高频通气(HFV)是机械呼吸近年来发展起来的一项新技术,由于它在临床上能解决像支气管胸膜瘘合并呼吸衰竭,婴儿呼吸窘迫综合征~2等这类过去难以解决的问题,而引起临床工作者的兴趣。它以近于或小于正常潮气量的通气方式维持生命所需要的气体交换,虽然其机制难以用传统的呼吸生理观点解释,但维持气体交换的效果已被公 High Frequency Ventilation (HFV) is a new technique developed in recent years for mechanical respiration. Because it can clinically solve the past difficult problems such as bronchopleural fistula with respiratory failure, Infant respiratory distress syndrome ~ 2, Which aroused the interest of clinicians. It maintains the gas exchange needed for life at or near the normal tidal volume, and although its mechanism is difficult to interpret with traditional respiratory physiology, the effect of maintaining gas exchange has been
