Detection of small airway dysfunction using specific airway conductance.
STUDY OBJECTIVE To assess the potential utility of specific airway conductance (sGaw) in detecting small airways dysfunction, the postlung-transplant bronchiolitis obliterans syndrome (BOS) was used as a model of small airways dysfunction. BOS is defined as an otherwise unexplained 20% reduction in FEV1. We hypothesized that if sGaw is sensitive to small airways dysfunction, it should decrease ...
متن کاملPlethysmographic specific airway resistance.
sRaw measurements are feasible in children from 2 years of age. sRaw allows clinical monitoring and research during this critical period of growth and development in early life. sRaw measurements promise to bridge the gap of lung function measurements between infancy and school age.

متن کاملThe relationship between airway resistance, airway conductance and lung volume in subjects of different age and body size.
The resistance of the airways to the airflow through them depends on the radius, length and number of the airways. It has long been apparent (1, 2) that the bronchi are distended as well as lengthened in the inspiratory position of the lung. These two changes in the dimensions of these airways would have opposite effects on their resistance to airflow, lengthening increasing resistance and wide...
متن کاملFrequency dependence of specific airway resistance in a commercialized plethysmograph.
Specific airway resistance (sRaw) measured by body plethysmography has been shown to decrease markedly with decreasing breathing frequency when the inspired air is not conditioned to body temperature, atmospheric pressure and saturation with water vapour (BTPS). The phenomenon has been attributed to noninstantaneous gas warming and wetting in the airways. The aim of this investigation was to as...
