COPD, Chronic obstructive respiratory disease; Cardiac disease includes Ischaemic heart disease, congestive heart failure, arterial hypertension and angina pectoris, ICU, Intensive care unit; CRP, C‐reactive protein; Clinical and paraclinical characteristics upon admission of ICU‐patients admitted with respiratory disease. Numerical variables are presented as medians and interquartile range. Categorical data are presented as frequencies and percentages. Wilcoxon rank sum was used for numerical data, and Chi‐square test or Fisher's exact test, for categorical data.
