Using the Portable Unit

The Companion Portable unit may be worn on either side of the body. The
unit may be worn over the shoulder or in an across the body fashion. An
adjustable shoulder strap and pad are provided for maximum comfort.
The plastic connector in the shoulder strap may be engaged to create a
short carrying handle.
For Companion 550 only
When using the Companion 550 in the demand flow mode, oxygen is
delivered when the unit senses the user's inspiratory effort. An initial
"puff" of oxygen may be noticed followed by oxygen flow during the
remainder of the inspiration. No oxygen flow occurs during the exhalation
phase of breathing. When the unit is set for the continuous flow mode,
oxygen flows during the entire breathing cycle.
At flow settings of 1 to 6 L/min, the demand flow mode can significantly
increase the planned use time while reducing the drying effect that
continuous flow oxygen has on the nasal passages.
