Objective The International Liaison Committee on Resuscitation has recommended improvements in training for neonatal resuscitation, highlighting the potential role of respiratory function monitors (RFMs). Our objective was to determine whether a manikin-based, standardised face mask ventilation training intervention using an RFM with a simple visual display reduced face mask leak. Design Multicentre, before and after study. Participants and instructors were blinded to the RFM display during both assessment periods. Participants Healthcare professionals working or training in a hospital providing maternity and neonatal services. Intervention All participants underwent a training intervention on positive pressure ventilation using a modified, leak-free manikin and RFM. The intervention consisted of a demonstration of optimal face mask ventilation technique, training in RFM interpretation with corrective strategies for common scenarios and a period of deliberate practice. Each participant performed 30 s of positive pressure ventilation blinded to the RFM display before and after training. Main outcome measures The primary outcome was face mask leak (%) measured after training. Secondary outcome measures included expired tidal volume, inflating pressures and ventilation rate. Adjustments made to technique during training were an important qualitative outcome. Results Four hundred and fourteen participants were recruited over a 13-month period from April 2022, and 412 underwent analysis. Median (IQR) face mask leak before training was 31% (10–69%) compared with 10% (6–18%) after training (p<0.0001). Improvements were noted across all other ventilation parameters. Conclusion Standardised face mask ventilation training using an RFM with simple visual feedback led to a significant reduction in leak. All data relevant to the study are included in the article or uploaded as supplemental information.

使用标准化干预和呼吸功能监测仪进行新生儿面罩通气训练：人体模型前后研究

目标 国际复苏联络委员会建议改进新生儿复苏培训，强调呼吸功能监测仪 (RFM) 的潜在作用。我们的目标是确定使用带有简单视觉显示器的 RFM 的基于人体模型的标准化面罩通气训练干预是否可以减少面罩泄漏。设计多中心，研究之前和之后。在两个评估期间，参与者和讲师均无法看到 RFM 显示。参与者 在提供孕产妇和新生儿服务的医院工作或接受培训的医疗保健专业人员。干预 所有参与者均使用改良的无泄漏人体模型和 RFM 接受正压通气培训干预。干预措施包括最佳面罩通气技术的演示、RFM 解释培训以及针对常见情况的纠正策略以及一段时间的刻意练习。每个参与者在训练前后均进行 30 秒的正压通气，且不查看 RFM 显示。主要结果指标 主要结果是训练后测量的面罩泄漏率 (%)。次要结果指标包括呼气潮气量、充气压力和通气率。训练期间对技术进行的调整是一个重要的定性结果。结果 自 2022 年 4 月起的 13 个月内招募了 414 名参与者，其中 412 人接受了分析。训练前面罩泄漏中位数 (IQR) 为 31% (10–69%)，而训练后为 10% (6–18%) (p<0.0001)。所有其他通气参数均得到改善。结论 使用带有简单视觉反馈的 RFM 进行标准化面罩通气训练可显着减少漏气。与研究相关的所有数据都包含在文章中或作为补充信息上传。
