What is the gold standard for COPD treatment?

The GOLD international COPD guidelines1, as well as national guidelines2, advise spirometry as the gold standard for accurate and repeatable measurement of lung function. Evidence is emerging that when spirometry confirms a COPD diagnosis, doctors initiate more appropriate treatment.

Similarly, how does GOLD classify COPD based on spirometry?

The diagnosis of COPD requires demonstration of an obstructive ventilatory defect in the spirometry, usually defined as a ratio of FEV₁ to forced vital capacity (FVC) below 70% (FEV₁/FVC < 0.7).

Keeping this in view, what is COPD GOLD C?

Based on all of these things — your symptoms, spirometry results, and exacerbation risk — your doctor will put your COPD into one of these groups: Group A: Low risk, fewer symptoms. Group B: Low risk, more symptoms. Group C: High risk, fewer symptoms.

What is COPD group C?

Group C (high risk/less symptoms): Stage III or IV, 2 or more per year 1 or more exacerbation with hospitalization, mMRC 0-1 or CAT less than 10. Group D (high risk/more symptoms): Stage III or IV, 2 or more per year 1 or more exacerbation with hospitalization, mMRC 2 or higher or CAT 10 or higher.

According to the GOLD guidelines, a person has stage 2 COPD if their FEV1 value is between 50 and 79%. FEV1 indicates the amount of air a person can forcefully exhale in 1 second as measured by a spirometry machine. It is of note, however, that the FEV1 measurement captures only one component of the COPD severity.
