Lung function parameters in stable state prior to ICU entry according to (A) reason for ICU admission and (B) ICU mortality. Boxes are interquartile ranges. Bars show range from 10th to 90th percentiles. When a patient was admitted several times, episodes were considered as new and independent events. Other causes were coma (epilepsy, n = 2, and benzodiazepin intoxication, n = 2) and follow-up after surgical treatment of pneumothorax (n = 2). Abbreviations: FEV1: forced expiratory volume in one second.
