Clues to Hypoxia

• Symptoms vary from person to person
  • Try to take a ride in an altitude chamber
• Slowed mentation
  • subtract compass headings
• Physical symptoms
  • Fatigue, lassitude, dizziness, nausea, headache, dyspnea (sob), and so on
• Look at your equipment!
  • Pressure level, flow indicator, tubing intact, etc.
• Until the "conscious" switch goes "off," there is very little warning.
