Abstract:
The study assessed the impact of procedural errors on the remote dielectric sensing system (ReDS), a non-invasive lung fluid assessment technology, in an Asian cohort. Healthy volunteers underwent ReDS measurements following manufacturer\'s instructions, with two consecutive measurements one minute apart. A subset of 20 participants had modified procedure settings. Reliability was measured using intraclass correlation coefficient (ICC). The study included 86 healthy volunteers, and all ReDS measurements fell within the recommended normal range. The intra-rater reliability of ReDS measurements was excellent, with an ICC of 0.968. Among the subset of 20 subjects, deviations in height and weight did not significantly affect ReDS values. However, deviations in chest size by ± 3 cm had a noticeable impact on ReDS measures, and incorrect station selection led to fluctuations in ReDS readings. In conclusion, the ReDS system demonstrated excellent intra-rater reliability and applicability in an Asian cohort. Procedural errors, such as chest size measurement and station selection, significantly influenced ReDS measurements. Adherence to standardized operating procedures is crucial to ensure accurate and consistent results. These findings highlight the importance of adherence to manufacturer instructions when utilizing ReDS for lung fluid assessment, thereby enhancing its reliability and clinical applicability.
摘要:
该研究评估了程序错误对遥感系统(ReDS)的影响,非侵入性肺液评估技术,在亚洲队列中。健康志愿者按照制造商的说明进行了ReDS测量,间隔一分钟进行两次连续测量。20名参与者的子集修改了手术设置。使用组内相关系数(ICC)测量可靠性。这项研究包括86名健康志愿者,所有ReDS测量值均在推荐的正常范围内。ReDS测量的内部评估者可靠性非常好,ICC为0.968。在20个受试者的子集中,身高和体重的偏差对ReDS值没有显著影响.然而,胸部大小偏差±3厘米对ReDS测量有明显影响,错误的电台选择导致ReDS读数波动。总之,ReDS系统在亚洲队列中显示了出色的评分者内部可靠性和适用性。程序错误,如胸部尺寸测量和工位选择,显著影响ReDS测量。遵守标准化操作程序对于确保准确和一致的结果至关重要。这些发现强调了在使用ReDS进行肺液评估时遵守制造商说明的重要性,从而提高其可靠性和临床适用性。
