A study done by the Respiratory Medicine Department at the University of Ioannina in Greece performed a validation study for the Air Next spirometer. The portable Air Next Spirometer is our certified CE Class IIA medical device.

air next During the study, the researchers conducted a descriptive, cross-sectional prospective study at the outpatient clinic of the Respiratory of Medicine Department of the University Hospital of Ioannina.

Two hundred consecutive patients and healthy volunteers with the following stratification participated in this study:

-50 patients with COPD -50 patients with asthma -50 patients with interstitial lung disease and restrictive spirometric pattern -50 health controls

All participants performed spirometry tests with a conventional desktop spirometer and with the Air Next spirometer. The following metrics were recorded based off the results:

Pearson correlation ICC
FEV1 0.976 0.976
FVC 0.963 0.962
FEV1/FVC 0.947 0.945
FEV 25%-75% 0.953 0.948

The objective of this study was to assess the accuracy and validity of these measurements by comparing them with the ones obtained with a conventional desktop spirometer.

The study concluded that portable spirometers feature multiple characteristic that makes them an ideal solution for extensive adoption in medical and non-medical settings. The Air Next spirometer is seen as an affordable and user friendly solution that does not need calibration and is operated using a smart-phone app. After careful and extensive validation, the results yielded by the Air Next and a conventional spirometer exhibited very good agreement and reproducibility. The study highlighted the quality of reported results and concluded that the Air Next is a reliable technology for screening and diagnosis of various spirometric patterns in clinical practice.
