygen diffusion
What is cardiogenic shock?
Caused by ineffective pump function, usually when more than 40 percent of the left ventricle has been lost
What is obstructive shock?
Condition when blood is obstructed from moving forward
What is anaphylactic shock?
When chemical mediators are released that cause massive and systemic vasodilation
