Forced Oscillations Technique (FOT), the reference method for respiratory mechanics in children.
The Q-i2m module is a forced oscillation technique (FOT) system for the measurement of the mechanical properties of the respiratory system, total respiratory input impedance (Zrs), under tidal breathing conditions.
Forced Oscillations Technique (FOT).
FOT has been recognised as a reliable method in the assessment of bronchial hyper-responsiveness in adults and children. Forced oscillation technique has been shown to be as sensitive as spirometry in detecting impairments of lung function.
Total Respiratory Impedance measurement by Pseudo Random Noise Signal.
Quark i2m measures total respiratory impedance by Pseudo Random Noise Signal, which consists of employing small amplitude pressure oscillations superimposed on the normal breathing.
No cooperation required from the patient.
FOT test with Q-i2m is non-invasive and requires minimal patient cooperation making the test ideal for uncooperative patients or for those unable to perform forced expiratory manoeuvres, such as children or elderly people.
Quick and easy assessment.
A simple and fast manoeuvre performed while the patient is breathing normally throughout the measuring device.
Accurate, reliable and reproducible technique.
FOT test provides accurate, reliable and reproducible results making it an ideal lung function test for epidemiological and field studies.
Integration with COSMED PFT lab.
Q-i2m module is suitable for COSMED Quark PFT, Q-Box and Quark Spiro, allowing thus the operator to manage, with one single PC program, tests of respiratory mechanics, diffusing lung capacity, static and dynamic lung volumes.
