20
Q

How is the size of the reservoir bag determined?

6x tidal volume (10mL/kg)= 60 mL/kg x the patients weight in kg

21
Q

Benefits of pre-oxygenation

Oxygen need for an induction box

A

4-5 L/min

23
Q

Pros of the induction box

A

Easy and good for wild or aggressive animals

24
Q

Oxygen need for dogs and cats

Q

When changing the position of the animal, always…

A

Disconnect the patient then reconnect

26
Q

What is the most reliable sign of inadequate anesthetic depth?

A

Responsive movement

27
Q

What is the normal ETCO2 awake and in an anesthetized state?

A

Normal= 25-40 mmHg; Anesthetized= 32-40 mmHg

28
Q

What should be done if the patient becomes hypotensive during anesthesia?

A

Administer crystalloid and/or colloid boluses

29
Q

Stage 1 of anesthesia

A

Period of voluntary movement

30
Q

Stage 2 of anesthesia

Period of involuntary movement

31
Q

Stage 3 Plane 1 of anesthesia

A

Intubation; unconscious but will react to pain/stimulation

32
Q

Stage 3 Plane 2 of anesthesia

A

The patients are deeply anesthetized (too deep)

34
Q

Stage 3 Plane 4 of anesthesia

A

Early anesthetic overdose

35
Q

Always assume that the patient is to…

A

Deep rather than too light

36
Q

What all is being monitored every 5 minutes?

A

Respiratory depth character and rate, MM color and CRT, HR and rhythm, pulse strength, jaw tone, eyes, oxygen flow rate and inhalant %, fluid drip rates, and temp

37
Q

Normal HR on a non-anesthetized patient
