The process of removing excess fluid from a patient's blood during dialysis by applying pressure across the dialyzer membrane.
Ultrafiltration is the mechanism by which excess fluid accumulated between dialysis sessions is removed from the patient's body. The UF rate (measured in mL/hr) is calculated based on the patient's interdialytic weight gain and target dry weight. Excessive UF rates (>10 mL/kg/hr) are associated with intradialytic hypotension, cardiac stunning, and increased mortality. Modern dialysis machines allow precise UF profiling, and monitoring UF rate in real-time is a critical safety function that ZuvFlo automates with threshold alerts.
A medical procedure that filters waste products, excess fluids, and toxins from the blood using a dialysis machine when the kidneys can no longer perform this function adequately.
The target body weight of a dialysis patient after all excess fluid has been removed — the weight at which blood pressure is normal without medication.
A sudden drop in blood pressure during a dialysis session, occurring in 20-30% of sessions and representing the most common intradialytic complication.
The artificial kidney component of a dialysis machine containing a semipermeable membrane that filters waste and excess fluid from blood.
