Plethysmographic 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 کاملFlow-Volume Parameters in COPD Related to Extended Measurements of Lung Volume, Diffusion, and Resistance
Classification of COPD into different GOLD stages is based on forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) but has shown to be of limited value. The aim of the study was to relate spirometry values to more advanced measures of lung function in COPD patients compared to healthy smokers. The lung function of 65 COPD patients and 34 healthy smokers was investigated using ...
متن کاملAirway Resistance and Lung Compliance
Lung compliance may be defined as the volume change per unit pressure change.8 It is an expression of the elastic-like properties of the lung if it is measured at points on a pressure-volume curve at which air is not moving into or out of the lung. These points of no air-flow occur near the end of inspiration and again near the end of expiration. Compliance does not include air resistive change...
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...
