The lungs exchange gases and also provide for some metabolic functions. Respiratory failure can be grouped into types I-IV. Type I (hypoxemic) and type II (hypercapnic) are the most prominent; type III is perioperative and often considered a subset of type I, while type IV is due to shock. Pulmonary urgencies and emergencies require rapid diagnosis and treatment in order to avoid morbidity and mortality. Identification of risk factors for desaturation and the application of an appropriate management algorithm can facilitate diagnosis and management. The ABCD-A SWIFT CHECK algorithm and its subalgorithms represent a logical approach to rapid diagnosis and management.
