Mechanical ventilation during magnetic resonance imaging (MRI) requires a specially constructed ventilator that contains no ferromagnetic components; however, the expense of acquiring such a ventilator may not be warranted if projected use is infrequent. We adapted a Laerdal manual resuscitator to allow its use during MRI, and report the simulation and monitoring procedure that we developed and the successful ventilation of three pediatric patients with the device.
Taylor et al. (Fri,) studied this question.
