APPENDIX B
MRI TEST
The Bio-Med Devices IC-2A MRI ventilator was tested approximately 2 ½ feet inside the
bore of a 1.5 tesla MRI unit at which point the magnetic field was estimated to be 13,000
gauss.
The results of the test were as follows:
1. There was no detectable magnetic attraction of the ventilator.
2. The operation of the ventilator was not affected.
3. There was no effect on the MRI image.
Although this test was performed within the bore of the MRI unit, Bio-Med Devices does
not recommend the ventilator be placed inside the bore in practice. Minimum proximity
of one meter should be observed.
