5. Select the flow setting 1, 2 or 3 as prescribed
by your doctor. These settings are equivalent
to 1, 2 or 3 LPM settings on a continuous
flow device. Place the nasal cannula in the
nasal passages and breathe normally. When
the LifeChoice POC senses inhalation,
oxygen is supplied through the cannula.
The duration of this pulse flow and size of
the pulse is dependent upon the pulse flow
setting (1, 2, or 3) selected. The green LED
light above the selected number (1, 2, or 3)
illuminates and will flash each time
inhalation is detected indicating that a pulse
of oxygen has been delivered.
6. Check to make sure your unit’s battery is fully
charged (minimum of 4 hours charge time for fully
depleted battery) before venturing out with
LifeChoice POC for the first time or upon
subsequent use. To accurately measure the
internal battery charge the unit must be
powered “on” and disconnected from the
AC/DC power supply or external battery.
The battery gauge/indicator LED lights next
to the Battery Check will illuminate to
indicate the level of battery charge
(25% to
100%). The battery charge indicator LED
lights are a reference only. If a fully depleted
internal battery is not charged for a minimum
of 4 hours, it will not supply 2+ hours of use.
If not charged for the correct amount of time,
a 100% battery charge indicator LED light
may be illuminated, but the actual charge
could be less than 100%.
7. To turn the LifeChoice POC off, press Power
and hold for 2 seconds until the green LED
light above Power goes out and the unit shuts
off. When the LifeChoice POC is powered
off, the internal fans will continue to operate
for approximately 30-45 seconds for additional
cooling.
