Compression Is Life In Cardiac Arrest - Quality Study (CILICA-QS)

Study Overview
=================
Brief Summary
-----------------
Context: Chest compressions quality is known to be essential in cardiopulmonary resuscitation. Despite a known harmful effect of chest compressions interruptions, current guidelines still recommend provider switch every 2 minutes. Feedback impact on chest compressions quality preservation during cardiopulmonary resuscitation remains to be assessed. Study design: simulated prospective monocentric randomized crossover trial. Participants and methods: Sixty five professionals rescuers of the pre-hospital care unit of University Hospital of Caen (doctors, nurses and ambulance drivers) are enrolled to performed continuous chest compression on manikin (ResusciAnne®, Laerdal), twice, with and without a feedback device (CPRmeter®). Correct compression score (the main criterion) is defined by reached target of rate, depth and leaning at the same time (recorded continuously). Hypothesis: Feedback device preserve chest compression quality above the 2 minutes recommended switch over during cardiopulmonary resuscitation.

Design Details

Primary Purpose: Other
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: In Guide group, participants have a real time feedback (and record) on chest compression quality performed by means of the visuals informations profided by the feedback device. In Blind group, participants have a real time record of chest compression quality performed by means of the feedback device without feedback information of the performance.
Masking: None (Open Label)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correct compression score | Correct compression score is defined by reached target of rate (between 100/min and 120/min), depth (between 50 mm and 60 mm) and leaning (less than 2500g) at the same time | Day 0 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Decrease time of 30% of correct compression score | Time at witch correct compression score decrease of 30% of the reference correct compression score (first 20 secondes) | Day 0 | 
| Chest compression depth | Chest compression depth reached (in mm) | Day 0 | 
| Chest compression rate | Chest compression rate per min | Day 0 | 
| Percentage of chest compression without leaning | Percentage of chest compression without leaning defined with a residual weight egal or above 2500 g | Day 0 | 
| Percentage of chest compression with correct depth | Percentage of chest compression with depth between 50 mm and 60 mm | Day 0 | 
| Percentage of correct chest compression rate | Percentage chest compression rate between 100/min and 120/min | Day 0 | 
| Participants' fatigue (Borg's scale) | Participant auto-evaluation of fatigue with a predefined scale from 6 to 20 (no unit). | Day 0 |
