The INOmax DS
WARNING:
sampling 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
the breathing circuit.
• For proper gas flow measurement, the MR injector module should not be connected directly
Caution:
to the ventilator's inspiratory outlet.
• Connect the MR injector module directly to the humidifier inlet.
• If it is not possible to connect the injector module to the inlet of the humidifier or if a
humidifier is not used, a length of tubing (at least 6 inches) must be placed between the
ventilator patient outlet and the injector module.
Connections to various ventilators are unique to each manufacturer as well as their corresponding
Note:
disposable circuits. Adapter diagrams can be found on page 6-13.

breathing circuit as shown in the appropriate

1. To ensure correct flow measurement, use
breathing circuit tubing between the ventilator
inspiratory port and the MR injector module
(Fig. 3-2).
2. Connect the MR injector module to the
humidifier inlet, note the airflow direction
indicator on the injector module (see Figure
3-3).
3. The distance between the MR injector module
and the sample tee must be greater than 24
inches to ensure proper gas mixing.
4. Insert the sample tee on the inspiratory side
of the ventilator circuit, 6-12 inches (150-300
mm) from the patient wye. This minimizes
the sampling of mixed inspired/ expired
concentrations, and ensures correct patient
NO/NO measurement.

Make sure that the sample tee port points
upward. This helps to avoid fluid accumulation
in the sample line.
