Traditional methods

A Lung function test (LFT) evaluates how well the lungs are working. The test measures how much air the lungs can hold, and how well a person can push air out of the lungs. The spirometry and body plethysmography are the most common instruments for lung function testing. The test are carried out by having a subject inhale air through a tube connected to an air flow meter that measures the volume of air inhaled or exhaled during a breathe cycle. A curve is generated showing the air flow as a function of time. The curve is analyzed for respiratory parameters.

The spirometry and body plethysmography do not pinpoint where functional deficits are present and cannot measure for compensation of different areas of lung.

Our unique approach

With the T-Sense collecting lung sounds from a plurality of sensors on the back of a subjects back. The recorded sound signals are processed to determine an average acoustic energy at the locations on the body surface over a duration of time. The total acoustic energy detected over the back of the subject correlates with the lung airflow.

The T-Sense platform estimates the airflow and plots the airflow as a function of time. The T-Sense and T-Lab can measure lung parameters like, Forced Expiratory Volume (FEV), FEV1, FEV1%, FVC, FVC%, FEV1/FVC ratio, PEF, FEF and the regional distribution of air.
