Comparison of peak expiratory flow and FEV1 admission criteria for acute bronchial asthma

Ann Emerg Med. 1982 Feb;11(2):64-9. doi: 10.1016/s0196-0644(82)80298-9.


One hundred nine episodes of acute bronchial asthma were studied utilizing PEFR and FEV1 measurements to determine objective patient disposition criteria. Of patients with both a pre-treatment PEFR less than 100 L/min, and a post-treatment value less than 300 L/min, 92% required admission or had an unsuccessful OPD course. Of patients with a pre-treatment PEFR less than 100 L/min and an improvement less than 60 L/min after initial terbutaline, 85% were admitted or had problems after discharge. PEFR correlated well with FEV1 at all stages of treatment.
