Question

Which of the following would correctly identify a leak in an oxygen flow tube?

A) Positive-pressure leak check
B) Oxygen analyzer
C) Negative-pressure leak test
D) All of the above
E) None of the above

Answer 1

To identify a leak in an oxygen flow tube, the correct test is the Negative-pressure leak test.

Step-by-step explanation:

To identify a leak in an oxygen flow tube, the correct test to use is the Negative-pressure leak test. This test involves creating a negative pressure inside the tube and observing if there is any air entering. If there is a leak, air will enter the tube, indicating a problem. The other options provided, such as the Positive-pressure leak check and Oxygen analyzer, are not suitable for identifying leaks in an oxygen flow tube.
