H850 Portable Oxygen Unit Home Use Guide
WARNING
Do not attach an external flow control device that
can be set higher than ten liters per minute (lpm) to
your HELiOS reservoir.
Note:
Do not attach the reservoir oxygen supply line to the
external flow control device.
External Flow Control Device
Use of the external flow control device is based on your
physician’s recommendation. It provides adjustable,
continuous flow direct to a single lumen cannula. If your
physician determines you need an external flow control
device, your oxygen supply company should provide it.
External Flow Control Device with Humidifier Bottle
The external flow control device may also come with a
humidifier bottle. This provides additional humidity to
keep the air you breathe moist. If your physician
recommends it, your oxygen supply company will
supply a humidifier bottle and single-lumen cannula to
use with the reservoir.
