A dose determination program for an erythropoiesis-stimulating agent that is executable by a computer. The program causes the computer to perform: obtaining a predetermined target hemoglobin concentration; obtaining a first concentration and a first dose in a stable state in which a hemoglobin concentration is stable at the first concentration by repeatedly administering the first dose a plurality of times, and calculating a second dose of the erythropoiesis-stimulating agent based on the obtained target hemoglobin concentration, the obtained first concentration, and the obtained first dose, the second dose of the erythropoiesis-stimulating agent being to be administered by a fixed amount.

Disclosed herein is a blood pressure measuring device including: a pressure measuring toola fastening memberconfigured to fasten the pressure measuring toolin rest position onto a skin region covering an anastomotic region of a shunt blood vesseland a control circuitconfigured to receive an input signal from the pressure measuring tooland to process the input signal to calculate a pressure inside the anastomotic region of the shunt blood vessel

Blood pressure measuring device

A method of determining an ESA dose, which allows a hemoglobin concentration in the blood to be stably maintained at a target value, and which can decrease a range of fluctuation of the hemoglobin concentration with respect to the target value. The method comprises the steps of: setting the target value of the hemoglobin concentration in the blood; calculating a target value of a hemoglobin production rate which allows the hemoglobin concentration to reach the target value; calculating a serum ESA concentration which allows the hemoglobin production rate to reach the target value, from a relationship between the hemoglobin production rate and the ESA concentration; and calculating an amount of administration of an ESA which gives the serum ESA concentration, from a relationship between the ESA concentration and the amount of administration of the ESA, to determine an ESA dose which allows the hemoglobin concentration to reach the target value.

To provide a non-invasive blood pressure estimation apparatus, which can accurately estimate systolic blood pressure from blood flow sound of a dialysis patient and continuously estimate systolic blood pressure by continuously picking up the blood flow sound. A blood pressure estimation apparatus creates a standard pulse curve by relating a start point and end point of a rising phase of a pulse wave to diastolic blood pressure and systolic blood pressure, respectively, creates a correspondence curve between blood flow sound power and estimated blood pressure by contrasting the standard pulse curve with the blood flow sound power curve obtained from blood flow sound at a shut site, with the two curves plotted on the same time axis, derives a systolic blood pressure estimation linear function from the correspondence curve, inputs a measured maximum value of the blood flow sound power into the linear function, and thereby estimates systolic blood pressure.
