The Global Initiative for Asthma (GINA) works with health care professionals and public health officials around the world to reduce asthma prevalence, morbidity, and mortality. The gold standard in classifying severity of asthma is the GINA classification.
APACHE II uses a point score based upon initial values of 12 routine physiologic measurements, age, and previous health status to provide a general measure of severity of disease.
No angina with ordinary physical activity (e.g., walking, climbing stairs). Angina with strenuous or prolonged exertion.
Early-onset limitation of ordinary activity (e.g., walking rapidly or walking >2 blocks; climbing stairs rapidly or climbing >1 flight); angina may be worse after meals, in cold temperatures, or with emotional stress.
