  1. A CRE is reviewing oximetry download data from a home sleep study. SpO2 fell below 88% for 15% of total recording time. This is documented as:

    Answer: CT90

    CT90 (cumulative time below 90% SpO2) is the standard metric used to quantify nocturnal hypoxemia burden in oximetry reports.

  2. When benchmarking a pulmonary rehab program, a CRE compares the program's outcomes to national AACVPR registry data. This is an example of:

    Answer: External benchmarking

    Comparing program outcomes to national registry standards is external benchmarking, used to evaluate performance against peer institutions.

  3. A respiratory educator graphs monthly asthma ED visit rates over 12 months and identifies an upward trend in winter months. This type of analysis is called:

    Answer: Seasonal trend analysis

    Identifying recurring patterns tied to time of year in time-series data is seasonal trend analysis.

  4. A CRE is preparing a report and wants to show the spread and distribution of CAT scores across 50 COPD patients. The most informative visualization is:

    Answer: Box plot

    A box plot displays median, quartiles, and outliers, making it ideal for showing distribution and variability of continuous scores.

  5. Sensitivity of a respiratory education screening tool is 85%. This means:

    Answer: 85% of true positives are correctly identified

    Sensitivity measures the proportion of true positives correctly identified by a test, reflecting its ability to detect disease.

  6. A CRE notices significant variability between two spirometry technicians' FVC measurements for the same patients. This is best addressed by evaluating:

    Answer: Inter-rater reliability

    Inter-rater reliability measures the consistency of results obtained by different testers, essential for standardizing spirometry quality.

  7. In a COPD education program audit, the number of patients who completed all 6 sessions divided by those who enrolled represents:

    Answer: Completion (adherence) rate

    The ratio of completers to enrollees is the program completion or adherence rate, a standard program effectiveness metric.
