Week 4

Question 1

What is the function of an Oxygen Generator?

Answer 1

generates oxygen instead of gas cylinder/ pipe-line

Question 2

What is the function of an Pressure Gauge?

Answer 2

provides visual amount of gas left within cylinder- NOT RELIABLE FOR NITROUS OXIDE LEVELS

Question 3

What is the function of an Pressure Reducing Level?

Answer 3

reduces pressure of gas coming from cylinder, maintains constant pressure- prevents surge

Question 4

What is the function of an Flowmeter?

Answer 4

allows manual adjustment of gas volume delivered to patient, final stage of gas reduction

Question 5

What is the function of an Emergency Oxygen Flush?

Answer 5

provides oxygen directly from cylinder to pipe-line, bypassing vaporiser

Question 6

What is the function of an Oxygen Failure Alarm?

Answer 6

alerts if drops in oxygen occurs- risk of cyanotic blue MM- lack of oxygen

Question 7

What is the function of an Mini-Schrader Sockets?

Answer 7

provides oxygen/ air supply to power ventilators

Question 8

State the stages of an Oxygen Flow Machine?

Answer 8

Oxygen enters machine at lower, back of flowmeter

Oxygen exits flowmeter at the top

Oxygen enters vapouriser, collects anesthetic agents (isoflurane)

Oxygen/ agent mixture exits vapouriser

Gas and agent enters breathing bag, inhalation tube by patient

Question 9

What is the function of an Vaporiser?

Answer 9

compensates if temperature changes, ensures maintenance of constant concentrations of inhalant agent- delivered in mixture
CANNOT CHANGE DIAL- unless direct BY VET
