A high quality of chest compressions, e.g. sufficient depth (5-6 cm) and rate (100-120 per min), has been associated with survival. The patient's underlay affects chest compression depth. Depth and rate can be assessed by feedback systems to guide rescuers during cardiopulmonary resuscitation.
The purpose of this study was to describe the quality of chest compressions by healthcare professionals using real-time audiovisual feedback during in-hospital cardiopulmonary resuscitation.
An observational descriptive study was performed including 63 cardiac arrest events with a resuscitation attempt. Data files were recorded by Zoll AED Pro, and reviewed by RescueNet Code Review software. The events were analysed according to depth, rate, quality of chest compressions and underlay.
Across events, 12.7% (median) of the compressions had a depth of 5-6 cm. Compression depth of >6 cm was measured in 70.1% (median). The underlay could be identified from the electronic patient records in 54 events. The median compression depth was 4.5 cm (floor) and 6.7 cm (mattress). Across events, 57.5% (median) of the compressions were performed with a median frequency of 100-120 compressions/min and the most common problem was a compression rate of <100 (median=22.3%).
Chest compression quality was poor according to the feedback system. However, the distribution of compression depth with regard to underlay points towards overestimation of depth when treating patients on a mattress. Audiovisual feedback devices ought to be further developed. Healthcare professionals need to be aware of the strengths and weaknesses of their devices.
高质量的胸外按压，如足够的深度（5 - 6厘米）和频率（每分钟100 - 120次）与患者存活相关。患者的衬垫会影响胸外按压深度。深度和频率可通过反馈系统进行评估，以在心肺复苏期间指导救援人员。
本研究的目的是描述医疗保健专业人员在院内心肺复苏期间使用实时视听反馈进行胸外按压的质量。
进行了一项观察性描述性研究，纳入63例有复苏尝试的心脏骤停事件。数据文件由Zoll AED Pro记录，并由RescueNet代码审查软件进行审查。根据深度、频率、胸外按压质量和衬垫对这些事件进行分析。
在所有事件中，12.7%（中位数）的按压深度为5 - 6厘米。70.1%（中位数）的按压深度测量值大于6厘米。在54例事件中可从电子病历中识别出衬垫情况。按压深度中位数在地板上为4.5厘米，在床垫上为6.7厘米。在所有事件中，57.5%（中位数）的按压频率中位数为每分钟100 - 120次，最常见的问题是按压频率低于100次/分钟（中位数 = 22.3%）。
根据反馈系统，胸外按压质量较差。然而，考虑到衬垫情况的按压深度分布表明，在床垫上治疗患者时深度可能被高估。视听反馈设备应进一步开发。医疗保健专业人员需要了解其设备的优缺点。
