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 MR injector module. The
area in green represents the circuit flow range
where the INOmax DS
IR
is rated to deliver NO from 1-80 ppm. (see
maximum NO delivery graph page 1-29).
Display graphic areas in yellow represents
where some inaccuracy of NO delivery is to be
expected.
• The calculated delivery graph displays the
delivered dose as calculated by the delivery
system. The system calculates the dose using
the known variables of flow through the injector
module, INOMAX cylinder concentration and
set dose. The green zone represents that the
delivered dose is within +/- 20% of the set
dose, the yellow indicates a delivered dose
greater (+) or less than (-) 20% of the set dose
(see formula below).
If the NO dose is not set, the
Note:
Calculated Delivery graph will remain
inactive.
Calculated Delivery Formula:
(NO flow / (NO flow + ventilator flow)) * cylinder
concentration
Plus MRI system
