- Ht is measured by blood samples analysis. TBV and TPV are calculated according to Ht, weight and height of the patient at each sessions. EPV is the volume extracted and treated by the machine at the end of the sessions then expressed in TPM (maximal objective at 1,4). All the previous parameters are the average of all the sessions per patients.
- CVL refers to the need of CVL for at least one session.
- FFP refers to the need of partial or complete replacement of albumin 4% by FFP to avoid hemorrhagic risk due to dilution coagulopathy.
- IAE refers to complications of the plasmapheresis sessions.
TBV: total blood volume (liters); Ht: hematocrit (%); TPV: total plasma volume (liters); EPV: extracted plasma volume (liters); SD: standard deviation; TPM: treated plasmatic mass; CVL: central venous line; FFP: fresh frozen plasma; IAE: iatrogenic adverse events; VAR: vagal adverse reaction; APE: acute pulmonary edema; na: not available.
