9 Ventilator Management
9.1 Ventilator Compatibility list
The NOxBOX
i
sampling flow-rate is approximately 225 ml/min. Please be aware that direct
ventilation on very low tidal volumes may be adversely affected due to high detected leak-rate (%
leak rate) on the ventilator. This can also generate higher NO
2
values due to increased dwell time
for the NO in the lines. To counteract this effect, increasing the bias flow from 2 L/min to 8 L/min
can significantly reduce the effects of both ventilator leak and NO
2
generation.

System Test Fail The NOxBOX
i
has failed the safety test
and cannot accurately deliver and monitor
Nitric Oxide in intelligent mode.
Check the Oxygen source is flowing.
Check the NOxFLOW is connected to the
Oxygen source and the NOxBOXi-TEST kit.
Check the correct orientation of NOxFLOW.
Check the NOxFLOW is connected to the
NOxBOX
i
.
Check NOxFLOW flow detection lines and
connector O rings for damage.
Check sample line is connected to the water
trap and the NOxBOXi-TEST kit.
Check water trap (including barrel thread) for
damage.
Repeat the system test.
If second test fails, replace the NOxFLOW and
sample line.
One or all of the sensors may have
become unstable.
If another system is not readily available and
patient requires therapy, engage the
manual override mode, replace the system as
soon as practically possible and alert the Ser-
vice Engineer.
