The aim of this study was to compare four different CPR feedback devices to standard BLS in terms of the quality of single rescuer pediatric resuscitation. Therefore, the investigators hypothesis was that there would be no difference between CPR methods in terms of chest compression quality parameters.
Cardiac arrest is a leading cause of death worldwide. High-quality chest compressions are of paramount importance for survival and good neurological outcome. Unfortunately, even health professionals have difficulty performing effective CPR. Chest compression (CC) is often too shallow, compression ratio is inadequate, and hands-off time is too long. CPR feedback devices might be an option for rescuers to in order to increase CC efficiency.

RECRUITINGEffective compressions
Effective compressions was defined as compression with correct depth (40-50mm), correct hand position and complete decompressions
Time frame: 1 day
Chest compression depth
To measure chest compression depth during 8 minutes. Chest compression depth will be measured using the software connected to the manikin and computer
Time frame: 1 day
Chest compression rate
To measure the chest compression rate during 8 minutes. Chest compression rate will be measured using the software connected to the manikin and computer
Time frame: 1 day
effective compressions ratio
effective compressions ratio was defined as effective compressions \[%\] multiplied by flow time \[%\]
Time frame: 1day
Flow time was defined as the 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.
Time frame: 1 day
absolute hands-off time
absolute hands-off time (HOT) was defined as the sum of all periods without chest compressions or ventilation
Time frame: 1 day
VAS (visual analogue scale)
after having completed the 8 min testing period, the study participants were asked how challenging they had experienced standard BLS or resuscitation which the respective feedback device. answers were rated on a 10-point Lickert scale (most difficult = 1 to easiest = 10)
