We can determine whether the coughing blood comes from the lungs by the following aspects:
1. Blood volume coughed up: The amount of blood coughed up by the lungs was usually larger, while the amount of blood coughed up by the throat was smaller.
2. The nature and color of coughing blood: If the blood and phlegm that is spat out are evenly mixed, it is mainly deep lung bleeding. If the blood was dark red, it usually meant that the lungs were coughing up blood.
3. " To determine the primary disease: There are many reasons for coughing up blood in the lungs, such as lung cancer or tumors, which may cause coughing up blood.
However, these methods of judgment were not particularly accurate. In order to determine where the blood came from, it was recommended to perform a mammoscopy and chest CT to determine the location of the tumor.
In a Naruto coughing fanfiction, it could be a sign of a more serious illness. Maybe he was poisoned during a battle, and the coughing is the first symptom. His enemies might be trying to use this to their advantage, but Naruto, being the determined ninja he is, still tries to fight back while dealing with his coughing fits.
Coughing up blood was a symptom, usually referring to coughing up bright red blood. There were many reasons for hemoptysis, including bronchial disease, lung disease, cardiac disease, general system disease, and drug factors. The specific reason needed to be confirmed through the relevant examinations and medical history collection in the hospital. The common possible causes included bronchiectasis, lung cancer, lung edema, and so on. If hemoptysis occurs, it is recommended to seek medical attention in time to determine the specific cause and carry out targeted treatment.
The symptoms of hemoptysis in lung cancer were dark red or brown bloody phlegm, frequent hemoptysis, and hemoptysis after severe coughing. If the patient found that the color of hemoptysis was dark red or brown bloody phlegm, frequent and repeated hemoptysis, or sudden obvious hemoptysis during violent coughing, these may indicate that they may have lung cancer. However, the symptoms of hemoptysis alone could not determine whether it was lung cancer. Other preliminary screening methods, such as imaging, were needed. Therefore, one could not determine whether one had lung cancer just by coughing up blood.
A plot could center around Naruto coughing as a side - effect of a new power he's acquired. This new power might be unstable, and the coughing is the physical manifestation of that instability. His friends are concerned and start to research how to help him. Naruto, on the other hand, is excited about the new power and wants to keep exploring it, even if it means dealing with the coughing. This creates a conflict between his own desires and the well - being advice of his friends.
It could be a sign of a major turning point. If Naruto starts coughing up blood, it might signal that he's in a really dangerous situation and needs to find a way to get out of it fast. This can lead to new adventures as he searches for a cure or a way to regain his strength.
He could be secretly worried. Snape might use his knowledge of potions and dark magic to try and find a cure or at least a way to stop the bleeding. He may also be conflicted, as his past relationship with Harry and his loyalty to different sides in the wizarding world play a role in how much he wants to help Harry.
