It is very important to select only the prescribed level of oxygen.
Change the pulse flow selection only under the guidance of your
physician.
Alarm/Light Indicators
When the FreeStyle unit senses inhalation, a pulse of oxygen is sent through the
nasal cannula. The green light above the selected pulse flow setting displays
intermittently each time a breath is detected.
Additionally, when the unit is operating on and simultaneously being charged
through the Universal AC/DC power supply, the FreeStyle unit’s battery
gauge/indicator(s) display the charge level of the battery and remain on for
approximately one hour after reaching a full charge.
An audible alarm sounds if FreeStyle has a low battery, if the cannula is
disconnected, or if performance of the unit is outside specifications. The light and
audible alarm conditions are explained in detail below and summarized on the
chart later in this section of the manual.
