Comparison of the Quality of CPR by Lay Rescuers With and Without Feedback Devices

Comparison of the Quality of CPR by Lay Rescuers With and Without Telephone Instructions by a Simulated Rescue Coordination Center

Comparison of various methods to improve the quality of CPR

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.
