The results of our study show that: 1) most healthy subjects may develop flow limitation and hyperinflation during methacoline challenge in supine position, and 2) at onset of flow limitation there is little or no dyspnea, suggesting that the onset of dynamic airways compression per se does not elicit significant dyspnea. Significant dyspnea probably occurs with marked dynamic hyperinflation.
Flow limitation and dyspnea in normal supine subjects during methacholine challenge
VOLTA, Carlo Alberto;

Abstract
The results of our study show that: 1) most healthy subjects may develop flow limitation and hyperinflation during methacoline challenge in supine position, and 2) at onset of flow limitation there is little or no dyspnea, suggesting that the onset of dynamic airways compression per se does not elicit significant dyspnea. Significant dyspnea probably occurs with marked dynamic hyperinflation.File in questo prodotto:
