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

Vergleich Der Qualität Der Kardiopulmonalen Reanimation Durch Professioneller Helfer (Notärzte / Rettungsassistenten) während Lufttransporten

Investigation of the influence of narrowness and unusual circumstances on the CPR-quality

Study Overview

• Status: Unknown
• Conditions: Cardiac Arrest
• Intervention / Treatment: Other: transport

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The average achieved cardiac output	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.	after 10 minutes

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Now-flow-time	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.	after 10 minutes
