常频机械通气是治疗新生儿呼吸衰竭的重要手段,患呼吸系统疾病的新生儿极易发生呼吸衰竭,故在新生儿重症监护室(NICU)中使用机械通气的频率较高。新生儿常频机械通气已在国内广泛应用,为使其应用规范化,达到更好的治疗效果,参考国内外新生儿常频机械通气的相关理论及临床经验, Frequent mechanical ventilation is an important treatment for neonatal respiratory failure. Newborn infants with respiratory diseases are at high risk of respiratory failure and are therefore more likely to use mechanical ventilation in the neonatal intensive care unit (NICU). Neonatal common-frequency mechanical ventilation has been widely used in China, in order to standardize its application to achieve better therapeutic effect, refer to the relevant theory and clinical experience of neonatal common-frequency mechanical ventilation at home and abroad,
