The difference between bright red and dark red blood in sputum mainly lies in whether or not the patient has active bleeding; active bleeding is bright red and inactive bleeding is dark red.
Blood in sputum is hemoptysis, and hemoptysis is seen in a variety of diseases, such as bronchodilatation, lung cancer, tuberculosis, Aureobasidium pneumonia, lung abscess and so on.
1. When there is active bleeding, blood in sputum is bright red, indicating that the bleeding is more urgent and the condition is progressing rapidly, requiring rapid treatment.
2. When there is inactive bleeding, the blood in the sputum is dark red, at this time, the disease may be longer, the bleeding has been for a period of time, in the bronchial tubes, the alveoli stay longer, so the color is darker.
Hemoptysis is also divided into small, medium and large amount of hemoptysis, if the amount of hemoptysis is large, it is easy to asphyxiate, at this time, it needs urgent treatment. If it is bronchial dilatation, it will be manifested as repeated hemoptysis. It is recommended that the patient consult a doctor in time to avoid delaying the condition.
