WARNING:
1. Avoid recirculation of gases.
Undesired recirculation of gases
will occur if fresh gas flows are less
than the patient minute volume and
may result in:
• Higher NO
2
levels due to the
limited ability of the carbon
dioxide absorbent to remove
NO
2
.
• Higher concentrations
than those set due to NO
recirculated through the
absorber.
• Reduction in O
2
concentrations
because nitrogen is the
balance gas for nitric oxide
and will be present in the re-
circulated gases.
2. If the Injector Module was used
in the wet/humidified part of the
breathing circuit, it should be
sterilized between each patient use.
Caution:
1. Note airflow direction on the
Injector Module: the flow out of the
absorber must pass through the
Injector Module in the direction of
the arrow on the module.
2. Nitrous oxide (N
2
O) will affect
the Set NO versus the measured
NO value. For a 50% N
2
O, 50%
O
2
composition, the measured
NO value will be approximately
7% indicated less than the
same Set NO value of 100%
O
2
. For example, at a Set NO
of 20 ppm, measured NO will be
approximately 18 ppm.
3. Similarly, the effect of 2%
v/v isoflurane will result in a
high measured NO value of
approximately 3% indicated for the
same Set NO value at 100% O
2
.
4. Sudden changes in anesthetic
agent concentration may cause
brief transient changes in the
measured NO and NO
2
values.
