3.5.3 Trigger Sensitivity
When using synchronised ventilator modes, the net change of gas volume flow caused by the
NOxBOX
i
may trip the trigger flow setting. Always check the trigger sensitivity of the ventilator after
connecting the NOxBOXi to the patient circuit.
3.5.4 Maximum NO Dose Delivery
The NOXBOX is capped at maximum dose capability of 80 ppm in software.
Additionally, the maximum flow capability of the NOxBOX
i
is physically limited. This will cause
some dose limitations at higher ventilator flow rates.
The NOxBOX
i
is compatible with a wide range of NO supply concentrations, note that the physical
flow limitation has less effect on the 1000 ppm cylinder supply compared to the 400 ppm supply.
See Figure 3.5.4 1: Graph of NOxBOXi Maximum Dosing Capability.
