Abstract

Objectives: To analyse deviation of ventilator parameters from their set targets during high-frequency oscillatory ventilation (HFOV) with or without volume guarantee (VG) and compare the two modes during emergency neonatal transport.

Study design: Retrospective observational study using the fabian™ HFOi ventilator.

Results: Median deviation of mean airway pressure from the set value was <1 cmH₂O. During HFOV the pressure amplitude differed from the set value by <1 cmH₂O. During HFOV-VG median deviation of the oscillation volume (VThf) from the targeted value was -0.07 mL/kg, but in some cases VThf was by >0.38 mL/kg below target. Setting maximum allowed amplitude 10 cmH₂O above the usually required amplitude improved maintenance of VThf. HFOV and HFOV-VG parameters were similar, except the lower amplitude during HFOV without VG. VThf <2.5 mL/kg avoided hypercapnia in most cases.

Conclusions: HFOV and HFOV-VG maintain ventilator parameters close to their targets and are promising modalities during neonatal transport.

新生儿转运过程中的高频振荡通气（带或不带容量保证）。

目的分析高频振荡通气（HFOV）过程中通气参数与设定目标的偏差，并对新生儿紧急转运过程中的两种模式进行比较：研究设计：使用 fabian™ HFOi 呼吸机进行的回顾性观察研究：结果：平均气道压力与设定值的中位偏差为 2O。HFOV 期间，压力振幅与设定值相差 2O。HFOV-VG 期间，振荡容积（VThf）与目标值的中位偏差为-0.07 毫升/千克，但在某些情况下，VThf 比目标值低 0.38 毫升/千克。将允许的最大振幅设定为比通常所需的振幅高 10 cmH2O，可改善 VThf 的维持情况。HFOV 和 HFOV-VG 参数相似，只是不含 VG 的 HFOV 时振幅较低。VThf 结论：HFOV 和 HFOV-VG 可将呼吸机参数维持在接近目标值的水平，是新生儿转运过程中很有前途的模式。

期刊介绍： The Journal of Perinatology provides members of the perinatal/neonatal healthcare team with original information pertinent to improving maternal/fetal and neonatal care. We publish peer-reviewed clinical research articles, state-of-the art reviews, comments, quality improvement reports, and letters to the editor. Articles published in the Journal of Perinatology embrace the full scope of the specialty, including clinical, professional, political, administrative and educational aspects. The Journal also explores legal and ethical issues, neonatal technology and product development. The Journal’s audience includes all those that participate in perinatal/neonatal care, including, but not limited to neonatologists, perinatologists, perinatal epidemiologists, pediatricians and pediatric subspecialists, surgeons, neonatal and perinatal nurses, respiratory therapists, pharmacists, social workers, dieticians, speech and hearing experts, other allied health professionals, as well as subspecialists who participate in patient care including radiologists, laboratory medicine and pathologists.
