Pulmonary hematemesis is the symptom of vomiting and coughing up blood in the respiratory system. Clinically, the most common is the lesion of the respiratory system, for example, due to infectious factors, due to the infection of tuberculosis caused by Mycobacterium tuberculosis. Mycobacterium tuberculosis destroys the mucous membranes of the lungs, resulting in hemoptysis due to congestion, edema, and breakdown of the mucous membranes and rupture of the airways. It is also seen in trauma, such as hemothorax and hemopneumothorax due to contusion or contusion injuries to the lungs. In addition, it is also seen in occupational lesions of the lungs, especially bronchopulmonary carcinoma and alveolar cell carcinoma presenting with persistent cough and coughing up blood. In addition, it is also seen in cardiovascular system diseases, such as left heart failure and acute pulmonary edema. In this case, excessive fluid leakage from the lungs causes coughing up pink foamy sputum with red blood cells in the sputum.
