USING THE CCV WITH A CONCENTRATOR OR FLOWMETER
The CCV may be used with a low flow source such as an oxygen
concentrator or flowmeter, provided the source can maintain an output
pressure of at least 0.7 Bar (10 psi). To use a low flow source the CCV
must be configured to utilize the oxygen reservoir, and O

Mode must be engaged.
CCV Reservoir
Because the flow rate of a concentrator or flowmeter is generally lower
than the flow rate required by the patient during inspiration, a low flow
source alone would not be able to act as a usable oxygen source
because it could not keep up with patient demand and would
consistently cause a Low Oxygen Source alarm.
To resolve this, the CCV utilizes a reservoir
which stores sufficient gas to allow the
patient to take a full breath, allowing a
concentrator or flowmeter to be used. Gas
from the reservoir is used during inspiration
(at any flow rate required by the ventilation
settings), and the reservoir is refilled by the
oxygen source during exhalation.
NOTE: The CCV reservoir is not an
emergency supply of gas and will not hold
sufficient volume to ventilate a patient for
any significant period of time beyond a
single breath.
The CCV reservoir is a simple tank mounted
to the bottom of the stand basket. The
reservoir has two ports on the left side (while
facing the machine): a hose barb inlet threaded fitting outlet to be
connected to the CCV’s DISS port via the provided hose. When not in
use, both ports should be plugged, the inlet by leaving the provided
flexible silicone hose attached for quick access, and the outlet by the
provided red plastic cap. Keeping the ports plugged will prevent any
cleaning fluid from entering the reservoir, which would then pose a
danger to the patient as fumes or vapors could be inhaled.
