Prone ventilation was proposed by foreign scholars in 1967 and has been widely used since then. The main indication is ARDS, also known as acute respiratory distress syndrome. The main indication is ARDS, also called acute respiratory distress syndrome. Only a small amount of lung can be ventilated in the solid part of the lung, that is, the distribution of the solid part and ventilation is not uniform, and the solid part cannot be ventilated during supine ventilation. Prone ventilation has been rapidly promoted in clinical practice, and in the case of burns, prone ventilation has also been well used. Since some patients have pneumonia, pulmonary edema, and pulmonary atelectasis after large burns, simple supine ventilation is not effective, and prone ventilation can achieve better results. In recent years, it has also been widely used in patients with new coronary pneumonia infection.
