  10. In what plane of stage III anesthesia do you see a more regular HR and RR but residual increase in HR and RR?
  11. In what plane of stage III anesthesia is there respiratory and CV function mildly depressed?
  12. In what plane of stage III anesthesia is there significant respiratory and CV depression?
  13. What reflects the alveolar concentration of inhalant anesthetic (brain partial pressure as well)?
    End expiratory anesthetic concentration
  14. What should you initially set the end tidal anesthetic concentration at?
    1.2-1.5X MAC
  15. How is mean arterial pressure related to cardiac output?
    MAP = CO x SVR
  16. What are some common parameters used to monitor adequate circulation? 6
    • Mucous membrane color
    • CRT
    • Heart rate
    • Electrocardiogram
    • Peripheral arterial pulse
    • Arterial blood pressure
  17. What does bright pink mucous membranes usually indicate?
  18. What is a normal CRT?
    Less than 2 seconds
  19. What is the normal HR range for a dog? cat?
    • Dog - 50-160 bpm

  22. What drugs can cause bradycardia? 4
    • Opioids (increased parasympathetic)
    • Anticholinesterases (increase acetylcholine)
    • Anesthetic overdose
