Settings Screen (third level)
• The circuit flow graph, combined with
calculated delivery graph, is a user level tool to
ascertain NO delivery system limitations in the
context of mechanical ventilation.
• The circuit flow rate graph displays the
real time peak and average flow rate in the
breathing circuit over a 10 second time period,
as measured by the injector module. The
area in green represents the circuit flow range
where the INOmax DS
IR
system is rated to
deliver NO from 1-80 ppm. (see maximum NO
delivery graph page 1-25). Display graphic
areas in yellow represents where some
inaccuracy of NO delivery is to be expected.
• The calculated delivery graph displays the
delivery subsystem calculated % error in NO
delivery compared to the desired set dose
over a 10 second time period. The green
to yellow transition points are defined to be
NO delivery error of +20% (over-delivery)
to -20% (under-delivery) compared to the
desired NO set dose. High set dose levels,
high peak inspiratory flows and proportional
NO flow control inaccuracies can contribute
to the indicating arrow varying from the ideal
midpoint.
Note: • If the NO dose is not set, both graphs
will remain inactive.
• See page 1-25 for further explanation
of maximum deliverable NO
concentration.
