Background
Access to spirometry, a test for lung function, is often limited because traditional spirometers are expensive and not easy to use. This can make it hard to diagnose and manage chronic respiratory diseases like COPD and asthma. Portable spirometers could be a better option since they are cheaper, easier to use, and more convenient to carry.
Study Overview
This study aimed to compare the reliability and usability of a portable spirometer (Medcaptain VC-30 Pro) with a standard laboratory spirometer (Jaeger MasterScreen PFT). A total of 132 participants from two hospitals took lung function tests using both devices.
Methodology
Participants performed various lung function tests, measuring important outcomes like:
- Forced expiratory volume in one second (FEV1)
- Forced vital capacity (FVC)
- Peak expiratory flow (PEF)
- And several others.
Additionally, 30 healthy volunteers were tested on their own after guidance to assess how easy the portable device was to use.
Results
Out of 132 participants, 126 achieved valid test results. The correlation between the two spirometers was very high:
- FEV1: 0.994
- FVC: 0.993
Most results (96%) fell within acceptable limits, indicating that the portable spirometer is reliable. The agreement on diagnosing lung issues was also strong, with high scores for severity classification.
In the usability test, 28 out of 30 volunteers rated the portable spirometer as easy to use.
Conclusions
The portable spirometer showed excellent reliability and usability compared to the laboratory spirometer. Non-specialists can effectively use this device to get accurate results.
Opportunities for Clinics and Patients
Based on the study findings, clinics can:
- Implement portable spirometers for easier access to lung function testing.
- Train staff to use these devices effectively.
- Use AI tools to track and analyze patient data for better management of respiratory diseases.
Next Steps
Start with a pilot project using portable spirometers, monitor the results, and evaluate the impact on patient care. For further assistance with AI solutions in healthcare management, please contact us:
