Manikin-integrated digital measuring system for assessment of infant cardiopulmonary resuscitation techniques

Area of Science:

• Medical Simulation
• Emergency Medicine
• Biomedical Engineering

Background:

• High-quality cardiopulmonary resuscitation (CPR) requires adherence to specific components, with variations for infant CPR techniques like two-thumb or two-finger methods.
• Comprehensive evaluation of infant CPR quality has been challenging due to the lack of suitable objective assessment tools.

Purpose of the Study:

• To develop and validate a novel manikin-integrated, digital measuring system for objective, component-by-component evaluation of infant CPR performance.
• To establish a new evaluation index for quantifying overall infant CPR quality based on previously verified metrics.

Main Methods:

• Development of a manikin-integrated digital system to collect and analyze data on individual CPR components, including hand placement.
• Creation of a new digital scoring system based on a validated evaluation index.
• Validation of the system's feasibility through simulations involving both novice and expert first aid providers.

Main Results:

• The system objectively estimates infant CPR performance by evaluating individual components and providing digital scores.
• Statistically significant differences in performance were observed between beginner and expert groups.
• The system identified specific weaknesses in each group, supporting the development of customized training.

Conclusions:

• The developed digital system offers a valuable tool for objectively assessing infant CPR quality.
• The system's ability to reflect all CPR components in evaluation makes it applicable to general CPR technique assessment.
• Findings support the creation of personalized CPR training strategies based on objective performance data.
