Significats de severe airflow en anglès

However, it is unclear whether BT is safe in patients with very severe airflow obstruction.

Methods: Prospective cohort study among participants in the NETT with emphysema and severe airflow limitation who were randomized to medical therapy.

Most cases remain stable over many years independent of the mode of presentation, although a few patients progress to severe airflow obstruction.

Conclusion: We suggest that BT may be safe for asthma patients with severe airflow obstruction and higher hospitalization rates than previously reported.

We sought to evaluate the co-morbidity profile and treatment patterns of "frequent exacerbators" with severe or very severe airflow limitation.

Both groups showed mainly stable disease without treatment, although one patient progressed to severe airflow obstruction and one was diagnosed at single lung transplantation.
