Bella vista vent was alarming "circuit occlusion" and prematurely terminating breaths on a paralyzed patient.This is a recurring issue with this ventilator when ventilating severely ill patients on volume targeted pressure ventilation.The ventilator circuit was not kinked or occluded.High pressure alarm was increased, and p insp max was raised to 50 cmh2o.Vent was still alarming occlusion and prematurely terminating breaths.The ventilator was then switched out of target ventilation and into conventional v-ac where the patient began ventilating with peak pressures of 40 and under.Patient was prone and on a nimbex drip.A short time later, the vent mode was switched back to target ventilation and it immediately started alarming "circuit occlusion again".The mode was immediately switched back to v-ac and it began alarming volume low due to high pressure limit.At this point, the vent mode was changed to p-ac and the ventilator was switched out with a different brand.Fda safety report id # (b)(4).
