O

Conserve Mode
In order to use a low-pressure oxygen
source without causing a Low Oxygen
Source alarm, O
2
Conserve mode must be
enabled on the CCV. This mode allows
the CCV to use an oxygen source below
2.8 Bar (40 psi), and also limits the allowable flow of oxygen during
inspiration to 10 LPM. It should be engaged when attempting to make a
cylinder last longer, or whenever a low-pressure oxygen source is used.
To enable O
2
Conserve mode, connect an oxygen source and ensure
that Control Lock is not engaged. Press the O
2
Conserve button in the
Additional Settings panel of the CCV interface. The green light will
come on when O
2
Conserve mode is engaged.
If the ventilation settings are changed such that more than 10 LPM of
oxygen is used while in O
2
Conserve mode, the red alarm light will turn
on in the Ventilation Settings panel next to the message “%O
2
Setting
cannot be achieved in O
2
Conserve Mode.”
If this light comes on, the CCV is outputting a lower oxygen
concentration than the displayed setting. Immediately alter the
settings until the light goes back off
. This can be done by:
a.
Decreasing the %O
2
,
b.
Decreasing the Vt, or
c.
Increasing the I. Time.
Until the red warning light goes off
again, the %O
2
value will not reflect the
oxygen concentration that is being
delivered to the patient.
