简要总结
Comparison of various methods to improve the quality of CPR
详细描述
Even for paramedics and emergency physicians, the resuscitation of patients with cardiac arrest remains a challenge. Previous studies have shown that the cardiac output varies widely even among professional helpers. This is especially due to some very different mean frequencies of cardiac compression wich vary from 60 to 160/min for paramedics. Aim of this study is to investigate whether the use of feedback-devices during cardiac-pulmonary resuscitation (CPR) can lead to an improvement of the cardiac output and may improve survival.
For this, we examine the impact of different feedback-methods on the frequence-variety on manikin by lay rescuers. Overall, we compare three different devices for feedback during CPR. The subjects for this study are lay rescuers who perform a 5 minute chest-compression-only CPR.

结局指标
主要结局
The average achieved cardiac output
时间窗: after 5 minutes
The main goal of the study is the average achieved cardiac output. Data acquisition is carried out on a resuscitation-manikin which can measure compression-rate (CR) and compression-depth (CD). The data are recorded by a computer during the CPR. To calculate the cardiac output, we multiply the average CR \[1/min\] with the average CD \[mm\] during the 5 min manikin-resuscitation. The thus obtained average cardiac-output (CO = CR x CD), measured in \[mm/min\], will be compared in each group.
次要结局
- Constancy of the quality of chest-compressions(after 5 minutes)
