may be inappropriately set.
Confirm high NO alarm limit is set appropriately.
b. Circuit setup incorrect. Check circuit for correct setup.
c. The NO calibration may
have drifted.
1. Perform low calibration.
2. Perform high NO calibration.
d. Injector module may not be
functioning properly.

WARNING:
• Abrupt discontinuation of INOMAX may lead to worsening oxygenation and
increasing pulmonary artery pressure, i.e., Rebound Pulmonary Hypertension
Syndrome. To avoid abrupt discontinuation, utilize the INOblender or integrated
pneumatic backup if necessary. If Rebound Pulmonary Hypertension occurs,
reinstate INOMAX therapy immediately. (See the INOMAX prescribing
Information for further details).
• If the high NO
2
alarm activates, the delivery system should be assessed for
proper setup while maintaining INOMAX delivery. Adjust INOMAX and/or FiO
2
as appropriate. (See INOMAX Prescribing Information for further details on
the effects of Nitrogen Dioxide, NO
2
). If unable to determine the cause of the
increased NO
2
levels, call technical support and do not discontinue therapy.
