FEATURES
Ⅰ. SUMMARY
The oxygen concentrator is intended for individual use in the professional healthcare
facility and home healthcare environment. It is an electronically operated device that
separates oxygen from room air. It provides high concentration of oxygen directly to
you through a nasal cannula. Clinical studies have documented that oxygen
concentrators are therapeutically equivalent to other types of oxygen delivery systems.
This user’s manual will tell you about your concentrator and will serve as a reference
as you use your concentrator.
Ⅱ. CHARACTERS
