pNeuton Ventilator 7 - 9
MRI Compatibility
The ventilator was engineered and built to be MRI
compatible. Testing in a MRI scanner has shown that the
scanner does not affect the ventilator’s performance. The
ventilator does not generate artifact, RF noise, or other
deleterious effects on the operation of the MRI scanner or
it's production of an image. In addition, due to
pNeuton
Ventilator components, heating of the ventilator does not
occur during scanning.
Testing for MRI compatibility was done following ASTM
MRI safety standards F2052 – 06e1 and F2119 – 07. The
MRI scanner used has the following maximum
performance levels:

Static field strength - 3 Tesla

Spatial field gradient - 720 G/cm
The scanner used for testing was an active shielded
system. The ventilator was placed in the position of
maximum field strength and maximum spatial gradient.
The standard patient circuit (Airon part number 58031) was
used. A standard imaging sequence with a maximum
scanning time of 5 minutes was used.
The pNeuton Ventilator meets testing
requirements for use within the Magnetic
Resonance Environment with a conditional
marking for safety.
NOTE: Airon recommends that users perform the above
referenced tests in their MRI scanner prior to patient use.
WARNING: While tests show that the ventilator
functions at the bore of the MRI unit, Airon Corporation
does not recommend that the ventilator be clinically used
at or within the bore of MRI scanners. A minimum
proximity of 12 inches (0.3 meter) from the bore should be
