A blood filtration system may include blood circuit configured to transmit a fluid within one or more lumens. The system may include an optical sensor configured to couple with the blood circuit. The optical sensor may measure one or more optical characteristics of the fluid in the blood circuit. The one or more optical characteristics may include a first optical characteristic corresponding to a concentration of an imaging substance in the fluid within the blood circuit. The system may include a controller in communication with the optical sensor. The controller may include a sampling module configured to record the one or more optical characteristics. The controller may include a physiological characteristic identification module configured to determine a plasma volume of the patient with the recorded optical characteristics of the imaging substance.

A blood flow stimulator may help encourage blood flow in a limb of a patient. The blood flow stimulator may include a housing configured for sealing about the limb of the patient. The housing may include a sealable volume, and the sealable volume may receive the limb of the patient. The blood flow stimulator may include a seal, and the seal may be coupled with the housing. The seal may engage with at least a portion of the limb, for instance to segregate the sealable volume from a surrounding environment of the blood flow stimulator. The blood flow stimulator may include a conduit extending through the housing. The conduit mat help provide access to the sealable volume, for instance from the surrounding environment. In some examples, an adjustable stent is utilized to enhance blood flow within vasculature of a patient. A stent operator may change a size of the stent.

A blood filtration system may to couple to an infusion pump that is external to the blood filtration system. The blood filtration system may include a blood circuit, for instance a variable-volume blood circuit. An infusion port may be in communication with the blood circuit and may receive an infusion fluid pumped by the infusion pump. A filtration pump may extract a filtrate fluid from a filter. The filtrate fluid may include filtered plasma constituents. A fluid characteristic sensor may measure one or more of pressure or flow rate of the infusion fluid pumped by the infusion pump. A controller may monitor the fluid characteristic sensor to determine a change in the pressure or flow rate of the infusion fluid. The controller may modulate a speed of the variable-speed filtration pump based on the change in the pressure or flow rate of the infusion fluid.

A portable arm support can be secured to an arm of a patient, for instance during a medical procedure (e.g., filtration of blood of the patient). The arm support can inhibit movement of the arm of the patient in one or more degrees of freedom (e.g., elevation, abduction, adduction, flexion, or the like). In some examples, the arm support includes a cuff and a base. In another example, the arm support includes an elongated member. In yet another example, the arm support includes a constricting band. The arm support can help maintain blood flow in the arm of the patient, and can help protect a catheter inserted into the arm of the patient (or protect other medical equipment proximate to the patient).

A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.
