Abstract

The forced oscillation technique (FOT) is a non-invasive technique for the assessment of respiratory mechanics. Since it does not require patient’s collaboration and it is not affected by spontaneous breathing, it can be used in evaluating lung function in non-invasive and invasive mechanical ventilation in order to adjust ventilation strategy accordingly. In particular, within-breath FOT allows the evaluation of the presence of expiratory flow limitation (EFL) and lung volume heterogeneity and recruitment, all of which are of great interest in clinical practice for tailoring mechanical ventilation according to the pathophysiological features of each individual subject. In patients with chronic obstructive pulmonary disease (COPD), FOT has been used to identify the lowest level of pressure able to abolish EFL during non-invasive mechanical ventilation, while in adults and newborns with respiratory distress syndrome, FOT has been used to identify the lowest level of PEEP that minimises heterogeneity in the ventilation and prevents lung collapse.
