摘要：
A method of detecting intravascular volume depletion in a patient during a hemodialysis session includes measuring venous drip pressure for the patient. With a computer-driven analyzer, the method further includes analyzing the venous drip pressure and automatically and continuously determining a venous access pressure in proximity to a location of needle insertion into a vascular access site of the patient, wherein changes in venous access pressure are representative of changes in intravascular blood pressure. Using the analyzer, the method further includes comparing the venous access pressure to a standard and, if the venous access pressure is outside of a defined range of the standard, determining with the analyzer that the patient is experiencing intravascular volume depletion during the hemodialysis session.
