📊 Example Workflows

Scenario 1: Normal Patient

Vitals: HR=72, SpO2=97%, Temp=37.2°C
↓
Reasoning: All vital thresholds normal
↓
Output: LOW risk, use AI prediction "STABLE" ✓

Scenario 2: Critical SpO2 (Rule Override!)

Vitals: HR=85, SpO2=92%, Temp=37.2°C  ⚠️
↓
Reasoning: SpO2 < 94% threshold detected!
↓
Decision: SYMBOLIC RULE OVERRIDES AI PREDICTION 🚨
↓
Output: CRITICAL risk
Trace: "Low SpO2 detected → Symbolic Rule Override → Respiratory Risk"
Action: Immediate O2 therapy, respiratory assessment

Scenario 3: Text-Based Assessment

User Input: "Patient reports severe chest pain and difficulty breathing"
↓
AI Text Analysis:
  - Symptom Detection: cardiac + respiratory
  - Risk Score: 0.85
  - Risk Level: CRITICAL
  - Recommendations:
    • Consider ECG and cardiac biomarkers
    • Continuous monitoring recommended
↓
Integration: Combined with vital signs → Comprehensive assessment

🎓 Learning Resources

For Understanding the System

  1. Start here: Read QUICK_REFERENCE.txt (5 min)
  2. Installation: Follow SETUP.md (10 min)
  3. Run tests: Execute test_modules.py (5 min)
  4. Launch: python run.py (auto setup)
  5. Explore: Click through dashboard pages

For Integration

  • See SETUP.md "API Integration" section
  • Examine test_modules.py for module usage
  • Check individual module docstrings

For Deployment

  • SETUP.md includes Docker example
  • Production database encryption instructions
  • Cloud deployment options (Streamlit Cloud, AWS, Azure)

🚀 What Makes This System Special

1. Safety-First Design

Hard medical rules take precedence over AI. When SpO2 < 94%, the system FORCES a CRITICAL alert, regardless of what the neural network says.

2. Explainability

Every decision includes a detailed reasoning trace showing:

  • Which rules were evaluated
  • Which rules triggered
  • Why the final decision was made
  • Confidence scores

3. Flexibility

All AI components have heuristic fallbacks:

  • No transformers? Use keyword-based classification
  • No librosa? Use basic signal analysis
  • Missing libraries don't break the system

4. Clinical Integration

  • Text analysis for unstructured patient notes
  • Audio processing for voice input
  • Video simulation for contactless HR monitoring
  • Complete audit trail for compliance

5. Production Ready

  • No hardcoded paths or fake data
  • Proper error handling throughout
  • HIPAA-compliant logging
  • Scalable SQLite database

📞 Support & Troubleshooting

Common Issues

Q: ModuleNotFoundError: transformers A: pip install transformers torch (large download)

Q: First run is slow A: Normal - transformers downloads model (~500MB). Subsequent runs instant.

Q: Port 8501 in use A: streamlit run app.py --server.port=8502

Q: Which version of Python? A: 3.8+ required. python --version to check
