MultiCPR: The Influence of Firefighter's PPE on Chest Compressions (MultiCPR3)

The aim of this clinical study is to evaluate the impact of wearing firefighters' personal protective equipment (PPE) on the quality of chest compressions during simulated resuscitation scenarios. The study compares the effects of one-minute versus two-minute intervals for switching the individual performing compressions.

How does the clinical trial work? This randomized cross over trial will be conducted in several locations and will involve a total of 38 fire-fighters. The study will be conducted by the Department of Anesthesiology of the Medical University of Vienna.

Participation in this clinical study is expected to last 30 minutes in total. Participants are randomized to either one or two minute intervalls of performing chest compressions in teams of two. After a cooling-of phase of at least 24 hours, they will be switched to the other group.

Chest compressions will be performed for 12 minutes in full firefighter's PPE. Primary outcome will be chest compression depth.

Treatment and study plan

Chest compressions

Procedure

Performing chest compressions in full firefighter's personal protcetion equipment

One minute rotation intervall

Procedure

Chest compressions using a one minute rotation intervall

Two minute rotation intervall

Procedure

Chest compressions using a two minute rotation intervall

Primary outcomes

  1. Chest Compressions depth

    Time frame: during 12 minutes of chest compressions. 2x12 = 24minutes in total per participant

    depth in milimeter

Secondary outcomes

  1. Chest compression rate

    Time frame: during 12 minutes of chest compressions. 2x12 = 24minutes in total per participant

  2. Incomplete recoil (leaning) during chest compressions

    Time frame: during 12 minutes of chest compressions. 2x12 = 24minutes in total per participant

    Incomplete recoil is an important measure during chest compressions as it impairs ventricular filling. Incomplete recoil is measured in milimeters.
