Lab final

Question 1

An e-cyclinder contains how many PSI and Liters of Oxygen?

Answer 1

660 L and 2200 PSI

Question 2

What does a flow meter do?

Answer 2

1. A flowmeter controls the rate at which a specific gas is delivered
2. Flowmeter tubes are gas specific
3. Avoid excessive torque when closing flowmeters, because knobs can be twisted off
4. The oxygen flowmeter should always be downstream in the series

Question 3

What are the functions of the oxygen flush valve?

Answer 3

1. Bypasses vaporizer and delivers oxygen directly to the gas outlet
2. delivers oxygen to the circle at 35-75 L/min
3. Dilutes the anesthetic gases in the system

Question 4

Describe out of circuit vaporizers

Answer 4

• these vaporizers deliver a precise anesthetic concentration of anesthetic vapor
• gas within the vaporizer is split betwen the bypass and vaporization chamber
• VOC are agent specific
• output is NOT dependent on teh temperature and flow through the vaporizer

Question 5

A pressure reduction valve reduces cylinder pressure to a fixed

Answer 5

50 PSI

Question 6

Should you use the quick flush valve on a non-rebreathing system?

Answer 6

NEVER

Question 7

A charcoal canister filters what?

Answer 7

Iso/sevo

But NOT Nitrous oxide or carbon dioxide

Question 8

What is true about a rebreathing system?

Answer 8

1. contains soda lime
2. more resisitance and more componentss
3. less gas waste and atmosphere pollution
4. used in pts over 10kg
5. flow rate is 20-50

Question 9

What is a cause of this?

Answer 9

Rebreathing- doesn’t return to baseline

expired sodasorb

faculty expiratory valve

inadequate ins/exp flow

Question 10

What is the gold standard for measuring blood pressure?

Answer 10

Direct Arterial blood pressure

Question 11

What are the clinical uses for ECG?

Answer 11

1. Determine heart rate and rhythm
2. record electrical activity of the heart
3. determine cardiac oxygenation status
4. determine electroylyte abnormalities

NOT TO DETERMINE FUNCTION

90%

Question 16

What is the esphageal stehoscope used for?

Answer 16

Heart rate and respiratory rate

Question 17

What is the normal heart rate for a dog?

Answer 17

Question 18

What is the normal heart rate for a sheep?

Answer 18

60-90

Question 19

How often do you record vitals?

Answer 19

every 5 min

Question 20

What are the benefits of giving pre-anesthetic meds?

Answer 20

1. decreases the amount of inhalant
2. sedation to faciliate IV catheter
3. pre-emptive analgesia
4. decrease amount of induction agent needed
5. anxiolysis

Question 21

What is the most common drug types used in preanesthetic meds?

Answer 21

sedative +opoid

Question 22

What are the SE of ace?

Answer 22

1. anxiolysis
2. anti-emetic
3. inhibits platelet aggregation
4. hypotension

Question 23

MOA of butorphanol

Answer 23

mu anatgoinist, kappa agoinst

Question 24

what is the most common route for induction agents?

Answer 24

IV

Question 25

What are the negative effects of propofol?

Answer 25

Cardio and respiratory depression

Question 26

After induction agent has been administered, which signs of anesthetic depth should be assessed before attempting to open a canine pt's mouth for intubation?

Answer 26

Absent lateral palpebral reflex

Question 27

What are the negative consequences of an ET tube that is too small?

Answer 27

1. airway secretions may obstruct the tube 2. increased work of breathing via increase resisteance 3. over-inflated cuff causes trauma to the tracheal muscosa 4. it is possible that the system will have a leak and IPPV can NOT be administered if needed

Question 28

What methods are used to confirm ET tube placement?

Answer 28

* visualization * palpation * capnography

Answer 31

30-50 for maintenance

Question 32

What are complications associated with IPPV?

Answer 32

1. barotrauma from an APL valve left closed 2. decreased venous return 3. can deepen the anesthetic plane

Question 33

What predisposed a sheep to bloat post induction

Answer 33

1. Not fasting enough 2. esophageal intubation 3. atropine administration

Question 34
