1

Anesthetized patients encounter respiratory depression from anesthetic drugs, so we supplement their oxygen to avoid hypoxemia. What is considered the minimum FIO2?

Minimum FIO2 = 35%

1

T/F: It is fine to use the quick flush valve on a small patient attached to a low volume breathing system because you're a badass and you play by your own rules

No. It's not.

You would pop your patient.

...wouldn't be very badass then.

2

What are the two main functions of any patient breathing system (PBS)?

  • Deliver oxygen +/- anesthetic gas
    • Eliminate carbon dioxide

2

According to the ACVA, how often should you record findings while an animal is under anesthesia?

Every 5-10 minutes

3

__________ bypasses the vaporizer and delivers O2 directly to the patient breathing circuit

Quick Flush

3

What flow rate is typically used with a non-rebreathing system?

200-300 ml/kg/min

Throughout the entire procedure

4

What is the equation you use to calculate proper size of rebreathing bag?

Body weight x Tidal volume x 5

  • Normal tidal volume = 10-20 mls/kg

5

The pressure reduction valve reduces cylinder pressure to a fixed _____ psi

50 psi

Provides a constant pressure of 50 psi to the flowmeter

5

What is the main function of the 'pop-off' valve?

limits pressure buildup within the circuit

ALWAYS keep open unless delivering manual, controlled, or assisted ventilation

6

Loss of sensitivity to pain is termed:

analgesia

6

At what temperature (Farenheit) do we consider the patient hypothermic?

96oF or less

Below 94oF anesthetic requirements are reduced, recovery may be prolonged, CV function depressed

7

How do you calculate remaining oxygen within an 'E' Cylinder?

8

A state characterized by CNS depression accompanied by drowsiness is termed:

sedation

9

What is the mechanism of action for Atropine?

Antimuscarinic

Competitively inhibits acetylcholine (and other cholinergic stimulators) at the postganglionic parasympathetic neuroeffector site

10

In order to avoid hypoxemia, N2O:O2 should not exceed a ratio of ____

2:1

11

What monitoring adjunct assesses the effects of anesthesia drugs on synaptic activity?

Electroencephalography (EEG)

12

A drug induced state of deep sleep from which a patient cannot be easily aroused:

narcosis

14

Is this an example of a VOC or VIC?

VOC

Vaporizer Out of Circuit. These are precision vaporizers.

14

What is the SVP for Desflurane at 20oC?

660 mmHg

14

T/F: Manual palpation of pulse provides an objective measure of adequacy of cardiac output and tissue perfusion

False

Manual palpation of pulse provides a subjective measure of adequacy of cardiac output and tissue perfusion

16

How many liters of oxygen can fit in an E Cylinder?

660 L

17

What is the reversal agent for dexmedetomidine?

Atipamezole

18

What is the SVP for Sevoflurane at 20oC?

160 mmHg

18

In an anesthesia machine, what flow meter is always last in the series?

Oxygen Flow Meter

21

At what pressure should E and H Cylinders be changed?

500 psi

22

T/F: Pin Index Safety System is used for E cylinders only

True!

The purpose of the PISS is to avoid improper cylinder connection (i.e. oxygen mismatch)

24

T/F: If no compensating mechanism is present, altitude can have an effect on output concentration of the anesthetic vaporizer

True

24

 T/F: There is an inverse relationship between temperature and saturated vapor pressure (SVP)

False

There is a direct relationship between temperature and saturated vapor pressure (SVP). As temperature increases, SVP increases.

26

As temperature increases, saturated vapor pressure (SVP) __________

increases

27

At what stage of anesthesia are vomiting and swallowing reflexes lost?

Stage III (Surgical Anesthesia)
