Candidate Passive Sensor Suite Technologies for Tactical Combat Casualty Care Environments: Comparative Assessment...

Area of Science:

• Medical Technology
• Biomedical Engineering
• Military Medicine

Background:

• Analysis of 3 prototype sensor suites for passive documentation of care delivery in tactical combat casualty care environments.
• Developed by the United States Army Institute for Surgical Research.

Purpose of the Study:

• To ensure sensor suites remain resilient and adaptive in complex battlefield environments.
• To conduct a systematic comparative assessment of prototype solutions.

Main Methods:

• A three-phase assessment methodology: tabletop evaluations, simulated use testing, and a sensor suite rodeo simulation event.
• Prioritized functionality, usability, and performance, including human participants in hyperrealistic simulation environments.
• Assessed prototype performance under various operational lighting conditions.

Main Results:

• Tabletop evaluations showed acceptable technical specifications, with simpler configurations scoring higher in data capture and export.
• Simulated use testing and rodeo events indicated passing quantitative scores for usability, with more complex configurations scoring higher.
• Qualitative findings revealed issues with vital sign monitor latency, data transfer of large files, and pairing, with only one camera producing viable video in all lighting conditions.

Conclusions:

• Opportunities exist to combine prototype strengths for a next-generation implementation.
• Limitations include tracking medical supplies, advancing AI for data processing, and managing multiple casualties.
• Follow-on evaluations are needed; the study provides a reproducible framework for advancing battlefield medical technologies.
