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.
This unit is not to be used for life support. Geriatric, pediatric, or any other patient unable to communicate discomfort while
using this device may require additional monitoring. Patients with hearing and/or sight impairment(s) may need assistance
with monitoring alarms.
Pulse Dose Node settings must be determined for each patient individually for their needs at rest, during exercise, and
when traveling.
If you feel discomfort or are experiencing a medical emergency, seek medical assistance immediately.
In the event of an alarm or you observe FreeStyle is not working properly; consult the Troubleshooting section in this
manual. If you cannot resolve the problem, consult your Equipment Provider.
o Start-Up
A brief alarm sounds at start-up. FreeStyle begins to operate when the alarm stops.
o Low Battery
As the battery power approaches a low level, a brief alarm sounds intermittently, and the yellow 25% Battery gauge /
indicator (Figure 11) light also illuminates intermittently. When this occurs, connect FreeStyle to a DC power outlet or to
an AC power outlet, or change to another source of oxygen within two minutes. When FreeStyle is connected to DC
power outlet or AC power outlet, the unit operates while recharging FreeStyle’s battery simultaneously. The level of
battery charge is indicated by the battery gauge/indicator(s).
