Hyperpnea-induced changes in parenchymal lung mechanics in normal subjects and in asthmatics.

Abstract

The effects of hyperpnea on parenchymal lung mechanics are unknown, but they may contribute to the resultant airflow limitation commonly seen in asthma. To investigate these effects, we measured the following parameters in seven asthmatic and six normal subjects before and after 5 min of hyperpnea: specific conductance, upstream resistance, static… (More)
