WARNING:
for more than one hour will result in interruption of INOMAX delivery.
The INOmax DS Plus MRI has an interface using infrared (IR) technology which allows the
IR
INOmax DS Plus MRI to communicate with the INOmeter (which is mounted to each INOMAX cylinder).

The INOmax DS Plus MRI cart (PN 10076) has a cover (see Figure 1-12,

Caution:
Nothing should be placed between the INOmeter and the cart to which it is attached.
Magnetic Interference
A strong magnetic field such as that from an MRI system can affect the ability of
WARNING:
the INOmeter to detect if the cylinder valve is open. This can cause a "Cylinder
Valve Closed" alarm to occur when the cylinder valve is actually open. If this alarm
occurs, reposition/rotate the INOmax DS
to reduce the magnetic interference in the area of the INOmeter until the cylinder
handle graphic on the display turns green. This will resolve the "Cylinder Valve
Closed" alarm. Typically the required INOmax DS
is less than 6 inches (15 cm) / 90 degrees. Note that Interruption of INOMAX therapy
will occur one hour from point when the "Cylinder Valve Closed" alarm is activated if
the alarm is not resolved.
Communication Interference
The INOmax DS Plus MRI transceiver is located under the cart cover and should be protected from outside
IR
interference. The INOmax DS

projecting towards the floor (see dotted lines in Figure 1-12). The specifications of the IR beam call for it to
have a range of 20 cm (7.9 in). Based on these specifications it should not affect other devices in the vicinity
of the INOmax DS Plus MRI.
IR
The INOmeter uses a lower energy source which results in a lower IR beam range than the
INOmax DS Plus MRI cart. The INOmeter does not transmit IR signals unless it is mounted on the
IR
INOmax DS Plus MRI cart.
