Oxygen therapy for cor pulmonale

Cor pulmonale is short for chronic pulmonary heart disease. It is normally caused by chronic lung diseases, most commonly chronic obstructive pulmonary disease. The main symptoms of patients are chronic cough, expectoration and other respiratory symptoms, as well as exertional shortness of breath, lower limb edema and other manifestations of right heart dysfunction. The primary treatment for cor pulmonale is to correct hypoxemia. However, due to pulmonary heart disease patients often accompanied by pulmonary ventilation function decline or even combined with carbon dioxide retention, so oxygen therapy should pay attention to oxygen concentration should not be too high, normal is low flow oxygen, in addition to oxygen therapy for a long time, so delay pulmonary vascular remodeling and pulmonary hypertension progress.
