Caution:
Pneumatic nebulizers will dilute the delivered INOMAX dose.

To sample inspired gas during aerosol
delivery:
- Place the medication nebulizer downstream
of the sample tee on the inspiratory limb (see
Figure 3-9).
This avoids over saturation of the water separator
cartridge, or contamination of the sample system.
In addition, it prevents the Sample Line/Filter Block
alarm from occurring.
1. Place the 1.0 micron disk filter on the
INOmax DS Plus MRI sample line inlet
IR
(Fig. 3-10).
2. Connect the patient gas sample line to the
filter. If monitored values change, check that
all sample line and filter connections are
secure.
This disk filter has been validated for this purpose.
After each treatment period, replace the disk filter:
• Change the filter every 12 hours
Note:
or more often if necessary (due to
Sample Line/Filter Block alarm).
Replacing the disk filter reduces the
replacement frequency of the water
separator cartridge.
• Do not operate the INOmax DS
Plus MRI without the water separator
cartridge. Always use the disk filter in
conjunction with the INOmax DS
MRI water separator cartridge.
