Life-threatening asthma may be judged to be present in patients who, in the presence of a low FEV(1) are too dyspneic to speak, have altered consciousness or unequivocal cyanosis. Other physical signs which indicate airway obstruction of grave severity are pulsus paradoxus, gross thoracic overinflation and electrocardiographic evidence of pulmonary hypertension. A rise in the arterial CO(2) tension, the presence of pneumothorax or pneumomediastinum, and an FEV(1) less than 1 litre and vital capacity less than 0.5 litre, failing to increase immediately after inhalation of a bronchodilator, are also features which demand urgent and intensive therapy.Corticosteroids in large doses should be administered whenever a life-threatening situation is recognized. Systemic steroids should be stopped only when the danger phase, as indicated by the criteria given above, has been reversed. At all stages of therapy regular inhalations of a sympathomimetic bronchodilator should be maintained. Oral steroid therapy should be continued until maximum ventilatory function has been attained; only then should dose reduction be attempted.

In 5 Viennese general practice offices we investigated patients by spirometry with the following indications: differential diagnosis of dyspnea; every 3rd smoker of more than 10 cigarettes a day (including asymptomatic ones); cough and nasal disorders of more than 4 weeks duration; indicative physical findings (cyanosis or auscultation). The sample control group was matched for age and gender and did not have any symptoms characteristic of the indication group. Nevertheless a spirometric test was also carried out in these patients. A total of 212 patients were examined in 4673 consultations on 202 workdays in the 5 offices. In the group of 109 patients 62 (56.9%) had dyspnea and/or positive signs on auscultation. Of these 62 patients 39 (62.9%) had 1 or more positive findings either from PEF or FEV 1 or both. There were significantly more referrals for X-rays in case of abnormal lung function. The control group of 103 obviously healthy persons in particular showed a significantly higher number of abnormal PEF values than expected (31 persons, 30.1%).
