INOblender Schematic Diagram
Theory of Operation
1. The INOblender connects to a 3-5 bar (45-75 psig) oxygen supply. The oxygen flow is then
controlled by an integrated oxygen flow meter (2-14 lpm). There is a fixed restrictor in the oxygen
flow path which creates a pressure proportional to the oxygen flow rate.
2. The INOblender is also connected to a 2 bar (30 psig) INOMAX (800 ppm or 400 ppm) supply.
• The
INOMAX flow is controlled by a balance regulator in proportion to the oxygen pressure
caused by the fixed restrictor and the INOblender setting.
• The balance regulator maintains a constant INOMAX dose for varying oxygen flow rates.
3. The flows of O
2
and
INOMAX are mixed prior to exiting the INOblender outlet.
