Methods: Data from 200 patients aged 45-70 years were analyzed. Parameters such as age, sex, urban/rural location, education, smoking status, and time from first indicative spirometry test to official COPD diagnosis were recorded. Spirometry results (FEV1 and FEV1/FVC ratio) were examined, and correlations with COPD progression were assessed using the Pearson or Spearman rank correlation method.

Results: Our results demonstrated a delay in the official diagnosis of COPD from the first indicative spirometry test. The average FEV1 and FEV1/FVC ratio among the study population were 2.0 L and 0.70, respectively. A strong negative correlation was found between the spirometry results and the progression of COPD. Lower FEV1 or FEV1/FVC ratios corresponded to higher COPD severity.

Conclusion: This study highlights the vital role of spirometry in early COPD detection, diagnosis, and monitoring. The strong correlation between spirometry results and COPD progression suggests that spirometry is a robust tool for disease monitoring. Further research is needed to enhance early detection strategies and expedite diagnosis following initial spirometry indications.
