Abstract

Background

New devices are now available to provide real-time feedback on ventilation for basic life support providers responding to out-of-hospital cardiac arrest (OHCA). This scoping review, conducted as part of the evidence review for the International Liaison Committee on Resuscitation, aimed to examine the extent of evidence examining ventilation feedback devices and to identify research gaps regarding these devices.

Methods

This scoping review was conducted using Arksey and O’Malley’s framework and reported according to PRISMA-ScR guidelines. Medline, EMBASE and Cochrane were searched from database inception to March 13th, 2025. Studies examining real-time ventilation quality feedback in humans and manikins of any design were included. Ventilation feedback devices were defined as any device that can provide information on the delivery of each insufflation (including insufflation and/or exsufflation measured volume as well as rate) and to guide the ventilation through real-time feedback.

Results

We screened 794 titles, with 17 studies (including 4 conference abstracts) included: one randomised trial (RCT), one before-after prospective studies, two observational studies, one case series and 12 simulation studies. Only three simulation studies assessed a pediatric scenario. The RCT reported improved early outcomes (unadjusted return of spontaneous circulation and 30-hour survival) with real-time feedback, but no difference at hospital discharge. Two observational studies also found no change in patient outcomes, but noted improved ventilation rate and insufflation volumes. Most simulation studies showed improvements in ventilation parameters.

Conclusion

Real-time feedback devices seem to improve ventilations, but we found insufficient evidence of their effect on clinical outcomes to merit a systematic review at this time. Rigorous evaluation of the clinical efficacy and effectiveness of these devices is needed.

实时通气质量反馈装置在院外心脏骤停中的疗效：一项范围综述

新的设备现在可以为应对院外心脏骤停（OHCA）的基本生命支持提供者提供实时的通气反馈。作为国际复苏联络委员会证据审查的一部分，该范围审查旨在审查通风反馈装置的证据程度，并确定有关这些装置的研究差距。方法本综述采用Arksey和O 'Malley框架，并根据PRISMA-ScR指南进行报告。检索自数据库建立至2025年3月13日的Medline、EMBASE和Cochrane数据库。包括对任何设计的人体和人体模型进行实时通风质量反馈的研究。通风反馈装置被定义为能够提供每次充气（包括充气和/或呼气测量量以及速率）的传递信息，并通过实时反馈指导通气的任何装置。结果我们筛选了794个标题，其中17项研究（包括4篇会议摘要）包括：1项随机试验（RCT）、1项前后前瞻性研究、2项观察性研究、1项病例系列研究和12项模拟研究。只有三个模拟研究评估了儿科的情况。RCT报告了实时反馈改善的早期结果（未经调整的自发循环恢复和30小时生存），但出院时没有差异。两项观察性研究也没有发现患者预后的变化，但注意到通气率和充气量的改善。大多数模拟研究显示通风参数有所改善。结论：实时反馈设备似乎改善了通气，但我们没有发现足够的证据表明其对临床结果的影响，因此不值得进行系统评价。需要对这些器械的临床疗效和有效性进行严格的评估。
