Question 1

What is an anesthesia work station?

Answer 1

A device used to deliver a precise concentration of anesthetic gas to a patient for the induction and maintenance of anesthesia.

Question 2

What are the components of an anesthesia work station?

Answer 2

Vaporizer, flow meters, oxygen flush valve, ventilator, and monitors.

Question 3

What is the purpose of a vaporizer in an anesthesia work station?

Answer 3

To deliver a controlled amount of volatile anesthetic agent to the patient.

Question 4

What is the function of flow meters in an anesthesia work station?

Answer 4

To regulate the flow of oxygen and other gases to the patient.

Question 5

What does the oxygen flush valve do in an anesthesia work station?

Answer 5

Provides a rapid flow of oxygen to quickly flush out anesthetic gases from the breathing circuit.

Question 6

What is the role of the ventilator in an anesthesia work station?

Answer 6

To assist with the delivery of positive pressure ventilation to the patient.

Question 7

What type of monitors are typically included in an anesthesia work station?

Answer 7

Monitors for ECG, blood pressure, SpO2, end-tidal CO2, and anesthetic gas concentration.

Question 8

What is scavenging in the context of an anesthesia work station?

Answer 8

The removal of waste anesthetic gases from the operating room to prevent exposure to healthcare providers.

Question 9

What are the safety features of an anesthesia work station?

Answer 9

Pressure relief valve, oxygen failure protection device, and low oxygen pressure alarm.

Question 10

What is the purpose of the pressure relief valve in an anesthesia work station?

Answer 10

To prevent excessive pressure buildup in the breathing circuit.

Question 11

What is the function of the oxygen failure protection device in an anesthesia work station?

Answer 11

To ensure a continuous supply of oxygen to the patient in case of oxygen failure.

Question 12

What is the purpose of the low oxygen pressure alarm in an anesthesia work station?

Answer 12

To alert the anesthesia provider if the oxygen pressure drops below a safe level.

Question 13

What is the minimum oxygen concentration required in the breathing circuit of an anesthesia work station?

Answer 13

At least 21% to prevent hypoxemia.

Question 14

What is the role of the flow sensor in an anesthesia work station?

Answer 14

To measure and display the flow rate of gases delivered to the patient.

Question 15

What is the significance of the check valve in an anesthesia work station?

Answer 15

To prevent the backflow of gases and contamination of the system.

Question 16

What is the purpose of the carbon dioxide absorber in an anesthesia work station?

Answer 16

To remove exhaled carbon dioxide from the breathing circuit.

Question 17

What is the function of the heat and moisture exchanger in an anesthesia work station?

Answer 17

To warm and humidify the gases delivered to the patient to prevent mucosal irritation.

Question 18

What is the role of the pressure manometer in an anesthesia work station?

Answer 18

To monitor the pressure within the breathing circuit.

Question 19

What is the purpose of the APL valve in an anesthesia work station?

Answer 19

To release excess pressure in the breathing circuit to prevent barotrauma.

Question 20

What are the key principles of anesthetic machine checkout before each use?

Answer 20

Check for leaks, ensure proper functioning of monitors, verify gas supply, and perform a functional test.

Question 21

What should be done if a malfunction is detected during the anesthesia work station checkout?

Answer 21

Take the machine out of service and report the issue to biomedical engineering for repair.

Question 22

What is the purpose of the fail-safe valve in an anesthesia work station?

Answer 22

To prevent the delivery of hypoxic gas mixtures to the patient in case of oxygen failure.

Question 23

What is the recommended frequency for checking the anesthesia work station for leaks?

Answer 23

Before each case and after any significant change in the system.

Question 24

What are the potential hazards associated with anesthesia work stations?

Answer 24

Gas leaks, equipment malfunction, hypoxic gas mixtures, and barotrauma.

Question 25

What are the key safety guidelines for using an anesthesia work station?

Answer 25

Proper machine checkout, continuous monitoring, adherence to protocols, and prompt response to alarms.
