Objectives: Abstract
Effective chest compression performance during cardiopulmonary resuscitation (CPR)
training is crucial for improving survival rates. The conventional methods using mechanical
task trainer may lack real-time feedback and immersive engagement. We designed the
novel training tool, CPR-CHAMPS, on Microsoft HoloLens platform. With the technology
of augmented reality, we designed the overlaying holographic images onto the user’s
real-world surroundings, providing a realistic and immersive experience. By using spatial
Mapping method, CPR-CHAMPS can provide real-time monitoring of chest compression
performance. This study aimed to compare the performance of CPR-CHAMPS with
conventional manikin task trainer (Laerdal Skill Reporter QCPR device) as the novel chest
compression performance monitoring tool.
Methods: A comparative study was conducted in basic life support (BLS) training courses.
Participants used both the CPR-CHAMPS and Laerdal QCPR (L-QCPR) devices while
performing CPR on a Resusci Anne manikin. This allowed a direct comparison of the
two systems’ ability to assess CPR quality. Key metrics included average compression
depth, compression rate, and the percentage of compressions meeting American Heart
Association (AHA) guidelines. Qualitative feedback was collected via post-training
questionnaires. Inter-rater reliability was analyzed using Intraclass Correlation Coefficients
(ICCs) with a two-way mixed-effects model.
Results: A total of 65 participants were enrolled, including medical students (n = 56, 86%) and high
school students (n = 9, 14% ). Inter-rater reliability analysis showed statistically significant
agreement (p < .001 for most measures) between CPR-CHAMPS and L- QCPR. For
average compression depth, ICC indicated good agreement (0.704, 95% CI: 0.497-0.823),
while agreement for compressions meeting depth guidelines was moderate (ICC = 0.556,
95% CI: 0.273-0.729). Average compression rate showed good reliability (ICC = 0.807, 95%
CI: 0.401-0.915), while the percentage of compressions meeting rate guidelines showed fair
agreement (ICC = 0.397, 95% CI: -0.044-0.648). Qualitative feedback highlighted benefits
such as realistic scenarios and real-time feedback but also noted issues with user comfort,
interface complexity, and depth tracking inconsistencies.
