The computing platform determines an individualized erythropoiesis model for the user based on the one or more previous hematocrit and/or hemoglobin measurements and the previous PO2 information, and employs the individualized erythropoiesis model to determine predicted hematocrit and/or hemoglobin measurements. The computing platform performs one or more actions based on the one or more predicted hematocrit and/or hemoglobin measurements.

SYSTEM AND METHOD FOR ADJUSTING HYPOXIA-INDUCIBLE FACTOR STABILIZER TREATMENT BASED ON ANEMIA MODELING
A method for determining a next hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) dosage for a first patient using a patient HIF-PHI model is provided. The method includes obtaining population patient data indicating HIF-PHI dosages and hemoglobin measurements for the patients. Then, virtual patient avatars are generated based on the population patient data. Each of the virtual patient avatars indicates a set of personalized model parameters for a HIF-PHI model. A plurality of HIF-PHI models are determined for the virtual patient avatars. Using the HIF-PHI models, one or more HIF-PHI treatment schemes for administering the HIF-PHI dosages is determined. Subsequently, the HIF-PHI treatment schemes along with a hematocrit and/or hemoglobin concentration for a patient are used to determine a next HIF-PHI dosage for the patient, and the next HIF-PHI dosage is administered for the patient.

The present teachings include techniques for securing a connection to a dialyzer or the like—e.g., securing the junction between a dialyzer port and a connector (e.g., a DIN connector) that couples the port to tubing of an extracorporeal circuit of a hemodialysis system. To this end, a locking device may engage both a DIN connector and a portion of the dialyzer, such as the cap or an adapter engaged therewith. The locking device may include an interior void sized and shaped to accommodate winged portions (or other portions) of the DIN connector to mitigate rotation thereof relative to the port to which it is engaged. Further, the locking device may be used to ensure that coupling between the DIN connector and the port is proper and secure. In this manner, a locking device can mitigate leaks, which can be catastrophic during a hemodialysis treatment or the like.
A dialysis machine includes a user interface for providing visual information and/or spoken information to a user. For example, in some implementations, the user interface may be configured to provide visual information related to an action, such as showing the action being partially or fully completed, and a speaker can provide spoken instructions to assist the user in machine set-up, calibration and/or operation. Such instructions can be particularly useful in a home dialysis setting. In some implementations, the speaker can provide spoken alarms that are related to alarm conditions. The spoken alarms may include patient and/or dialysis machine identifying information. The verbosity of the spoken instructions and/or the spoken alarms may be adjustable, and both may be accompanied by visual information displayed by the dialysis machine (e.g. visual alarms, images and/or video).

DETECTING AND MONITORING OXYGEN-RELATED EVENTS IN HEMODIALYSIS PATIENTS
The present teachings include analyzing oxygen saturation levels sensed during a hemodialysis treatment for a patient to determine whether the patient has a medical condition based on hypoxemia, apnea, or the like experienced during the treatment. To this end, the present teachings may include the use of a machine-learning algorithm trained to identify a presence of a high-frequency intermittent pattern that would be formed in a plot of the oxygen saturation levels, e.g., to determine a severity of respiratory instability experienced. The present teaching may also or instead include a time-series analysis including at least one of: (i) calculating recurrence-based quantification, such as, but not limited to, recurrence rate, determinism, and laminarity; (ii) calculating the optimal recurrence threshold based on maximum variations of the system's determinism and degree of predictability; and (iii) calculating complexity-based measures such as permutation entropy. Such analyses may be used to detect, inter-alia, sleep apnea syndrome.
A device for measuring conductivity of a fluid. The device including a chamber and at least two electrodes. The chamber includes an inlet, an outlet, an upper surface, and a lower surface that runs separate from the upper surface. The fluid enters the chamber through the inlet and flows out of the chamber through the outlet. Moving along a length of the chamber from the inlet to the outlet or from the outlet to the inlet, a distance between the upper surface and the lower surface changes in at least one dimension of the chamber. The two electrodes are configured to measure electrical voltage in the fluid that enters the chamber through the inlet and flows out of the chamber through the outlet.
