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.
Note: Use the demand flow mode at flow settings of 1 to
6 L/min only. At flow settings below 1 L/min, you should use
the continuous flow mode to extend your use time.
Note: With the Companion 550 in the demand flow mode,
you may experience continuous flow from the oxygen outlet
when using the unit immediately after filling. If this is the
case, you should notice normal demand flow operation
within about 10 minutes.
Using the Portable Unit
You may wear the Companion Portable on your right or left side, either
over your shoulder or across your body. An adjustable shoulder strap and
pad provide maximum comfort. In addition, you may engage the plastic
buckle in the shoulder strap to create a short carrying handle.
