Utility description: Xe-O2 Mixture Safety Blender QC

Xe-O2 Mixture Safety Blender QC — Xe/O2 Safety Blender Quality Control

ℹ️  Utility checks medical gas blender accuracy:
    • O2 and Xe flow errors
    • Output oxygen concentration (safety)
    • Mixing ratio accuracy

⚠️  CRITICAL: Blender is the last line of defense against hypoxia!
    Any error in O2 dosing can cost a patient their life.

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

Input format:
BatchNumber,ProductName,Target_O2_Flow,Measured_O2_Flow,Target_Xe_Flow,Measured_Xe_Flow,Output_O2_Percent,Min_Safe_O2,Max_Flow_Error

Example:
  BLEND-QC-2026-001,Blender v2,0.5,0.51,1.5,1.48,20.5,19.0,5.0

— WHY IS THIS NEEDED?
Blender control is critical for HP-MRI procedure safety:
• Blender combines pure xenon and medical oxygen in safe proportion
• Failure of flow meters (MFC) or valves can lead to delivery of pure xenon (asphyxia)
• Mixing accuracy affects predictability of polarization level (T1)
• Regular blender verification is required by GMP and FDA protocols
• Utility helps detect calibration drift before it becomes dangerous

⚠️  CRITICAL:
• Flow error for each gas ≤5%
• Output oxygen concentration strictly ≥19% (or higher per protocol)
• Mixing ratio must match recipe with high precision
• Automatic lockout upon detection of hazardous deviations

Key features:
• Comparison of target and actual gas flows
• Absolute safety control of output O2 concentration
• Mixing ratio error calculation
• Support for various medical blender models

Critical parameters:
• Flow Error: ≤5%
• Output O2: ≥19%
• Mixing Ratio Error: ≤5%

💡 Usage tips:
1. Perform test runs with nitrogen before using expensive xenon
2. Use independent gas analyzer to check blender output
3. Calibrate flow meters at least once a month
4. Monitor inlet pressure drops as they affect MFC accuracy
5. Maintain calibration log for safety audit

⚠️ Note: Unlike standard dosing equipment, here error is measured not in milliliters but in risk to life. The utility provides dual control: engineering (flow accuracy) and clinical (breathing safety).
