Abstract

We have assessed the performance of a series of ventilators (modified versions of the ventiPAC, paraPAC and babyPAC ventilators; SIMS pneuPAC Ltd, Luton, UK) in a magnetic resonance imaging (MRI) scanning environment, with MR safety and compatibility issues being addressed. Following initial modifications to remove ferromagnetic components and replace them with MR-safe materials, all three ventilators performed well in a series of tests in static magnetic fields up to 2 T. Ventilator performance was unaffected by static fields, switching gradients or radio frequency fields within the MR suite. Furthermore, the devices produced no degradation of image quality when used during MR scanning. We discuss management strategies for the care of critically ill ventilated patients during MR procedures.
