SHARE

The Forced Oscillation Technique (FOT) offers a modern and reliable but economical method for the impedance measurement of respiratory system. During test the patient is only asked to breath normally and no respiratory manoeuvre is needed. Since the test requires minimum co-operation from the patients, the FOT device is and uniquely applicable in paediatric pulmonology
