Airway Resistance Measurement in Children 3 to 6 Years of Age (ARC36)

Brief Summary:
In preschool aged children, the most suitable techniques to assess airway obstruction is debit interruption technic (Rint) and plethysmographic measure of specific airway resistance (sRaw). Even if Rint is easily and routinely performed, it also includes a component of lung tissue and chest wall resistance as well as respiratory tissue viscoelasticity. sRaw seems to be better for discriminating airway obstruction. These two techniques will be compared in terms of concordance in the diagnosis of pulmonary obstruction and bronchodilator response.

assessment of airway resistance

Primary Outcome Measures :
  1. airway resistance measure by interruption technique (Rint) [ Time Frame: Day one ]
    Rint is performed using Spiroteq Dyn'R during a 100 ms occlusion and calculated using the linear back extrapolation method

Secondary Outcome Measures :
  1. measure of bronchodilator response [ Time Frame: Day one ]
    Bronchodilator response is assessed with Rint and sRaw measurement
