Respiratory mechanics in ventilated COPD patients: forced oscillation versus occlusion techniques.
The respiratory mechanics of artificially ventilated chronic obstructive pulmonary disease (COPD) patients were investigated by means of the forced oscillation (FOT) and the end-inspiratory airway occlusion (AOT) techniques. FOT was applied to measure respiratory resistance (Rrs) and reactance (Xrs) from 0.25-16 Hz. Maximum (Rmax) and minimum (Rmin) resistances, static elastance (Est) and time ...
متن کاملForced oscillation assessment of respiratory mechanics in ventilated patients
The forced oscillation technique (FOT) is a method for non-invasively assessing respiratory mechanics that is applicable both in paralysed and non-paralysed patients. As the FOT requires a minimal modification of the conventional ventilation setting and does not interfere with the ventilation protocol, the technique is potentially useful to monitor patient mechanics during invasive and noninvas...
متن کاملRespiratory mechanics in mechanically ventilated patients.
Respiratory mechanics refers to the expression of lung function through measures of pressure and flow. From these measurements, a variety of derived indices can be determined, such as volume, compliance, resistance, and work of breathing. Plateau pressure is a measure of end-inspiratory distending pressure. It has become increasingly appreciated that end-inspiratory transpulmonary pressure (str...
متن کاملThe forced oscillation technique in intubated, mechanically-ventilated patients.
In a recent discussion concerning the use of the forced oscillation technique (FOT), PRIDE [ 1] stated that, although anaesthesia and intensive care are among the obvious areas of application of the method, there is very little information on these applications. The paper by PEsuN et al. [2] in the present issue of the Journal describes one of the first attempts to apply the FOT to mechanically...
متن کاملAssociation between respiratory impedance measured by forced oscillation technique and exacerbations in patients with COPD
Background It is well known that increased airflow limitation as measured by spirometry is associated with the risk of exacerbation in patients with COPD. The forced oscillation technique (FOT) is a noninvasive method used to assess respiratory impedance (resistance and reactance) with minimal patient cooperation required. The clinical utility of the FOT in assessing the risk of exacerbations o...
