Cogswell, J. J. (1973). Archives of Disease in Childhood, 48, 259. Forced oscillation technique for determination of resistance to breathing in children. A method for measuring total respiratory resistance (RT) using a forced oscillation technique was applied to children between 3 and 12 years of age. RT at midinspiration was higher than airway resistance (Raw) measured on the same children by ...
In this paper, by constructing a class of Philos type functions on time scales, we investigate the oscillation of the following second-order forced nonlinear dynamic equation x(t)− p(t)|x(q(t))|x(q(t)) = e(t), t ∈ T where T is a time scale, p, e : T → R are right dense continuous functions with p > 0, λ > 1 is a constant, and q(t) = t or q(t) = σ(t). Our results not only unify the oscillation o...
A simplified method for monitoring respiratory impedance during continuous positive airway pressure.
The forced oscillation technique is useful in detecting changes in upper airway obstruction in patients with sleep apnoea undergoing continuous positive airway pressure (CPAP) ventilation. The aim of this study was to implement and evaluate a method for estimating respiratory impedance (Zrs) from the pressure and flow recorded at the inlet of the CPAP tubing. The method is based on correcting i...
BACKGROUND Monitoring of respiratory function is important in the diagnosis and management of respiratory disease. The forced oscillation technique requires minimal patient cooperation and is ideal for the determination of respiratory function in young children. This study aimed to develop reference ranges and to document the repeatability in healthy young children using commercially available ...
