Question

What is the primary function of the anesthetic breathing circuit?

A) Ventilate the patient.
B) Deliver oxygen and anesthesia gases to the patient.
C) Protect anesthesia staff from exposure to anesthetic gases.
D) Remove all CO2 from the gas mixture by conducting gas to a CO2 absorber.
E) All of the above.

Answer 1

The primary function of the anesthetic breathing circuit is to deliver oxygen and anesthetic gases, assist in ventilation, remove CO2, and protect staff from gas exposure, hence, all of the stated functions are correct.

Step-by-step explanation:

The primary function of the anesthetic breathing circuit is to deliver oxygen and anesthesia gases to the patient while removing carbon dioxide and providing a method for assisted or controlled ventilation. It also serves to protect the anesthesia staff from exposure to anesthetic gases and to ensure that the patient's respiratory system is supported throughout the procedure. As such, the correct answer to the question is E) All of the above. This circuit is an integral part of the anesthesia machine, which vaporizes liquid anesthetics and mixes them with oxygen and ambient air to provide a controlled concentration for patient inhalation.
