Airwave Oscillometry is a novel method for measuring lung function without patient effort and the most advanced form of Forced Oscillation Technique. The TremoFlo C-100, the world’s first Airwave Oscillometry System, accurately measures lung function by superimposing a gentle multi-frequency airwave onto the patient’s respiratory airflow. Throughout the AOS measurement, the patient just breathes normally. Although Spirometry is one of the most widely used tests to diagnose lung disease, its limitations are well-known but the tremoFlo C-100 AOS is a superb alternative for these situations. The tremoFlo allows you to effortlessly measure lung function in a wide range of settings.
