GasMixingRatioAndHypoxiaRiskChecker

Utility description: Gas Mixing Ratio & Hypoxia Risk Checker

Gas Mixing Ratio & Hypoxia Risk Checker — Gas Mixing Ratio and Hypoxia Risk Analyzer

ℹ️  Utility controls breathing mixture safety:
    • Oxygen level (≥19-21%)
    • Xenon level (≤30% for conscious patients)
    • Gas balance (100%)
    • Hypoxia risk index

⚠️  CRITICAL: Xenon displaces oxygen!
    Incorrect mixture leads to rapid loss of consciousness or hypoxia.

Usage:
  GasMixingRatioAndHypoxiaRiskChecker.exe                            → demo mode (console output)
  GasMixingRatioAndHypoxiaRiskChecker.exe input.csv output.json      → evaluate your data

Input format:
BatchNumber,ProductName,Xe_Conc_Percent,O2_Conc_Percent,N2_Conc_Percent,Min_O2_Level,Max_Xe_Level

Example:
  XE-MIX-2026-001,HP-Xe-129 Mix,25.0,21.0,54.0,19.0,30.0

— WHY IS THIS NEEDED?
Gas mixture control is critical for patient safety in HP-MRI:
• Xenon is an inert gas but acts as an anesthetic at high concentrations
• Adding xenon to breathing mixture proportionally reduces oxygen share
• If O2 level drops below 19%, tissue hypoxia risk occurs
• If Xe level exceeds 30-35%, patient may lose consciousness directly in scanner
• Nitrogen (N2) is used as buffer gas to balance pressure and concentration

⚠️  CRITICAL:
• Oxygen ≥19-21% — mandatory condition for breathing without support
• Xenon ≤30% — limit for maintaining consciousness in adult patient
• Sum of all gases must equal 100% (gas analyzer integrity check)
• Automatic gas delivery lockout upon parameter deviation

Key features:
• Real-time hypoxia risk index calculation
• Xenon anesthetic threshold control
• Gas analyzer data integrity check (Mass Balance)
• Support for various mixing protocols (binary and ternary mixtures)

Critical parameters:
• O2 Level: ≥19%
• Xe Level: ≤30%
• Total Sum: 100% ± 1%
• Hypoxia Risk Score: < 5

💡 Usage tips:
1. Use certified medical gas analyzers
2. Calibrate oxygen sensors before each working day
3. Configure emergency alarm for O2 drop below 19%
4. Account for patient's physiological oxygen consumption when calculating session duration
5. For patients with pulmonary diseases, increase minimum O2 threshold to 23-25%

⚠️ Note: Unlike standard drugs where dose is measured in milligrams, here dose is percentage content in each breath. Mixer error of even 1-2% can have fatal consequences within minutes. The utility ensures continuous monitoring of this balance.
