ABSTRACT:
A device and method are provided for determining the volume ECVhydr(t) of a body compartment of a patient at a time t by conducting measurements at the time t of the patient to determine at least one anthropometric measure X(t), the extracellular water volume ECV(t), and the intracellular water volume ICV (t) of the patient. The extracellular water volume ECVbasic(t) of a first compartment with weight Wbasic(t) of the patient at the time t is derived by using X (t), the extracellular water volume ECVsec(t) of a second compartment of the patient at the time t is derived by using ICV (t), and ECVhydr(t) as the extracellular water volume of a third compartment of the patient is derived with weight Whydr(t). The extracellular volume ECVhydr(t) is a measure for the hydration status of the patient.
