Which of the Following is an Advantage of Continuous Analysis

Question

Which of the following is an advantage of continuous analysis of expired gas during a DLCOsb test?
A) Instrument dead space is eliminated.
B) Exhaled gas concentrations can be visually inspected.
C) CO back pressure is reduced.
D) Breath-hold times longer than 12 seconds are acceptable.

Accepted Answer

Continuous analysis of expired gas during a DLCOsb test allows for the visual inspection of exhaled gas concentrations, which can provide valuable information about the patient's respiratory health. This can help to identify any potential issues or abnormalities in gas exchange that may not be detectable through other means. Additionally, this can help to ensure that the test is being performed accurately and that the patient is able to maintain an appropriate breath-hold time. However, it does not eliminate instrument dead space, reduce CO back pressure, or allow for breath-hold times longer than 12 seconds.
