Spirometric testing of FEV1 in acute asthma

ABSTRACT

Seventy patients of acute bronchial asthma were subjected to assessment of FEV1 [Forced Expiratory Volume in one second]. A significant disparity between clinical grade and FEV1 was observed. The decrease in FEV1 was more marked than in FVC. The study leads to an inference that, in acute bronchial asthma, the airway obstruction should be assessed by frequent monitoring of FEV1, and PEFR
