The flashcards below were created by user jld15 on FreezingBlue Flashcards. What would you like to do?


  1. PTT
    • Partial thromboplastin time
    • Chemical lab uses to get blood to clot
    • Measures effectiveness of heperain
  2. INR
    • International normalized ratio: 0.9- 1.1
    • 2-3
    • ----DVT, Afib, PE, post surgery DVT prophylaxis
    • 2.5-3.5
    • ----Valve replacement use
    • >3
    • ----risk for blood in joint
    • Since each labs chemicals are slightly different
  3. Therapist Considerations platelets
  4. Hgb/ Hct Therapist Considerations
    • <8 gm/dL/ <25%- essential ADLs, assist as needed for safety
    • <8-10 gm/dL/ 25-35%- essential ADLs, assist as needed for safety; light aerobics/weights (1-2 lbs)
    • >8 gm/dL/ >35%- amb and ADLs as tol; resistance exercises
  5. PLT Therapist Considerations
    • <10,000 and/or temp >100.5: no therapeutic exercise/Hold therapy
    • 10,000-20,000: therapeutic exercise/bike without resistance
    • >20,000: therapeutic exercise/bike with or without resistance
  6. Serum Chemistries (Lipids)
    • Cholesterol
    • Triglycerides
    • lipoproteins
  7. Cholesterols
    Lipids produced by the liver
  8. Triglycerides
    Fat in blood
  9. Lipoproteins
    • High density lipoprotein (HDL)-“good” or “healthy”
    • ----Take cholesterol out of blood
    • ----Increase through aerobic exercise, stop smoking, high fiber diet
    • Low density lipoprotein (LDL)-“bad” or “lousy”
    • ----Deposits in blood vessels
    • ----Decreased by weight loss
  10. Cardiovascular Tests
    • Homocysteine
    • C-reactive protein
    • BNP
  11. Homocysteine
    • Related to free radicals
    • Increase with age
    • ----But if increases too quickly then ages blood vessels quickly
  12. C-reactive protein
    • Produced by the liver
    • Systemic inflammation indicator
    • BNP
    • Brain natriuretic peptide
    • Released by stretching of the L ventricle
    • **Measure status of CHF
  13. Serum Enzymes/ cardiac enzymes
    • (looks at damage to cardiac muscles)
    • CK
    • Isoenzymes
    • ----CK-BB
    • ----CK-MB
    • ----CK-MM
    • Troponin
  14. Creatine kinase (CK) – formerly CPK
    • Sensitive marker for a MI
    • Shows up 3-6 hrs., peaks 18-24 hrs. after injury
    • Normalizes 2-3 days later
