Antlia FOT Device for Early Lung Disease Detection: What You Need to Know
Antlia FOT Device is a lung function testing device based on the Forced Oscillation Technique (FOT) that evaluates respiratory mechanics during tidal (normal) breathing. Unlike conventional pulmonary function tests that require forceful inhalation or exhalation, Antlia FOT measures lung function while the patient breathes comfortably, making the test non-invasive, effort-independent, and easy to perform across all age groups, including children and the elderly. The system measures airway resistance and reactance across clinically relevant frequencies, providing insights into airway function with built-in quality control for reliable and reproducible results. its use the lung oscillometry.
The Antlia is a system that operates over a frequency range of 5 Hz to 20 Hz. It provides measurements using both sequential mono-frequency oscillations (5 Hz, 12 Hz, and 20 Hz) and multi-frequency oscillations covering 5–20 Hz simultaneously, enabling assessment of airway resistance and reactance across different regions of the respiratory system.
To ensure test quality and reproducibility, the device incorporates acceptability and repeatability criteria, including:
- Coefficient of Variation (COV) to assess within-test variability, and
- Coherence (COH) to confirm signal quality and reliability of measurements.
These quality indices help clinicians identify acceptable measurements and improve confidence in test interpretation.
This patient-friendly, quality-controlled testing approach makes Antlia Basic suitable for routine clinical assessments, screening, and evaluation of airway function, particularly in settings where patient cooperation or maximal respiratory effort may be difficult.

Clinical Applications of The Antlia.
The antlia supports screening, assessment, and monitoring of respiratory conditions such as asthma, COPD, bronchitis, emphysema, and interstitial lung diseases. It is also useful for bronchodilator response assessment, airway reversibility evaluation, and disease monitoring over time.
With minimal patient effort and reproducible measurements, Antlia Basic is well-suited for primary care, chest clinics, pediatric units, and community health programs.

Why Antlia Matters in Modern Lung Function Testing?
The Antlia plays an important role in advancing modern lung function testing by providing an accurate and non-invasive assessment of respiratory mechanics. Traditional lung function tests often require forced breathing manoeuvres, which can be difficult for pediatric, elderly, or critically ill patients. The Forced Oscillation Technique allows measurement during normal tidal breathing, making the process more comfortable and accessible.
This enables healthcare professionals and researchers to obtain reliable data on airway resistance and lung tissue properties without requiring complex patient cooperation. As a result, the Antlia supports early detection, monitoring, and research of respiratory conditions with improved efficiency and patient comfort.
GP Screening & Early Detection
Antlia is an effective first-line respiratory screening tool for general practitioners, enabling objective lung function assessment during routine consultations.
- Ideal for quick screening when spirometry is difficult to perform
