INOblender Operation

WARNING:
system before the manual resuscitator bag is connected to the patient.
• The manual bag should be squeezed repeatedly during use to avoid NO
up in the bag.
• If the bag is not squeezed repeatedly while delivering INOMAX, the bag should
be removed from the patient and the bag purge procedure performed before
continuing.
• The INOblender should be upright when setting the oxygen flowrate for accurate
setting.
• Do not use pneumatically powered nebulizers with the INOblender. This will result
in significant over delivery of INOMAX in excess of 80 parts per million (ppm).
- The INOblender outlet pressure has been validated for use up to 400 millibar
- In addition, the INOblender flowmeter is not back-pressure compensated
• When not in use, the oxygen flowmeter should be turned off.
Caution:
• A user may determine that some clinical conditions may necessitate the use of an oxygen/air
blender with the INOblender to achieve FiO
• Delivered INOMAX dose from the INOblender is affected by varying oxygen concentrations

(5.8 psig) pressure. The amount of back-pressure generated by pneumatic
nebulizers is significantly greater (20-30 psig) and will result in over delivery
of INOMAX in excess of 80 ppm. The user adjusted dose setting on the
INOblender will not correlate with, or have an effect on the actual delivered
dose.
