title: Investigation of the new prediction method for Ht values during the plasma exchange.
abstract: There is a disorder that is called Guillain-Barre Symdrome(GBS). Currently, plasmapheresis and high-dose immunoglobulin therapy are used for GBS. Plasmapheresis is one of the blood purifications. When the blood purification is enforced, it should be careful to decrease the blood pressure. In the Tokushima University Hospital, the hematocrit(Ht) values are measured using Crit-Line Monitor(CLM), because the Ht values are rate of red cell in blood, and are relation of the blood pressure. Hence, it is important to predict Ht value using the prediction method. There are various prediction methods, but we proposed the new prediction method. The purpose of this study is the prediction of Ht value after 1,3, and 5 minutes during the plasma exchange using the new prediction method. As the results, rms errors were small in all prediction, but the predicted Ht values are same the measured Ht value before 1,3, and 5 minutes, because the measured Ht values are strong autocorrelation.
