CPR Feedback Devices

Study Overview
=================
Brief Summary
-----------------
The aim of the study was to compare two methods of training in CPR, standard basic life support and CPR using CPR feedback device.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Traditional learning<br>chest compression group learning without CPR feedback device. After a month of quality control of chest compressions is made also without the device. | Device: Standard BLS<br>* basic life support without any feedback device<br>|
| Experimental: Experimental learning<br>Training is done using TrueCPR feedback device. After a month of quality control of chest compressions is made without the device. To do this will be indicated on the impact of the use of feedback devices for improving the effectiveness of training in CPR. | Device: Standard BLS<br>* basic life support without any feedback device<br>Device: TrueCPR<br>* CPR with feedback device<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effective compressions compression with correct depth (40-50mm), correct hand position and complete decompressions | effective compressions was defined as compression with correct depth (40-50mm), correct hand position and complete decompressions | 1 month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| effective compressions ratio effective compressions [%] multiplied by flow time [%] | effective compressions ratio was defined as effective compressions [%] multiplied by flow time [%] | 1 month | 
| Flow time sum of all periods during which chest compressions were performed. | flow time was defined as the sum of all periods during which chest compressions were performed. | 1 month | 
| absolute hands-off time sum of all periods without chest compressions or ventilation | absolute hands-off time (HOT) was defined as the sum of all periods without chest compressions or ventilation | 1 month | 
| Compression depth compression in correct depth (40-50mm) measured by the software is connected to the manikin and computer | compression in correct depth (40-50mm) measured by the software is connected to the manikin and computer | 1 month |
