The present invention discloses a detection device for detecting irregular intravascular pressure, the device including an analyzer for automatically analyzing intravascular pressure upstream of the suspected location of irregular blood flow, and a comparing device that correlates the recorded intravascular pressure to a standard whereby variation in the intravascular pressure during multiple tests is indicative of irregular blood flow. Also disclosed is a system for providing a warning of potential health problems due to irregular blood flow, the system including a detecting device as set forth above and a communicating device operatively connected to the detecting device for communicating a warning when the device indicates an irregularity of intravascular pressure during at least two uses of the device.

Access pressure ratio device and testing method

A method and system for continuously monitoring patient heart rate and blood pressure during hemodialysis and for automatically controlling fluid extraction rate and/or dialysate sodium concentration in the event that blood pressure and/or heart rate indicate onset or impending onset of a patient hypotensive episode. A decrease in patient blood pressure below preselected systolic and/or diastolic low alarm limits automatically initiates a second mode of therapeutic intervention wherein sodium concentration in the dialysate is increased for a predetermined time duration. Upon detection of such low blood pressure alarm, or upon detection of an increase in patient heart rate above a preselected alarm limit, the extraction rate of fluids from the patient through the ultrafiltration membrane is reduced in a first mode of therapeutic intervention by reducing such fluid extraction rate to a minimum level. Blood pressure and heart rate are thereafter monitored during this second mode of intervention to return ultrafiltration flow rate to its desired or goal level as blood pressure and heart rate indicate return of patient vital signs toward their initial levels.

Automated hemodialysis control based upon patient blood pressure and

A method and apparatus for administering large quantities of blood which has been stored at less than ambient temperatures continuously and rapidly to a patient at physiologically acceptable temperatures and pressures in a short time wherein the blood is continuously directed through a plurality of discrete capillary paths in heat-exchange relationship with a warming medium, the number of said paths being such that the pressure of the blood is not substantially increased, and the blood is rapidly administered directly to a patient.
