Pulmonary obstruction refers to pulmonary embolism, which is a general term for a group of diseases or clinical syndromes in which pulmonary circulation and right heart dysfunction are caused by obstruction of the pulmonary artery, or its branches, by exogenous or endogenous emboli.
Common diseases of pulmonary embolism include pulmonary thromboembolism, tumor embolism, amniotic fluid embolism, fat embolism, and air embolism. Typical symptoms of pulmonary embolism include dyspnea, chest pain, hemoptysis, cough, nervousness, and fainting.
The basic treatment for pulmonary embolism is medication, which can be categorized into anticoagulation, thrombolysis, and etiologic treatment. Commonly used anticoagulants include ordinary heparin, warfarin, low molecular heparin, etc. Commonly used thrombolytic drugs include streptokinase, urokinase, and recombinant tissue-type fibrinogen activator.
Pulmonary embolism can improve the symptoms and slow down the progress of the disease through active medication and surgery. It is also recommended that patients with pulmonary embolism should pay attention to their diet, drink more water, do more exercise, avoid sedentary behavior, and undergo regular checkups.
