Inhalation injuries occur when harmful substances are breathed into the lungs, often resulting from smoke, chemicals, or toxic gases. These injuries can lead to inflammation, airway obstruction, and respiratory distress, making it difficult for the body to get enough oxygen. Common causes include fires, industrial accidents, and exposure to hazardous materials. Symptoms of inhalation injuries may include coughing, wheezing, shortness of breath, and chest pain. Treatment often involves providing oxygen, medications to reduce inflammation, and in severe cases, mechanical ventilation. Early recognition and intervention are crucial for improving outcomes in affected individuals.
