Introduction
Early bystander cardiopulmonary resuscitation (CPR) improves outcomes after cardiac arrest. (1-3) CPR quality might be improved by feeding back to rescuers during resuscitation efforts. (4) Brayden Illuminating CPR Manikin employs LED lights to offer real-time compression rate and depth feedback to candidates during CPR delivery. This study aimed to understand users’ opinions toward the Brayden model compared with the industry leader.

Materials & Methods
This qualitative study was conducted during basic life support courses at The University of Birmingham, between October 2017 and April 2018). Feedback was collected from candidates and instructors exploring usability (e.g. ability to correct speed of compressions) and reliability (e.g. incidence of manikin malfunction). A 10 point Likert scale was also used to record candidate enjoyment and confidence in CPR performance. 

Results
Overall 188 candidate and 6 instructor responses were collected. Candidates reported finding the Brayden model  more realistic (40% vs. 20%) and easier to use (53% vs. 46%), when compared to the to Laederal model respectively. Approximately half of candidates using the Brayden model reported it ‘easier’ to achieve correct rate (47%) and depth (51%). 28% of candidates reported initial confusion regarding the significance of the illumination feedback, however 58% reported good understanding by the end of the course. 66% of instructors reported illumination useful when teaching.  
Students said: “The lights were very useful- reinforced compression depth & rate”, “Very good idea”, “Feel the new manikin is helpful for those doing it the first time but is not as helpful for those who have done a similar course before…”.

Conclusion
Overall some candidates found the Brayden Illuminating CPR Manikin useful and enjoyable to use. Initial confusion regarding the significance of the illumination feedback could be reduced with specific briefing prior to use, providing context to the illumination, ensuring students fully understand its significance and derive the most benefit.
