If issues persist, remove the barrel and check
position of alarm float.
Removing the water trap barrel will dilute
NO sample causing inaccurate dose and
readings. Take care not to damage/cross
thread the water trap thread when replacing
the barrel.
Sample
Line
Block
Sample line to monitor has
become blocked, pinched or occluded.
Sample monitoring is affected which
may compromise delivery accuracy and
patient safety.
Check sample line for any pinch/crush points
from external bodies, or
blockages that may have occurred.
Check water trap does not require emptying.
Change sample line and filter.
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
Service Engineer.
Battery
Critical
NOxBOX
i
is running from internal battery
and battery charge level has been
detected as critical. System power could
fail within the next 10 minutes.
Power failure will stop automatic
intelligent delivery of NO.
Reconnect the NOxBOX
i
system to the mains
using the NOxBOX
i
power supply. This will
ensure continued powered operation of the
NOxBOX
i
and will start to recharge the internal
battery.
Check green (mains power) L.E.D on mains
power plug is lit indicating mains supply OK. If
not, try a different mains power socket/supply.
Disconnect power supply and
reconnect, check blue (charging) L.E.D is lit
indicating mains supply OK. If not, try a
different mains power/supply.
If possible replace NOxBOX
i
power supply and
alert service engineer.
In the event that no mains power can be
restored to the device, be prepared to engage
the manual override mode.
Cylinder
Supply
Critical
NOxBOX
i
detects that available NO gas
supply is running low, and no alternate
cylinder supply is detected. Without
action to replenish the NO gas supply
treatment delivery will cease.
Install a new gas cylinder supply and connect
to the alternate gas inlet port at the rear of
NOxBOX
i
.
If a new gas cylinder is already installed,
ensure the cylinder valve is fully open and
connected to inlet port at rear to allow the
device to use the supply for delivery.
Check the supply cylinder regulator gauges
indicate adequate cylinder pressure (>20bar).
If regulator gauge indicates adequate pressure,
check for leaks. If issues persist, replace
regulator and alert service engineer.
Vent flow
Idle
The NOxFLOW has not detected any
vent flow activity for an extended
period of time (typically over 30
seconds) during delivery.
Check correct orientation of NOxFLOW; the
green arrow printed on the NOxFLOW should
be pointing towards the patient in the direction
of the ventilator flow.
Check NOxFLOW flow detection lines and
connection (including O rings) are connected
and there are no blockages or leaks.
Check there is not a serious leak or break in
the ventilator circuit. Attend to the ventilator
circuit requirements.
