Forced oscillation technique for determination of resistance to breathing in children.
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 ...
متن کاملRespiratory resistance by the forced oscillation technique in asthmatic children and cystic fibrosis patients.
Measurement of the total resistance of the respiratory system (Rrs) is an attractive alternative to measurement of forced expiratory volume in one second (FEV1) in young children because it requires minimal co-operation. The purpose of this study was to assess the ability of the forced oscillation technique (FOT) to detect airway obstruction in asthmatic children and in patients with cystic fib...
متن کاملNasal airflow resistance measurement: forced oscillation technique versus posterior rhinomanometry.
This study was designed to determine whether nasal airflow resistance (Rn) which is nonlinear during tidal breathing, can be assessed by the forced oscillation (FO) technique. Rn values obtained by the FO technique and extrapolated to 0 Hz (Rn,FO) were compared to those assessed by posterior rhinomanometry at maximal tidal inspiratory flow (Rn,m), at a 0.5 L x s(-1) flow (Rn,F), and at a 1 hPa ...
متن کاملForced oscillation total respiratory resistance and spontaneous breathing lung resistance in COPD patients.
Forced-oscillation total respiratory resistance (Rrs) has been shown to underestimate spontaneous breathing lung resistance (RL,sb) in patients with airway obstruction, probably owing to upper airway shunting. The present study reinvestigates that relationship in seven severely obstructed chronic obstructive pulmonary disease patients using a technique that minimizes that artefact. Rrs at 8 and...
متن کاملUsing the forced oscillation technique to evaluate respiratory resistance in individuals with silicosis.
OBJECTIVE To evaluate the resistance values obtained through the use of the forced oscillation technique in patients with varying degrees of airway obstruction resulting from silicosis. METHODS A total of 40 never-smoking volunteers were analyzed: 10 were healthy subjects with no history of pulmonary disease or silica exposure, and 30 had silicosis. The forced oscillation technique was used t...
