Comparison of the Quality of CPR by Professional Helpers (Emergency Physicians / Paramedics) During Flights

Not Applicable

• Conditions: Cardiac Arrest
• Interventions: Other: transport

• Registration Number: NCT02002481
• Lead Sponsor: University Hospital of Cologne

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.

Arm && Interventions

Group	Intervention	Description
Transport	transport	10 minutes ALS-CPR during a transport

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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.
