An apparatus and a method for increasing the safety of an extracorporeal blood treatment based on the monitoring of the transmembrane pressure. Of during treatment with a measuring device (24) measured transmembrane pressure TMP is compared with an upper and lower limit value L 1, L 2, which define a monitoring window. If the transmembrane pressure outside of the monitoring window, is added with an alarm device (27) an alarm. The monitoring window is shifted depending on the ultrafiltration rate. To determine the window limits the transmembrane pressure is calculated in a computing unit (25a), which should be adjusted according to a change in the ultrafiltration rate UFR. then the window limits are determined on the basis of the expected transmembrane pressure.
