Cardiac Arrest
Conditions
Brief summary
Investigation of the influence of narrowness and unusual circumstances on the CPR-quality
Detailed description
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 under normal ambient conditions. Especially the mean frequenices of cardiac compression varies from 60 to 160/min, as well as the now-flow-time. Aim of this study is to investigate how narrowness and movement during a transport affect the CPR-performance. For this, we examine the impact of the common transport options (air and ground) on the outcome-varity on a manikin. The subjects for this study are professional rescuers (emergency physicians / paramedics) who perform a 10 minute ALS-CPR in either normal circumstances (resuscitation-room) or during transportation.
Interventions
OTHERtransport
The manikin will be resuscitated during a transport in a vessel by a professional team (emergency physician / paramedic).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The average achieved cardiac output | after 10 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 10 min manikin-resuscitation. The thus obtained average cardiac-output (CO = CR x CD), measured in \[mm/min\], will be compared in each group. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Now-flow-time | after 10 minutes | Second objective of the study is the time without chest-compression during the 10 minutes ALS-CPR. The now-flow-time is read out of the recorded manikin-data specify, in \[min\] and \[sec\]. As a result, the average now-flow-time in each group will be calculated and compared for each group. |
