6.3 USING THE NASAL CANNULA
CAUTION!
Risk of minor injury or discomfort
The proper placement and positioning of the prongs of the nasal cannula in the nose is critical for oxygen to
be delivered. Make sure the nasal cannula is properly connected to the nozzle fitting and that the tubing is not
kinked or pinched in any way. Replace the nasal cannula on a regular basis.
WARNING!
Risk of injury
Nasal cannula should be rated for 6 liters per minute to ensure proper oxygen delivery. Note that cannulas may
be rated in "liters per minute" even though your prescribed pulse dose setting number does not represent a
constant flow in liters per minute.
A nasal cannula must be used with the device to provide oxygen from the concentrator. A
single lumen cannula up to 25 feet in length is recommended to ensure proper breath detec-
tion and oxygen delivery. Reference manufacturer's instructions for use.
6.4 AC POWER SUPPLY (BA-502/BA-501)
The AC power supply includes an AC power supply that connects to the device and an AC power cable to connect
to the power supply and corresponding AC outlet. The AC power supply will automatically adapt to input voltages
from 100V-240V (50-60Hz).
To use AC power, do the following:
1. Connect the AC power brick to the power supply cable.
2. Plug the power supply cable into a standard wall outlet.
3. Insert the power supply cable into the power port located near
the particle filter on the back of the concentrator.
The AC power supply will charge the batteries when the device is
plugged into AC power (except on airplanes).
