A modified forced oscillation technique for measurements of respiratory resistance
Journal of Applied Physiology, 1977 We present a modification of forced oscillation technique for automated determination of total respiratory resistance during inspiration. The modifications consist of a computerized signal averaging and an optimization technique in the assessment of the resistance value.

Forced oscillation technique as a predictor of FEV1 improvement in asthma
Respiratory Physiology & Neurobiology, 2017The usefulness of the forced oscillation technique (FOT) for predicting the treatment outcomes in untreated asthmatic patients is unknown. We investigated whether FOT could predict an improvement in FEV1 following treatment. FOT, spirometry, and fractional exhaled nitric oxide were performed in 31 outpatients before and after undergoing a minimum of ...

Low frequency forced oscillation technique in infants
, 1999 The respiratory system in infants undergoes profound changes in the first few years of life. We applied two adaptions of the FOT to characterise 1 ) changes in airway and parenchymal mechanics with growth in the first two years of life; 2) contribution of the nose to total respiratory impedance (Zrs); and 3) the influence of the chest wall to Zrs ...

The forced oscillation technique (FOT) is another application of the pressure oscillation method for lung diagnostics. It is based on the measurement of the respiratory impedance, which has evolved into powerful tools for assessing various mechanical phenomena in the mammalian lung during health and disease.

Comparison of Two Forced Oscillation Techniques
Respiration, 2009The forced oscillation technique developed by Korn et al. in 1979 (Siregnost FD 5) overestimates the measured resistances by about 20% in the range of resistance values met in healthy subjects and in patients. This is due to an overestimation of the impedance of the side tubing used for calibration.

Forced oscillation technique (FOT) is a noninvasive approach for assessing the mechanical properties of the respiratory system. The technique is based on applying a low-amplitude pressure oscillation to the airway opening and computing respiratory impedance defined as the complex ratio of oscillatory pressure and flow. Impedance data are interpreted in

The forced oscillation technique in children with respiratory disease
Pediatric Pulmonology, 1985AbstractThe single‐frequency forced oscillation technique was used to estimate the total respiratory impedance, resistance, and reactance at 2, 4, and 12 Hz of children who had cricoid stenosis (CS; n = 11), provoked bronchoconstriction (PB; n = 6), or cystic fibrosis (CF; n = 13).

FOT may hold the promise of improving the diagnosis of airway obstruction, but may be even better in quantifying the magnitude of airway reversibility and hyper-reactivity, helping in the adjustment of therapy, and monitoring disease progression in young children.

The Forced Oscillation Technique in Paediatric Respiratory Practice
Paediatric Respiratory Reviews, 2016The Forced Oscillation Technique (FOT) is a lung function modality based on the application of an external oscillatory signal in order to determine the mechanical response of the respiratory system. The method is in principal noninvasive and requires minimal patient cooperation, which makes it suitable for use in young paediatric patients.
