EDAIC Anesthetic Equipment and Safety 5

Question 1

Which type of vaporizer is classified as 'out-of-circuit' and agent-specific, using a variable bypass design?

Accepted Answer

Tec-series (e.g., Tec 7) vaporizer

Answer

Tec-series vaporizers are out-of-circuit, agent-specific, variable-bypass vaporizers that split fresh gas flow between a bypass channel and a vaporizing chamber.

Question 2

The diameter index safety system (DISS) is used to prevent misconnection of:

Accepted Answer

Pipeline gas hoses to incorrect wall outlets

Answer

DISS uses unique threaded fittings of specific diameter for each gas to prevent incorrect pipeline hose connections to wall outlets or the anesthesia machine.

Question 3

A critical failure of the hypoxic guard (oxygen ratio monitor controller) would most likely result in:

Accepted Answer

Delivery of a hypoxic gas mixture to the patient

Answer

The hypoxic guard links oxygen and nitrous oxide flowmeters to prevent delivery of a nitrous oxide–oxygen mixture with less than 21–25% oxygen.

Question 4

When a breathing system leak test is performed and the circuit cannot maintain pressure at 30 cmH2O, the FIRST corrective action should be:

Accepted Answer

Systematically inspect all connections, the reservoir bag, and the CO2 absorber canister seal

Answer

A systematic check of all connections, the bag, and the canister seal identifies the most common sites of leak before replacing components or proceeding.

Question 5

Compound A, a nephrotoxic vinyl ether, is produced when which agent reacts with desiccated CO2 absorbent?

Accepted Answer

Sevoflurane

Answer

Sevoflurane reacts with desiccated CO2 absorbents (especially those containing strong bases like KOH) to produce Compound A, a potentially nephrotoxic vinyl ether.
