What are the early symptoms of pulmonary obstruction

The lungs are the respiratory organs of the human body, located in the chest cavity, one of the two sides. A person's coughing and breathing are closely related to the lungs. The lung obstruction we are talking about today is pulmonary embolism, which means that a person's lungs are blocked by foreign objects, causing breathing difficulties or respiratory failure, and then coma and endangering life. This is a very life-threatening disease. If rescue is not timely, it may cause serious consequences. In fact, many people still lack basic understanding of pulmonary embolism, which makes it even more dangerous. You should know that its mortality rate in recent years is second only to cardiovascular and cerebrovascular diseases and cancer. Having said that, do you think it is necessary to understand pulmonary embolism? Then let’s first understand its early symptoms.

1. Difficulty breathing:

The most common early symptom of pulmonary embolism is dyspnea, which often occurs after exercise. Dyspnea may be related to respiratory and circulatory dysfunction. Breathing difficulties may be mild or severe. Sometimes they disappear quickly and recur after a few days or months. When mild breathing difficulties occur, they should be taken seriously.

2. Chest pain:

In addition to difficulty breathing, the early symptoms of pulmonary embolism are chest pain. A large number of people will have this symptom, which will occur suddenly, is mostly related to breathing, and worsens when coughing. Larger emboli may cause severe, crushing pain that is also located behind the sternum, difficult to tolerate, and radiates to the shoulder and chest.

3. Coughing and coughing up blood:

Patients with pulmonary embolism may also suffer from cough in the early stages, which is mostly dry cough, or with a small amount of white sputum, accompanied by wheezing. In severe cases, symptoms of coughing up blood may occur, indicating the occurrence of pulmonary infarction.

4. Abdominal pain:

Pulmonary embolism sometimes causes abdominal pain, which may also be related to irritation of the diaphragm. Some patients may experience syncope. The main cause of syncope is insufficient blood supply to the brain caused by massive pulmonary embolism.

5. Panic:

Patients with pulmonary embolism are more likely to experience unexplained panic and palpitations, which may be related to chest pain or hypoxemia.

6. Syncope:

The main cause of syncope in patients with pulmonary embolism is insufficient blood supply to the brain caused by more than 50% blockage of blood vessels. This may also be the only or earliest symptom of chronic thrombotic pulmonary hypertension and should be taken seriously. Most cases are accompanied by hypotension, right heart failure and hypoxemia. Although small emboli can cause syncope, large emboli are still considered the main cause of syncope.
