The innovative tremoflo C-100 Airwave Oscillometry System (AOS) offers fast, easy assessment of large and small airway function. Measurements are obtained during tidal breathing and without patient effort. The tremoflo is excellently suited for a wide range of patients, from preschoolers to the elderly.

Outcomes

1. Fast & Easy

To assess respiratory function, the tremoflo adds a gentle oscillatory wave to the patient’s regular, quiet breathing. A measurement duration of only 20 seconds allows three repetitions within a couple of minutes.

2. Outcomes

The tremoflo provides curves of Resistance (R) and Reactance (X) as well as parameters reflecting large and small airway function.

3. Central Obstruction

An obstruction of the large, central airways causes a parallel upward shift in R while X remains largely unchanged.

4. Peripheral Obstruction

Obstruction of the small airways in the peripheral lung causes a downward shift in X along with an increase in R. In presence of heterogeneities, R also becomes curved.

Expert Opinions

Oscillometry offers “an in-office tool that can assess peripheral airway impairment even in young children and may detect airway obstruction earlier than spirometry.”

“Monitoring small airway function by [Oscillometry] can be useful in identifying patients who are at risk for losing asthma control, and in assisting with clinical decisions and treatment plans.” Bickel et al., Chest 2014

“In studies that use both [oscillometry] and spirometry, [oscillometry] is more useful than spirometry in children in differentiating asthma from healthy cohorts” Galant et al., AAAAI 2017 Oscillometry “has been found to be useful in measuring response to bronchodilators, such as salbutamol and ipratropium, in patients with asthma and COPD.”

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
