Shock Flashcards
Factors responsible for maintaining healthy cells
1) Blood Volume
2) Pump
3) Vascular tone
Factors responsible for systemic vascular resistance (most to least important)
1) Diameter
2) Viscosity
3) Length
Types of shock
1) Hypovolemic
2) Cardiogenic
3) Obstructive
4) Distributive shock
Hypovolemic shock
Loss of blood volume
Causes of hypovolemic shock
1) Loss of whole blood
2) Loss of fluids
Cardiogenic shock
impaired pump function, pump can’t contract adequately enough
Causes of cariogenic shock
1) myocardial infarction
2) cardiac myopathy
3) congenital heart defect
4) certain dysrhythmias
5) Valve disorders
Obstructive shock
blockage of blood flow in or out of thoracic vasculature
Causes of obstructive shock
1) Pulmonary embolus
2) Tension pneumothorax
3) Pericardial tamponade
Distributive shock
Caused by an imbalance in vascular tone
Types of distributive shock
1) Neurogenic
2) Septic
3) Anaphylactic
Neurogenic shock
Spinal chord injury at/above T6
Septic shock
Infection in blood system
Anaphylactic shock
Severe allergic reaction
Stages of shock
1) Initial stage
2) Compensatory stage
3) Progressive stage
4) Refractory stage
