and water applied to the cannula-concentrator connection point and looking for bub-
bles.
IMPORTANT: Flow can be verified by putting the oxygen concentrator in continuous
mode and placing the end of the nasal cannula under the surface of a half full cup of
water and looking for bubbles.

breath rates. In Eco Mode, the device will deliver a fixed volume of oxygen per minute
regardless of breath rate, and will give an extended battery duration.
