This table presents data on the 3,997 of 5,815 patients (69%) who were admitted to the hospital following ALS transport for respiratory distress.
Categories are mutually exclusive and are defined by the following ICD-9-CM codes: congestive heart failure (428–428.9); pneumonia (480–487.0); acute respiratory failure (518.81, 518.82, 518.84); COPD (491–492.8, 493.2, 496); asthma (493.0, 493.1, 493.8, 493.9); acute myocardial infarction (410–410.91, excluding all 410.x2); pulmonary embolism (415.11–415.19); lung cancer (162.2–162.9).
