Plethysmographic specific airway resistance.
نویسنده
چکیده
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.

Measurement of the specific airway resistance by plethysmography in young children accompanied by an adult.
The purpose of this study was to evaluate a procedure for measurement of specific airway resistance (sRaw) by whole body plethysmography in young awake children accompanied by an adult. sRaw was measured by a single-step procedure, omitting the measurement of the thoracic gas volume. The frequency dependency of sRaw was investigated and the accuracy of simulating body temperature, atmospheric p...
متن کاملPoor standardisation of plethysmographic specific airways resistance measurement despite widespread use.
Plethysmographic specific airways resistance (sRaw) has remained the most recognised measure of airway resistance for almost 60 years [1]. Studies in both adults and children (including preschoolers) suggest clinical utility across important obstructive lung diseases [2–5]. Measurement protocols based on rapid panting or tidal breathing exist, and are incorporated into many current commercial p...

متن کاملBronchial response time to a bronchodilating agent--orciprenaline.
The specific airway conductance (Gaw/Vtg) of 4 normal subjects and 5 subjects with respiratory diseases was measured before and after inhalation of orciprenaline. There was an almost maximum increase in Gaw/Vtg within 3 to 4 minutes in both groups of subjects after inhalation of orciprenaline. From the observed relatively rapid bronchodilatation, it would appear that the increased Gaw/Vtg is pr...
متن کاملLung hyperinflation and its reversibility in patients with airway obstruction of varying severity.
The natural history of lung hyperinflation in patients with airway obstruction is unknown. In particular, little information exists about the extent of air trapping and its reversibility to bronchodilator therapy in those with mild airway obstruction. We completed a retrospective analysis of data from individuals with airway obstruction who attended our pulmonary function laboratory and had ple...
