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 use of forced oscillation technique in children with restrictive physiology. [PDF]
Breathe (Sheff)The forced oscillation technique (FOT) may not identify lung function abnormalities in children with restrictive physiology. FOT findings correlate poorly with spirometry and plethysmography testing in children with diffuse parenchymal lung disease. https://bit.ly/4h4liIh.

Forced oscillation of impulsive fractional partial differential equations
Partial Differential Equations in Applied Mathematics, 2023 In this paper, we investigate the forced oscillation of impulsive fractional partial differential equations. Some sufficient conditions are established which guarantee that the oscillation of the solutions by applying the integral transformation ...

A new estimator to minimize the error due to breathing in the measurement of respiratory impedance [PDF]
, 1988 This paper presents a new respiratory impedance estimator to minimize the error due to breathing. Its practical reliability was evaluated in a simulation using realistic signals.

Work-loop techniques for optimising nonlinear forced oscillators
CoRR, 2022 Linear and nonlinear resonant states can be restrictive: they exist at particular discrete states in frequency and/or elasticity, under particular (e.g., simple-harmonic) waveforms. In forced oscillators, this restrictiveness is an obstacle to system design and control modulation: altering the system elasticity, or modulating the response, would both ...

Respiratory oscillometry and functional analyses in patients with idiopathic scoliosis
Brazilian Journal of Medical and Biological Research, 2023 Scoliosis is a condition that affects the spine and causes chest rotation and trunk distortion. Individuals with severe deformities may experience dyspnea on exertion and develop respiratory failure.
