Investigation: the run data file (rdf) was analyzed for this event.No definitive root cause for the reported adverse events could be identified from the rdf and there were no issues during the procedure.The following alarms occurred during the procedure: 1x return pressure was too high when system was diverting saline 1x return pressure was too high.1x interface took too long to establish access alarms alone are not known to cause adverse events but the excessive occurrence of them points toward issues with the patient access.The constant alarming of the device combined with frequent manipulation of the access may have caused increased agitation in the patient and resulted in the adverse event for some of these procedures.The most common source of inlet pressure alarms is when the inlet flow rate is set too high for the given patient access, the patient access is occluded/blocked, or the patient access is not properly positioned.In response to inlet pressure alarms, it is suggested to ensure the patient access is appropriately sized and positioned, nothing is blocking the access line, and to lower the inlet flow rate.Throughout the procedure the ac was returned at 0.9ml/min/ltbv to the patient.No other potential sources of a patient reaction were identified.The system operated as intended and the procedure was run within standard operating limits (i.E.Not in ¿caution status¿).Investigation is in process.A follow-up report will be provided.

This report is being filed to provide additional information in b.5, h.6, and h.10.Corrected information is provided in b.6.Root cause: no definitive root cause for the reported adverse events could be identified from the dlogs associated with these procedures.The system operated as intended and the procedures were run within standard operating limits (i.E.Not in ¿caution status¿).The procedure on (b)(6) had 64 ¿inlet pressure was too low¿ alarms and 24 ¿return pressure was too high¿ alarms.353ml of ac was delivered to the patient over the course of the procedure.Access alarms alone are not known to cause adverse events but the excessive occurrence of them points toward issues with the patient access.The constant alarming of the device combined with frequent manipulation of the access may have caused increased agitation in the patient and resulted in the adverse event for some of these procedures.The most common source of inlet pressure alarms is when the inlet flow rate is set too high for the given patient access, the patient access is occluded/blocked, or the patient access is not properly positioned.In response to inlet pressure alarms, it is suggested to ensure the patient access is appropriately sized and positioned, nothing is blocking the access line, and to lower the inlet flow rate.Throughout the procedures the ac was returned at 0.9ml/min/ltbv to the patients during the four mnc procedures and 1.2ml/min/ltbv for the one cmnc procedure.No other potential sources of a patient reaction were identified.In summary, a definitive root cause for the patient's reaction could not be determined.Possible causes for the alleged citrate reaction include but are not limited to patient disease state and/or patient sensitivity to anticoagulant.

This report is being filed to provide additional information in h.10.Investigation: according to therapeutic apheresis: a physician's handbook, adverse events occur during therapeutic procedures with a frequency of 4.8%.Transient hypocalcemia associated with apheresis is ususally well tolerated.Symptoms often show as parasethesia (tingling) but patients may also experience unusual taste, nausea, lightheadedness, shivering, and tremors.Severe hypocalcemia may also cause muscle contractions and can progress to tetany and seizures if hypocalcemia escalates and is not corrected.Investigation is in process.A follow up report will be provided.
