  • Patent number: 11878098
    Abstract: A method includes: receiving measurements of a blood-related parameter corresponding to a patient undergoing hemodialysis; estimating a value of one or more hemodialysis treatment-related parameters by applying a vascular refill model based on the received measurements of the blood-related parameter, wherein the one or more hemodialysis treatment-related parameters are indicative of an effect of vascular refill on the patient caused by the hemodialysis; determining, based on the one or more estimated values of the one or more hemodialysis treatment-related parameters, a hemodialysis treatment-related operation; and facilitating performance of the treatment-related operation. The vascular refill model is a two-compartment model based on a first compartment corresponding to blood plasma in the patient's body, a second compartment based on interstitial fluid in the patient's body, and a semi-permeable membrane separating the first compartment and the second compartment.

  • Publication number: 20210138130
    Abstract: Techniques for vascular access identification and validation are disclosed. The techniques include: directly or indirectly acquiring an acquired value for a parameter that is a function of oxygen saturation (SO2) of a sample of blood in or obtained from a vascular access device (VAD) disposed in a subject; performing an evaluation of the acquired value at least by comparing the acquired value with one or more reference values; and responsive to the evaluation of the acquired value, assigning an identity classification to the VAD, wherein the identity classification is one of a central venous catheter (CVC), an arteriovenous access device (AVA), or another class of VAD.
