Dual Lumen Cannula
In order to breathe from your H300 or H850, you
must do so through a dual lumen nasal cannula.
This type of cannula has two connections to the
portable unit. One connection is used to detect
when you inhale, and the other connection is used
to deliver oxygen to your nose.
A single lumen cannula cannot be used on the
H300/H850. Your breath through the cannula
provides the force necessary to open the flow
control valve and deliver oxygen. You must use a
dual lumen cannula and inhale through your nose
on ALL flow settings to ensure that oxygen is
properly delivered.
Note: Oxygen will only be delivered through the top
cannula barb.
Dual lumen nasal cannula operation: Oxygen is delivered through
top port. Breath is detected through bottom port.
Note: To Equipment Provider: The following oxygen
administration accessories are recommended for
use with the HELiOS:
• Nasal Cannula: CAIRE Part Number 6-778057-00
• Firebreak: CAIRE Part Number 21126636
A firebreak is recommended for use with any
cannula.
• CAIRE offers a firebreak intended to be used in
conjunction with the oxygen portable. The firebreak
is a thermal fuse to stop the flow of gas in the
event that the downstream cannula or oxygen tub-
ing is ignited and burns to the firebreak. It is placed
in-line with the nasal cannula or oxygen tubing
between the patient and the oxygen outlet of the
HELiOS. For proper use of the firebreak, always refer
to the manufacturer's instructions (included with
each firebreak kit).
• For any additional recommended accessories,
please see the Accessories Catalog (PN ML-
LOX0010) available on www.caireinc.com.
