Q

isoflurane

A

purple

22
Q

halothane

A

red (highest risk)

23
Q

respiratory acidosis

A

deterioration, not enough oxygen

24
Q

vasodilation

A

widening of blood vessels

25
Q

hypoventilation

A

not enough air moving in and out of the lungs

26
Q

nitrous oxide

A

will replace oxygen
stored in blue compressed gas cylinders

27
Q

sevo induction/maintenance

A

4-6% induction
2-4.5% maintenance

28
Q

how much oxygen does anesthetized animals need?

A

30%

29
Q

small E tanks

A

660 L
attached to anesthesia machine or stored on cart

30
Q

large H tanks

A

6900 L
stored in a closet chained to the wall

31
Q

Oxygen is measured in?

A

Liters

32
Q

oxygen is measured in?

A

Psi

33
Q

tank pressure gauge

A

Attached to yoke of a machine or the pressure regulator of H tank

34
Q

why is the tank pressure gauge important?

A

indicated pressure or gas remaining in cylinder

35
Q

pressure-reducing valve

A

pressure regulator
reduce the pressure of the gas so that it is a safe pressure to be delivered to our patients

36
Q

oxygen flush valve

A

refill breathing bag, deliver pure oxygen to patient, dilute the anesthetic gas remaining in the circuit
this part is most commonly used when preparing a patient for recovery or when a crisis has arisen

37
Q

reservoir bag

A

just oxygen this part provides the patient an adequate volume of anesthesia gases during inspiration to fill the lungs

38
Q

pressure manometer

A

this part measures the pressure of the gases in the patients lungs

39
Q

compresses gas cylinder

A

when the oxygen inside this part is 500 psi, it should be changed

40
Q

line pressure gauge

A

this part measures the pressure in the line entering the flow meter

41
Q

pressure reducing valve

A

this part prevents rebreathing of CO2 and allows the anesthetist to tell if the patient is breathing

42
Q

vaporizer

A

carrier gas enters the part through the inlet part

43
Q

carbon dioxide absorber

A

this part should be emptied and refilled after 6-8 hours

44
Q

yoke

A

when the oxygen pressure inside this part is 500 psi, it should be changed

45
Q

negative pressure valve

A

this part prevent asphyxiation if the bag is empty

46
Q

tank pressure valve

A

when this part reads 1000psi, there Is 300L of oxygen left in the E tank

47
Q

flowmeter

A

this part reduces the pressure of the gas from 40-50psi

48
Q

pop-off valve

A

this part should be closed when bagging or ventilation the patient

49
Q

exhalation unidirectional valve

A

this part prevents the rebreathing of CO2 and allows the anesthetist to tell of the patient is breathing

50
Q

significant date to anesthesia

A

October 16th, 1846
