Breathing Systems Quiz

What happens to the exhaled air in a rebreathing system?

• It is expelled into the environment

• It is converted into oxygen

• It is breathed back in

• It is stored for later use

What is one of the advantages of rebreathing in anaesthesia for large patients?

• Higher flow rates

• More environmental contamination

• More heat loss

• Low flow rates so more economical

Which of the following is a disadvantage of rebreathing?

• Less heat loss

• Takes time to alter concentration of anaesthetic vapour

• Less environmental contamination

• More economical in large patients

What is a disadvantage of the CO2 absorbent and valves used in rebreathing systems?

• They decrease resistance

• They are less expensive

• They increase resistance

• They require less maintenance

Why might rebreathing systems be considered expensive?

• They use low flow rates

• They require less understanding of the system

• They often require more maintenance

• They result in more heat loss

Which of the following is not a type of non-rebreathing system?

• T-piece

• Bain

• Lack

• Circle

Is CO₂ absorbent needed in non-rebreathing systems?

• Yes, it is always needed

• No, it is not needed

• Yes, but only in certain types

• It depends on the patient

What is one of the advantages of non-rebreathing systems?

• High gas flow rates

• Rapid adjustment of inhaled concentration

• Increased environmental contamination

• Significant heat loss

Which of the following is a disadvantage of non-rebreathing systems?

• Easy to use

• Cheap

• Potential for inadvertent rebreathing if RR too high

• Minimal circuit resistance

What does APL stand for in medical terminology?

• Adjustable Pressure Limiting Valve

• Automatic Pressure Lever Valve

• Advanced Pressure Level Valve

• Adjustable Pain Limiting Valve
