Impulse oscillometry (IOS) can detect early small airway diseases in cleaning workers. While initial tests showed differences, adjusted analysis indicated work duration, sex, age, BMI, and smoking explained these findings.
Area of Science:
- Occupational Health
- Respiratory Medicine
- Pulmonology
Background:
- Cleaning workers are potentially exposed to respiratory irritants.
- Early detection of small airway pathologies is crucial for preventing chronic respiratory diseases.
Purpose of the Study:
- To evaluate the utility of impulse oscillometry (IOS) for early detection of small airway pathologies in cleaning workers.
- To compare lung function parameters between cleaning workers and a control group.
Main Methods:
- A cross-sectional study involving 121 cleaning workers and 123 controls.
- Impulse oscillometry (IOS) was used to assess airway disease-related measurements (R5%, R20%, R5-20%, AX, Fres).
- Standard spirometry (FEV1/FVC, PEF, MMEF, FEF25, FEF75) was also performed.
Main Results:
- IOS measurements were significantly higher in cleaning workers, indicating increased airway resistance.
- Cleaning workers exhibited significantly lower spirometry values (FEV1/FVC, PEF, MMEF, FEF25, FEF75).
- After adjusting for work duration, sex, age, BMI, and smoking using General Linear Models (GLM), occupational differences in lung function and IOS were not significant.
Conclusions:
- Impulse oscillometry (IOS) shows potential for the early detection of airway diseases.
- Factors such as work duration, sex, age, BMI, and smoking significantly influence lung function parameters and IOS measurements in cleaning workers.

Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
