What Is a Pulmonary Contusion?

A pulmonary contusion is a bruise of the lung tissue, often resulting from trauma such as a car accident or a fall. This injury causes bleeding and inflammation within the lung, leading to breathing difficulties and pain. Understanding its symptoms and treatment is crucial for recovery. How does this impact the body's overall function? Continue with us to uncover the effects.

A pulmonary contusion, also known as a lung contusion, occurs when the lung is injured by external trauma. The damage to the lung can cause a range of symptoms including shortness of breath, chest pain, and problems breathing. Diagnosis of a lung contusion can be suspected based on the patient’s symptoms, but is often best confirmed by imaging studies including chest x-rays or computed tomography (CT) scans. Treatment of the condition focuses on offering patients respiratory support to give their damaged lungs a chance to heal.

In short, a pulmonary contusion can be thought of as a bruise of the lung. Being exposed to trauma — for example, from a car accident — can damage the wall of the chest and the lung tissue located inside of the body. The damaged tissue bleeds, and cannot properly expand with air as the patient breathes in and out.

Symptoms of a pulmonary contusion can vary depending on the severity of the injury. One of the most common symptoms is shortness of breath. Affected patients might need to breathe in at a faster rate compared to healthy people, and might not be able to breathe in as deeply compared to other people. Other symptoms can include pain located in the chest wall, coughing, and pain with breathing. Severely affected patients might not get enough oxygen, and can develop life-threatening symptoms, such as unconsciousness. Often it takes between two to three days before the damage causes symptoms to occur.

Diagnosis of a pulmonary contusion focuses on integrating symptoms, physical exam findings, and results of imaging studies. On examining patients with this condition, doctors or other health care professionals might note that patients appear to be having difficult time breathing. They might have external signs of trauma, such as bruising or bleeding of the skin. On chest x-ray, a lung contusion might appear as a visual abnormality of the lung tissue. A CT scan of the chest is more sensitive in picking up this type of injury.

Treatment of a pulmonary contusion is typically supportive. In other words, there is no true cure for the condition, but the symptoms patients experience from the injury can be alleviated. For shortness of breath, patients can be given supplemental oxygen, administered through a face mask or nasal probe. In severe cases, patients can be intubated in order to ensure they obtain the oxygen they need while getting rid of the carbon dioxide produced by the body. With these supportive measures, the lung is given an opportunity to heal itself and re-establish normal respiratory function.
