Validation Studies

Rigorous bench testing and clinical cross-comparisons demonstrate the AlveoFlow system's reliability and high-fidelity data capture across all respiratory diagnostic parameters.

Accuracy Performance

98.4%

Mean agreement vs. gold-standard laboratory plethysmography across multiple lung volumes.

Clinical Precision

R² = 0.96

Strong linear correlation for airway resistance (Rrs) measurements between 5Hz and 20Hz frequencies.

Reproducibility Index

< 3.0%

Coefficient of variation (CV%) maintained across consecutive trials with diverse patterns.

ATS/ERS Compliance

100%

Full technical adherence to standard technical requirements for clinical oscillometry diagnostics.

Respiratory Use Cases

  • Asthma & Airway Hyper-responsiveness
  • COPD & Small Airway Disease
  • Post-COVID Respiratory Management
  • Lung Transplant Rejection Monitoring
  • Interstitial Lung Disease (ILD) Monitoring
Small-Airway Sensitivity

Identify distal airway dysfunction that spirometry often fails to detect, enabling intervention months earlier.

Effortless Monitoring

Obtain highly reproducible data during normal tidal breathing, removing the variability of forced exhalation maneuvers.

Clinical ROI

Reduce repeat testing and diagnostic delays, leading to optimized clinic throughput and improved patient management.
