Patterns of variation in airflow obstruction and risk of death in clinically stable asthma.

In an attempt to identify patterns of variation in airflow obstruction and to detect patients with marked bronchial lability, a factor reported to be associated with an increased risk of sudden asthma death, we obtained serial peak expiratory flow rate (PEFR) recordings from out-patients with chronic, clinically stable, asthma (N = 27) for one week.
