Comparison of Two Forced Oscillation Techniques

Respiration, 1984
The 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 in Spinal Muscular Atrophy

Chest, 2014
Spinal muscular atrophy (SMA) causes respiratory compromise that is difficult to assess in young children. The forced oscillation technique (FOT) is commercially available for children as young as 2 years of age and is nonvolitional. The aim of this study was to assess the usefulness of FOT in young children with SMA.Children with SMA aged < 10 years ...

Optoelectronic Frequency Stabilization Techniques in Forced Oscillators

2021
Forced frequency stabilization techniques of self-injection locking (SIL) and self-phase locked loop (SPLL) have been demonstrated to be effective for phase noise reduction. In SIL scheme, a portion of the oscillator output is directly injected back to the oscillator after passing through a long delay while in SPLL, the delayed signal is used to ...

Forced oscillation technique may identify severe asthma

The Journal of Allergy and Clinical Immunology: In Practice, 2019
Background: Fixed airflow obstruction in severe asthma is usually assessed by spirometry. However, the role of the forced oscillation technique (FOT) in severe asthma is unknown. We hypothesised that FOT would be useful to diagnose severe asthma and discriminate it from non-severe asthma. Aims: In this cross-sectional study, we assessed the usefulness

Forced Oscillation Technique

2014
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

Forced oscillation technique: comparison of two devices

Journal of Applied Physiology, 1985
The respiratory impedances in healthy subjects and patients with advanced obstructive lung disease were measured between 2 and 32 Hz, using two forced oscillation techniques: the setup used previously by Grimby et al. (J. Clin. Invest. 47: 1455–1465, 1968) and a modified device in which the pneumotachograph is replaced by a 2-m-long tube and the ratio
