Meanings of chronic airflow in inglés

Methods: Twenty-four patients with chronic airflow limitation participated in a multiple crossover, randomized, placebo-controlled trial.

Background: Whether respiratory muscle training is of benefit to patients with chronic airflow limitation is controversial.

In contrast, the He dilution method can measure lower lung volumes in some patients with chronic airflow obstruction.

Conclusion: This training regimen fails to strengthen respiratory muscles or improve exercise or functional capacity in patients with chronic airflow limitation.

The optimal method of assessing the effect of treatment on the day-to-day function of patients with chronic airflow limitation is not established.

The objective of the study was to determine the effect of resistance breathing training on physiological and functional measures in patients with chronic airflow obstruction.
