Lung injury refers to damage to the lung tissue that can impair its ability to function properly. This condition can result from various causes, including infections, exposure to harmful substances, or physical trauma. Symptoms may include difficulty breathing, coughing, and chest pain, which can vary in severity depending on the extent of the injury. Treatment for lung injury often involves addressing the underlying cause and may include medications, oxygen therapy, or mechanical ventilation in severe cases. Early diagnosis and intervention are crucial for improving outcomes and preventing long-term complications related to lung function.
