Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. The core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in; for example, in humans, the output (via respiration, perspiration, urination, defecation, and expectoration) must equal the input (via eating and drinking, or by parenteral intake). Euvolemia is the state of normal body fluid volume, including blood volume, interstitial fluid volume, and intracellular fluid volume; hypovolemia and hypervolemia are imbalances. Water is necessary for all life on Earth. Humans can survive for 4 to 6 weeks without food but only for a few days without water.
Measuring effective circulating volume and estimating changes in total body water during dehydration and rehydration
The present invention provides a system and method for measuring the effective circulating volume (ECV), and for estimating changes in total body water (TBW) during the dehydration and rehydration phases. This invention is applicable in clinical and non-clinical settings, including but not limited to sports performance monitoring, medical diagnostics, and managing fluid balance in patients with cardiovascular or renal conditions.

Peritoneal dialysis fluid balance monitoring system and method with dynamic weighing and data fusion
The present application relates to the technical field of peritoneal dialysis monitoring, and discloses a peritoneal dialysis fluid balance monitoring system and method based on dynamic weighing and data fusion. The system comprises dynamic weighing, multi-source data acquisition, data fusion processing, balance monitoring and early warning output modules. The dynamic weighing module acquires the input and output amounts of dialysis fluid in real time and generates weight data; the multi-source data acquisition module obtains dialysis fluid composition, treatment time and patient physiological parameters; the data fusion processing module fuses the above data to generate dialysis fluid balance characteristic data; the balance monitoring module calculates the net ultrafiltration amount and the fluid balance state according to the above data, and identifies the risk of abnormal leakage or fluid retention; and the early warning output module generates early warning information when the risk is identified. The system does not require manual intervention, can acquire and fuse multi-source data in real time, accurately judges the fluid balance state and timely generates early warning information, and is suitable for hospital and home peritoneal dialysis scenarios.
