The diagnosis of pulmonary hemorrhage begins with the patient's history and symptoms, particularly signs such as coughing up blood (hemoptysis). This is followed by a physical examination. Radiological imaging methods are critically important in the diagnostic process, including a simple chest X-ray and contrast-enhanced thoracic computed tomography (CT) scan. Fiberoptic bronchoscopy is performed for definitive diagnosis and, if necessary, treatment. During bronchoscopy, a flexible device with an optical camera system at its tip is guided into the airways to directly identify the bleeding source. Local interventions, such as cold saline lavage and adrenaline injection, are then applied to the identified bleeding source to control the hemorrhage.
