Most of the elderly patients who feel breathless are due to inflammation in the trachea and lungs or bad heart condition. They need to go to the hospital for chest X-ray or CT lung examination, electrocardiogram and cardiac ultrasound examination, blood test, routine blood test and C-reactive protein test. After identifying the cause of the disease based on the test results, active treatment of the original disease with medication is required under the guidance of the doctor. If it is caused by pneumonia, it needs to be treated with effective antibacterial drugs, cough suppressing and expectorant drugs, and usually need to pay attention to rest and avoid overexertion. If it is caused by heart disease, it needs to be treated with heart-strengthening and diuretic drugs, and if the symptoms are serious, it can be treated with oxygen.
