Abstract
A method for monitoring of peritonitis in a peritoneal dialysis patient is presented. The method includes: accessing a hydration status of the patient; determining a threshold turbidity level for diagnosing a potential case of peritonitis based on the hydration status of the patient; accessing a turbidity measurement of PD effluent of the patient; determining whether the turbidity measurement exceeds the threshold turbidity level; and generating a warning responsive to determining that the turbidity measurement exceeds the threshold turbidity level.
Claims20
A method for monitoring of peritonitis in a peritoneal dialysis patient, the method comprising:
- accessing a hydration status of the patient;
- determining a threshold turbidity level for diagnosing a potential case of peritonitis based on the hydration status of the patient;
- accessing a turbidity measurement of PD effluent of the patient;
- determining whether the turbidity measurement exceeds the threshold turbidity level;
- and
- generating a warning responsive to determining that the turbidity measurement exceeds the threshold turbidity level.
A system for monitoring for peritonitis in a peritoneal dialysis patient, the system comprising:
- at least one controller configured to:
- access a hydration status of the patient;
- determine a threshold turbidity level for diagnosing a potential case of peritonitis based on the hydration status of the patient;
- access a turbidity measurement of PD effluent of the patient;
- determine whether the turbidity measurement exceeds the threshold turbidity level;
- and
- generate a warning responsive to determining that the turbidity measurement exceeds the threshold turbidity level, wherein the warning indicates the turbidity measurement exceeds the threshold turbidity level set for diagnosing a potential case of peritonitis.
A method of monitoring a peritoneal dialysis (PD) patient, the methods comprising:
- accessing a plurality of hydration measurements of the PD patient corresponding in time to a plurality of dialysis treatments;
- accessing a plurality of turbidity measurements of the PD effluent of the PD patient corresponding to the plurality of dialysis treatments;
- accessing a plurality of ultrafiltration volume (UFV) measurements of the PD patient corresponding to the plurality of dialysis treatments;
- accessing a plurality of PD prescriptions of the patient corresponding to the plurality of dialysis treatments;
- determining a correlation between the plurality of hydration measurements of the PD patient, the plurality of turbidity measurements of the PD effluent of the PD patient, the plurality of UFV measurements of the PD patient, and the plurality of PD prescriptions of the patient;
- and
- access a new turbidity measurement of the PD effluent of the patient during a subsequent PD treatment, and based on the correlation, determining a new hydration status of the patient based on the new turbidity measurement of the PD effluent at the time of the subsequent PD treatment.
