The flashcards below were created by user tville01 on FreezingBlue Flashcards. What would you like to do?


  1. What are the three types of HF
    • right-side(cor pulmonale)
    • left-side( CHF)
    • high cardiac output
  2. What causes cor pulmonale
    • CHF
    • MI
    • pulmonary HTN
    • ARDS
    • COPD
  3. What will you see with cor pulmonale
    • Right=rest of body
    • peripheral edema
  4. What causes CHF
    • HTN
    • CAD
    • valvular disease(mitral/aortic)
  5. What will you see with CHF
    • decreased tissue perfusion
    • pulmonary edema
    • left=lungs
  6. What are the compensatory mechanisms for HF
    • SNS stimulation
    • Renin-angiotensin
    • myocardial hypertrophy
    • chemical responses
  7. How does SNS stimulation help HF
    • increased HR
    • Increased BP
    • increased CO
  8. How does the Renin-angiotensin help with HF
    vasconstriction and increased volume(Na+ & H2O reabsorbed)
  9. Which two compensatory mechanisms for HF increase the hearts need for O2
    • SNS stimulation
    • Renin-angiotensin
  10. How does myocardial hypertrophy help HF
    • bigger muscle=more forceful contractions
    • increased CO
  11. What is a good indicator that the body has proper perfusion
    kidneys, at least 30ml of urine output an hr(kidneys first effected by decreased perfusion)
  12. When collecting a history for HF what things should you be mindful of
    • DM
    • HTN
    • salt intake
    • hyperlipidemia
    • obestity
    • fluid retention
    • processes that contribute to HF
    • sleeping/breathing patterns
    • pillows for sleep
  13. What are s/s of CHF
    • impaired tissue perfusion
    • pulmonary congestion
    • weakness/fatigue
    • dizzy/acute confusion
    • SOB
    • olguria
  14. Upon auscultation what would you hear in a pt with CHF
    • wet lungs
    • S3
    • crackles
  15. What are s/s for cor pulmonale
    • peripheral edema
    • distended neck veins
    • ascities
    • dependent pitting edema
  16. What are the psychosocial concerns for HF patients
    • anxiety(can't breath), frustration leads to anxiety
    • Depression-life-style changes from disease process
  17. What lab values are looked at for HF
    • electrolytes
    • CBC-H&H
    • BNP
    • urinalysis
    • ABG
  18. when trying to get rid of edema what should you do
    give albumin then diuresis(only if protein deficiency is an issue)
  19. What imaging is done for HF pt
    • CXR(shows cardiomegaly, pleural effusion, pulmonary congestion)
    • echocardiogram(Best tool for HF)
  20. Why is echocardiogram the best tool for showing HF
    • nonivasive
    • shows valve changes
    • pericardial effusions
    • chamber enlargement
    • hypertrophy
    • measures EF
