高频振荡通气(HFOV)是减少早产儿慢性肺疾病的有效措施。2002年报告的英国多中心、随机对照振荡研究(the United kingdom oscillation study,UKOS)采用高容量通气策略的HFOV,极早产儿生后1 h内采用HFOV或常频通气(CMV)治疗未影响婴儿1岁时的肺功能,但该研究当时未评估婴儿的小气道功能。早期观察性随访研究发现,早期使用HFOV治疗的早产儿后期小气道功能优于CMV治 High frequency oscillatory ventilation (HFOV) is an effective measure to reduce chronic lung disease in preterm infants. The United Kingdom multicentre, United Kingdom, 2002 report of the HFOV with high-volume ventilation strategy in the United kingdom oscillation study (UKOS), HFOV with frequent pre-natal ventilation (CMV) within 1 h after preterm birth Pulmonary function at 1 year of age, but the study did not assess the infant’s airway function. Early observational follow-up study found that the early use of HFOV treatment of preterm children with small airway function better than CMV
