Abstract
Systems, methods, and/or apparatuses may be operative to perform a dialysis process using RBV-based UF control. Embodiments may include methods operative to receive RBV target information comprising population-based dialysis data of real patient outcomes of a patient population associated with the patient, determine an RBV value of a patient during the dialysis process, and determine UF information to control a UF pump of the dialysis device to maintain the RBV value within a target RBV range defined by the RBV target information. Other embodiments are described.
Claims12
A method comprising:
- performing a hemodialysis (HD) treatment on a patient using a dialysis machine;
- determining a target ultrafiltration rate (UFR) using a computing device operably coupled to the dialysis machine, the computing device comprising a memory storing instructions and a processor, responsive to executing the instructions, operative to determine the target UFR via:
- determining RBV target information for the patient based on population-based dialysis data of real patient outcomes of a patient population sharing at least one characteristic of the patient, the RBV target information comprising desired RBV target ranges for the patient during the dialysis process;
- measuring relative blood volume (RBV) values of the patient during the dialysis treatment;
- comparing the RBV values to the RBV target information;
- determining the target UFR to maintain future RBV values of the patient during the dialysis treatment within the RBV target ranges;
- and
- communicating the target UFR to the dialysis machine;
- and
- controlling a UFR of the dialysis machine to correspond to the target UFR during the HD treatment.
