5 types of Shock
Septic Shock
An acute infection, usually systemic, that overwhelms the body (toxic shock syndrome). Poisonous substances accumulate in bloodstream and blood pressure decreases, impairing blood flow to cells, tissues, and organs. What type of shock is this?
Septic
Common cause of death in ICU's (40% mortality). What type of shock is this?
Cardiogenic
Confusion, elevated preload, systemic and pulmonary edema, cyanosis, dyspnea, hypotension. What type of shock is this?
Hypovolemic
Confusion, increased SVR, vasoconstriction, cold, clammy skin, thristy, decreased urinary output, low CO, tachycardia, weak pulse. What type of shock is this?
Septic
Decreased BP, decreased CO, vasodilation, decreased SVR, tachycardia. What type of shock is this?
Neurogenic Shock
Injury or trauma to the nervous system (spinal cord, brain). Nerve impulse to blood vessels impaired, blood vessels remain dilated and blood pressure decreases. What type of shock is this?
Septic
Intervention: antimicrobials, cultures, give fluids. What type of shock is this?
Cardiogenic
Intervention: monitor fluids, give vasopressers, balloon pump or revascularization. What type of shock is this?
Anaphylaxis
Interventions: remove antigen, epinephrine, secure airways, give fluids. What type of shock is this?
Hypovolemic
May be caused by burns, hemorrhaging, dehydration. What type of shock is this?
Cardiogenic Shock
Myocardial Infarction with damage to heart muscle; heart unable to pump effectively. Inadequate cardiac output. Body cells do not receive enough oxygen. What type of shock is this?
Anaphylactic Shock
Results from reaction to substance to which patient is hypersensitive or allergic (allergen extracts, bee sting, medication, food). Outpouring of histamine results in dilation of blood vessels throughout the body. What type of shock is this?
Neurogenic
SVR decreases, blood pools but doesn't leave the body. What type of shock is this?
Hypovolemic Shock
Severe bleeding or loss of body fluid from trauma, burns, surgery, or dehydration from severe nausea and vomiting. Blood pressure decreases, thus blood flow is reduced to cells, tissue, and organs. What type of shock is this?
Cardiogenic
Type of shock with highest mortality rate
Anaphylaxis
Vasodilation, relative hypovolemic, dyspnea, edema, uticaria, hives, anxiousness. What type of shock is this?
Preload
What happens if too much fluid is given during heart failure
MODS (multiple organ dysfunction system)
What is it called when 2 or more organ systems fail?
Cardiac Output
What is low in all types of shock?
Decreased CO
What is the first step of the common pathway of shock?
Septic
What type of shock happens as a result of bacterial infection?
Neurogenic
What type of shock has widespread massive vasodilation?
Septic
What type of shock is most-commonly caused by gram-negative bacteria?
