Double lung inflammation is more serious and its severity is as follows: i. Patients have a wide range of lung infections and therefore decide to have a more serious condition. Such patients are mostly accompanied by varying degrees of cough, sputum, chills and fever. Second, patients are more likely to have complications related to inflammation of both lungs, making their condition more serious. For example, some patients with severe pneumonia have severe lung infections that lead to the formation of respiratory failure, which can sometimes progress to acute respiratory distress syndrome, or other organ function impairment. A small number of critically ill cases die clinically due to inflammation of both lungs, leading to the failure of multiple organs, especially in certain elderly patients. Therefore, when double lung inflammation occurs, it is important to pay attention to it and give appropriate anti-infective, supportive and symptomatic treatment as early as possible to prevent and treat the corresponding complications, improve the cure rate and improve the patient’s prognosis.
