Question 17

non-rebreathing systems should have maintenance flow rates that are:

Answer 17

very high - >100-200 mL/kg/min

Question 18

When is the negative pressure relief valve particularly important?

Answer 18

When there is a failure of O2 flow through the system.

Answer 20

The pop-off valve

Question 21

What can it mean when the reservoir bag that is not moving well?

Answer 21

• The ET tube is not in the trachea
• the animal has decreased tidal volume
• there is a leak around the ET tube

Question 22

How can an increase in anesthetic depth be achieved quickly?

Answer 22

• high O2 flow rates
• high vaporizer settings

Question 23

What factors can affect the concentration of anesthetic delivered from a nonprecision vaporizer?

Answer 23

• Temperature of the liquid anesthetic
• flow of carrier gas through the vaporizer
• back pressure
• type of anesthetic in the vaporizer.

Question 24

Answer 24

• 40-50 pst between the pressure-reducing valve and flowmeters
• 15 psi between the flowmeters and the breathing circuit
• 15 psi entering a VOC vaporizer.
