Overview
The investigators will prospectively collect clinical information to develop a clustering analysis model and confirm phenotype for patients with acute respiratory failure who admit to the intensive care unit and require oxygen supply beyond a high flow nasal cannula, and a control group without acute respiratory failure. and clinical characteristics and prognosis will be compared.
