(b)(4) manufacturing review and sterilization process review investigation: fluids used during the procedure were anticoagulant (acda), saline (b)(4) and fresh frozen plasma (ffp) was used for replacement fluid.The customer stated that the patient had ttp, suffered labored breathing, and had low oxygen saturation levels before the procedure began.Functional checkout of the machine was performed by a terumo bct service technician.All functional tests met specifications.A saline run with all alarm tests was performed without failure.All tests passed.The run data file (rdf) was analyzed for this event.The signals in the rdf indicated that the system operated as intended.According to a published article in the american journal of emergency medicine, cardiac arrest can be linked to ttp disorder.Because ttp is a disease characterized by thrombi in micro circulation throughout the body, the flow of blood to the lungs can become limited or blocked.When this occurs, it is referred to as pulmonary embolism.Fulminant pe shows a high prevalence and often degenerates into cardiopulmonary arrest.Spectra optia apheresis essentials guide provides the following cautions: "the physiological condition of patients may affect the outcomes of procedures performed on the spectra optia system." a review of the device history record (dhr) for this unit showed no irregularities during manufacturing that were relevant to this issue.The patient¿s official release record and/or autopsy report were requested from the hospital¿s medical records department.Information, such as name, dob, and ssn, was stated as necessary to obtain those records.Previous attempts to obtain the patient id were unsuccessful and therefore, the official medical report(s) could not be obtained.Root cause: the definitive cause for the patient¿s death is undetermined but is not alleged to be due to the spectra optia system.Based on the nurse's description of events, dlog analysis,and machine service inspection, the likely root cause was the patient's disease state, but this could not be confirmed by the physician or with medical records.
