The invention provides a system for continuously monitoring a patient during hemodialysis. The system includes a hemodialysis machine for performing the hemodialysis process that features a controller, a pump, a dialyzer filter, a lumen, and an interface to a body-worn monitor. A patient attaches to the dialysis machine through the lumen, and wears a body-worn monitor for continuously measuring blood pressure. The monitor includes an optical system for measuring an optical waveform, an electrical system for measuring an electrical waveform, and a processing component for determining a transit time between the optical and electrical waveforms and then calculating a blood pressure value from the transit time. The body-worn monitor features an interface (e.g. a wired serial interface, or a wireless interface) to transmit the blood pressure value to the controller within the hemodialysis machine. The controller is configured to receive the blood pressure value, analyze it, and in response adjust the dialysis process.

A method and system for use in measuring the endothelial dysfunction utilizing flow mediated dilation and determining arterial health of a patient. The system includes a non-invasive blood pressure monitor, an ultrasound system and a pulse oximeter monitor that all communicate with each other to perform the flow mediated dilation. Initially, the ultrasound transducer, blood pressure cuff and pulse oximeter sensor are positioned on an arm of the patient. The blood pressure cuff is inflated to occlude an artery for an occlusion period. Following the occlusion period, the ultrasound system is automatically signaled to begin determining a parameter of the artery, such as diameter, and the flow rate of blood through the artery without any operator intervention. At the same time, the pulse wave velocity PWV is calculated between the ultrasound transducer and the finger probe of the pulse oximeter following the occlusion period. Based upon the detected characteristics of the artery before and after occlusion, as well as the PWV, the system can determine the endothelial dysfunction and arterial health of the patient.
