“…3,103,105 Patients who present with pretreatment FEV 1 or peak expiratory flow less than 25%-30% of predicted and those with values after treatment that are less than 40% of predicted should usually be admitted to hospital. 1,2,84,161 Patients who achieve FEV 1 or peak expiratory flow of at least 60% of predicted can usually be discharged safely, 84,162,163 provided adequate postdischarge care and follow-up are assured. For patients with intermediate FEV 1 or peak expiratory flow values (i.e., 40%-60% of predicted) after treatment, decision-making must be individualized on the basis of the examining physician's knowledge of the patient's previous ability to manage an exacerbation, the likelihood that the patient will be adherent with medications and instructions, and the home or environmental circumstances to which the patient will return.…”
