Records of 304 patients with asthma and 25 with smoking related chronic airflow limitation were examined retrospective...
متن کاملJet and ultrasonic nebuliser output: use of a new method for direct measurement of aerosol output.
Output from jet nebulisers is calibrated traditionally by weighing them before and after nebulisation, but the assumption that the weight difference is a close measure of aerosol generation could be invalidated by the concomitant process of evaporation. A method has been developed for measuring aerosol output directly by using a solute (fluoride) tracer and aerosol impaction, and this has been ...

We have read with great interest the article by Castagnaro et al (October 1999),1 reporting a significant drop in oxygen saturation in the absence of an equivalent drop in FEV1 during sputum induction. This, however, has not been our experience. Although we agree that FEV1 may fall in asthmatics, COPD patients,2 and normal volunteers,3 we have not seen significant changes in oxygen saturation. ...
