Hematologic Disorders 2 Flashcards
What causes shock? (circulatory system)
Circulatory system fails to maintain adequate pressure and perfuse the organs adequately
Shock leads to impaired:
cellular metabolism
Shock: Impaired cellular metabolism through these mechanisms
- Impaired oxygen use
- Impaired glucose use
Manifestations of shock vary based on
stage
Manifestations of shock often include:
- hypotension
- tachycardia
- increased respiratory rate
- cool extremities
- decreased pulses
- decreased urine output
- altered mental states
End result of shock
hypoxia to end-organ tissues
Shock: end result leads to hypoxia of end-organ tissues, especiall these
- kidneys
- brain
- heart
What are the 3 classes of shock?
- cardiogenic
- hypovolemic
- reduced system vascular resistance
Cardiogenic shock occurs due to
decreased cardiac output
Etiologic factors of cardiogenic shock
- arrhythmias
- acute MI
- severe CHF
- septic
- neurogenic
- cardiac tumor
Hypovolemic shock occurs due to
loss of whole blood or interstitial fluid
s/s of hypovolemic shock
- hemorrhage
- vomiting
- diarrhea
- dehydration
- burns
etiologic factors of shock that comes from reduced system vascular resistance
- SCI
- pain
- trauma
- anaphylaxis
- liver failure
