5.5 Manual bagging & Manual override
5.5.1 Setup
When using the NOxBOX
I
with manual bagging or Neopuff circuit, the Manual Override mode must
be selected (see section 6.12). Adaptors for the below circuits can be obtained from
Bedfont Scientific to ensure compatibility.
The NOxFlow delivery line should be disconnected from the NOxBOX
i
and a manual bag specific
line is connected to the NOxBOX
i
NO outlet port (female leur connection) during manual bagging.
In the case of hyper-inflating and self-inflating circuits, an O
2
supply is typically required and can be
connected to a variable flow O
2
source such as a wall outlet with adjustable flow meter, or a
cylinder with adjustable flow.
Correct NO dose can be calculated and adjusted either by the changing of the manual control
valve position or adjustment the flow rate of the O
2
source (see sections 6.12.1 & 6.12.2).
Monitoring of the dose should be carried out by connection of the sample line to the manual
bagging circuit.
