system at 230 mL per minute which can cause the ventilator to auto-trigger.
Adjusting the flow sensitivity may be necessary. The trigger sensitivity of the
ventilator should be checked after connecting the INOmax DS
circuit.
• For proper gas flow measurement, the injector module should not be connected directly to
Caution:
the ventilator's inspiratory outlet.
• Connect the injector module directly to the dry side of the humidifier chamber.
• If it is not possible to connect directly to the dry side of the humidifier, a filter or length
of tubing may be placed between the inspiratory outlet and injector module which will
condition the ventilator flow.
Connections to various ventilators are unique to each manufacturer as well as their corresponding

Connect the INOmax DS
as shown in the appropriate connection diagrams
later in this section.
1. To ensure correct flow measurement, use
breathing circuit tubing between the ventilator
inspiratory port and the injector module (Fig.
3-1).
2. Connect the injector module prior the humidifier
chamber on the dry side of the breathing circuit
to ensure correct flow measurement.
3. The distance between the injector module and
the sample tee must be greater than 24 inches.
This ensures proper gas mixing, minimizes
the sampling of mixed inspired/expired
concentrations, and ensures correct patient NO/
NO measurement.

4. Insert the sample tee on the inspiratory side of
the ventilator circuit, 6-12 inches (150-300 mm)
from the patient wye.
Make sure that the sample tee port points
upward. This helps to avoid fluid accumulation in
the sample line.
