2. Alarmed Oxygen 

Monitor / Analyzer 

inaccurate

3. Low flow bleed 

obstructed

4. Gas supply

heliox concentration 

incorrect

5. Downstream device 

causing back flow 

or restricted flow

6. Supply pressure 

imbalanced

1. Use auxiliary outlet &

Oxygen Monitor / 

Analyzer

3. Remove obstruction
