Integrated Pnuematic Backup NO Delivery
• When using the integrated pneumatic backup with breathing circuit gas flows of
WARNING:
5 L/min, the delivered NO dose will be approximately 40 ppm. Breathing circuit
gas flows less than 5 L/min will deliver an NO dose greater than 40 ppm.
• The integrated pneumatic backup is intended for short term use when the
electronic delivery system fails until a replacement NO delivery device can be
brought to the bedside.
• The integrated pneumatic backup delivers a variable concentration of NO to the
patient depending on the ventilator flow being used. See table below for details.

Integrated Pneumatic Backup NO Delivery
Description
The integrated pneumatic backup delivery provides
a fixed flow of 250 ml/min of INOMAX directly
into the ventilator circuit through the MR injector
module.
The integrated pneumatic backup is not reliant on
the operation of the main system (see Figure 3-6).
• The integrated pneumatic backup delivery is
activated through the backup switch on the front
panel. When activated, the set INOMAX dose will
be automatically turned OFF. The high and low
NO alarms are automatically set to 90 and 5 ppm
respectively (see Figure 3-4).
• The estimated backup dose graphic (if displayed)
represents the estimated dose the patient is
receiving, by displaying a dose indicator. The
estimated backup dose is calculated by using the
circuit flow measured by the MR injector module
(see Figure 3-4).
• The estimated NO dose table is also displayed
on the main screen.
• If the MR injector module is not

functioning, the estimated backup dose
graphic will be inactive.
• The estimated backup dose graphic
and the estimated backup dose based
on ventilator flow table, will not be
present during a Cylinder Concentration
Mismatch alarm.
