Utility description: Patient Hypoxia Risk During Xe Breathing Checker

Patient Hypoxia Risk During Xe Breathing Checker — Patient Hypoxia Risk Analyzer during Xenon Inhalation

ℹ️  Utility evaluates patient safety during xenon inhalation:
    • Minimum SpO2 level
    • Inspired oxygen concentration (FiO2)
    • Desaturation depth
    • Recovery time

⚠️  CRITICAL: Xenon displaces oxygen from alveoli!
    Even short-term hypoxia can be dangerous for COPD patients.

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

Input format:

Example:
  XE-HYPOXIA-2026-001,HP-Xe-129,21.0,79.0,98.0,14.5,92.0,95.0,15,90.0,94.0

— WHY IS THIS NEEDED?
Hypoxia control is critical for HP-MRI procedure safety:
• Inhaling pure xenon gas mixture (without added O2) causes sharp drop in oxygen partial pressure
• This leads to rapid decrease in saturation (SpO2)
• For patients with lung pathologies (COPD, fibrosis), even short hypoxia can be fatal
• Utility helps assess risk before procedure and monitor it during inhalation

⚠️  CRITICAL:
• SpO2 must not drop below 90% (critical threshold)
• Using oxygen-enriched mixture (e.g., 30% O2 / 70% Xe) is significantly safer
• Desaturation depth should not exceed 5% from baseline
• Saturation recovery time must be minimal (<60 sec)

Key features:
• Risk assessment based on patient physiological parameters
• Inspired mixture composition control
• Hypoxic episode depth and duration calculation
• Recovery time prediction

Critical parameters:
• Min SpO2: ≥90%
• FiO2: ≥21%
• Desaturation Depth: ≤5%
• Recovery Time: <60 sec

💡 Usage tips:
1. Always measure baseline SpO2 before procedure
2. Use pulse oximeter with fast response time
3. For patients with low baseline saturation, necessarily use oxygen-enriched mixture
4. Limit breath-hold time to 15-20 seconds
5. Have 100% oxygen mask ready for emergency desaturation

⚠️ Note: Unlike standard MRI where patient breathes air, here they inhale inert gas which physically prevents body from receiving oxygen at that moment. The utility turns this physiological fact into a manageable safety parameter.
