Setting of the Flow Selector for Prescribed Oxygen Concentration
The FreeStyle unit has three pulse flow settings: 1, 2, and 3, providing flows equivalent to 1–3 LPM oxygen. Lift the dust
cover on the unit's keypad, and press the 1, 2, or 3 button, which corresponds to the oxygen pulse flow that your physician
has prescribed. (See Figures 13 and 14.)

It is very important to select only the prescribed level of oxygen flow. Change the pulse flow selection only
under the guidance of your physician.
