Physical Agents in Bronchial Provocation Tests: Nebulized Hypoosmolar Aerosol

  • L. Allegra

The bronchial challenge consisting in getting subjects to inhale ultrasonically nebulized distilled water (UNDW) has for some time now been adopted as an economical “physiological” method for documenting bronchial hyperreactivity [1, 2].
