side to side啥意思？

A large-sized endotracheal suction catheter (12 french) is typically used to suction the stomach in an attempt to reduce the gastric volume and thereby reduce the aspiration risk. It must be clear that suctioning the stomach does not ensure an empty stomach, but it is recommended to reduce the gastric volume [42]. Orogastric suction is employed, and the patient is turned side to side with the catheter in place. Suction is intermittently applied. The catheter is removed, and the process is repeated once or twice until no fluid can be aspirated.

通常使用大尺寸的气管内抽吸导管(12法式)来抽吸胃，以试图减少胃容积，从而降低吸入风险。必须清楚的是，吸胃并不能保证空腹，但建议使用以减少胃容积[42]。采用口胃抽吸，导管到位后，病人侧身吸引，然后再向另一侧侧身后再吸引，间歇性地施加吸力。拔掉导管，重复这个过程一到两次，直到没有液体能被吸入为止。

side to side啥意思？从这个侧身到另一个侧身？
