Shock Flashcards
Cardiogenic Shock
The inability of the heart to pump enough blood to supply all body parts.
What usually causes cardiogenic shock?
Severe left ventricular failure secondary to acute myocardial infarction congestive heart failure.
What are definitive signs of cardiogenic shock?
Pulmonary edema, Or other edema throughout the body, wheezing, crackles, or rales. Other signs include productive cough.
Hypovolemic shock
Shock to do too lost of intravascular fluid volume.
What are signs of hypovolemic shock?
Altered mental status pale, cool, and clammy. Blood-pressure maybe normal during compensated shock and then fall. Heart rate me being normal, Then increase, then fall; during decompensated shock.
Neurogenic shock
Results from injury to brain or spinal cord (CNS) causing interruption in nerve impulses to the arteries. This results in relative hypovolemia.
Signs of neurogenic shock
Warm, red, dry skin.
Anaphylactic shock
When he foreign substance enters the body and the immune system responds to rid the body of the invader.
Signs of anaphylactic shock
Skin
Flushed, itching, uticaria, swelling, cyanosis
Respiratory system
Breathing difficulty, sneezing, coughing, wheezing, Streiter, Laryngeal edema
Cardiovascular system
Vasodilation, Increased heart rate, decreased blood pressure
Gastrointestinal system
Nausea, vomiting, abdominal cramping, diarrhea
Nervous system
Altered mental status, Dizziness, headache, seizures, tearing
Septic shock
Begins with an infection enters the bloodstream and is carried throughout the body.
Signs of septic shock
In the beginning cardiac output is increased but vasodilation does not happen due to toxins. In later stages toxins have increased permeability of the blood vessels causing great amounts of fluid loss.
MODS
Multiple organ dysfunction syndrome
MODS occurs and how many stages
2
How does model progress?
Infection, Sepsis, Septic shock, MODS, Death
