Enterprise AI Analysis: Applied Computing Review
Human Injury Severity Assessment for Outdoor Emergency Rescue Based on Wearable Photoplethysmogram Devices
This research pioneers a novel approach to Human Injury Severity (HIS) assessment for outdoor emergency rescue, leveraging wearable Photoplethysmogram (PPG) devices. By integrating PPG-derived physiological data with advanced machine learning models, the study addresses the critical need for real-time, non-invasive injury detection in challenging environments. The findings demonstrate the high potential for specific AI models, such as CatBoost for mild injuries and RBF_SVM for moderate to severe cases, to significantly enhance emergency response capabilities. This technology offers a pathway to proactive distress signaling and improved on-field triage, moving beyond traditional bulky medical equipment.

Human Injury Assessment Results
| Scoring Standard | PPG Measurable Indicators | Applicability |
|---|---|---|
| NEWS (National Early Warning Score) | Heart Rate, Respiratory Rate, SpO2, Blood Pressure | Highly feasible, covers critical vital signs. |
| MEWS (Modified Early Warning Score) | Heart Rate, SpO2, Blood Pressure | Highly feasible, covers critical vital signs. |
| RTS (Revised Trauma Score) | Heart Rate, Blood Pressure (Systolic) | Feasible, covers core vital signs; GCS score needs external input/PRV for proxy. |
| APACHE II (Acute Physiology And Chronic Health Evaluation score-II) | Heart Rate, Oxygenation Index (SpO2), Blood Pressure (Mean Arterial) | Feasible, covers key physiological components. Other APACHE factors need external input. |
0.9845
CatBoost AUC for Mild Injuries
The CatBoost model demonstrated an exceptional Area Under the Curve (AUC) of 0.9845 for mild injury cases, indicating its superior ability to accurately distinguish mild patients from non-mild patients. This is crucial for early intervention.
Real-time Field Triage with Wearable AI
Scenario: Imagine an outdoor adventurer injured in a remote location, unable to communicate. A wearable PPG device, continuously monitoring physiological data, detects a sudden drop in SpO2 and irregular heart rate, indicative of a moderate injury.
Solution: The device's integrated CatBoost/RBF_SVM AI model instantly processes this data, classifies the injury severity as 'moderate,' and automatically dispatches a distress signal with precise GPS coordinates to a rescue team. This proactive alert bypasses manual reporting, significantly reducing response time.
Outcome: Rescue personnel arrive much faster, equipped with prior knowledge of the injury's severity, enabling immediate and appropriate medical intervention. This not only improves patient outcomes but also optimizes resource allocation for the rescue operation.
Highlight: The ability to proactively and accurately assess injury severity in real-time in challenging outdoor scenarios represents a significant leap forward in emergency response, saving critical time and lives.
