  1. DO2
    • delivery of oxygen to tissue
    • DO2 = CO x CaO2
  2. CaO2
    O2 content in arterial blood
  3. CO equation
    HR x SV
  4. CaO2 equation
    Hb  PaO2  SaO2
  5. SV factors
    • preload
    • contractility
    • afterload
  6. Determinants of MAP
    • Co x SVR
    • SVR = systemic vascular resistance
  7. Dexdomitor effects
    • Increases parasympathetic tone = decreased HR
    • Decreased sympathetic tone = decreased contractility
    • Vasoconstriction = Decreased overall perfusion and myocardial perfusion
  8. Zen Alpha
    • Medetomidine - alpha 2
    • Vatinoxan - peripheral alpha 2 antagonist
  9. Dexmedetomidine
    Alpha 2 agonist
  10. Zen Alpha effects
    • Increased parasympathetic tone = Decreased HR
    • Decreases in sympathetic tone = decreased contractility
    • Vasonconstriction - decreased overall perfusion and myocardial perfusion

    Vatinoxan = decrease in all above effects
  11. PaO2 of arterial blood gas at sea level and Boulder
    • 100 mmHg sea level
    • 75 mmHg Boulder
  12. PaO2 with dexdomitor at sea level and Boulder
    • Sea level = 70 mmHg
    • Boulder = 55 mmHg
  13. 90% on pulse-ox is equivalent to PaO2 of ______
    60 mmHg
  14. Dog alpha-2 protocol
    • Dexdomitor 0.005 mg/kg
    • Hydromorphone 0.1 mg/kg
    • +/- low dose anticholinergic Atropine 0.02 mg/kg

    • Zen Alpha dose on medetomidine 0.005 mg/kg
    • Hydromorphone 0.1 mg/kg
  15. Dexdomitor cat protocol
    • Dexdomitor 0.005 - 0.01 mg/kg
    • Hydromorphone 0.1 mg/kg
    • Typically NO anticholinergic
  16. Alfaxalone cat premedication
    • Alfaxalone 3-5 mg/kg
    • +/- hydromorphone 0.1 mg/kg (increases duration)
    • +/- midazolam 0.1 mg/kg (increases duration)
    • Can combine in 1 syringe
