Not Applicable

Completed

• Conditions: Fluid Loss; Dialysis
• Interventions: Device: CM-1500

• Registration Number: NCT05125848
• Lead Sponsor: Zynex Monitoring Solutions

Brief Summary

The study is a prospective, single-arm, non-randomized, non-blinded, non-controlled, non-significant risk, single center study enrolling up to 20 subjects consented to undergo a hemodialysis session as a part of their standard prescribed treatment plan. Subjects will consent to undergo non-invasive monitoring with the CM-1500 during three (3) separate sequential hemodialysis sessions.

Arm && Interventions

Group	Intervention	Description
Hemodialysis Single Group Assignment	CM-1500	All enrolled subjects will be connected to the CM-1500 for monitoring during their hemodialysis session

Primary Outcome Measures

Name	Time	Method
Average Relative Index Value Following a Hemodialysis Procedure	Duration of post-hemodialysis recovery period (10-minutes)	The primary objective is to characterize the average CM-1500 Relative Index (RI) following a hemodialysis procedure. The RI is an investigational value which utilizes proprietary algorithms to combine the changes of multiple measured parameters (utilizing a weighted summation of percent change values) which are indicative of relative changes in fluid volume in adult patients into a single value. The RI is a unitless value with no set minimum or maximum, where 100 is a patient's baseline. Based on the nature of the RI itself, a direct interpretation of a positive or negative outcome cannot be derived from the absolute value, instead it could be used to monitor trending of a patient's parameters relative to their baseline. The average RI after dialysis procedure was calculated by averaging all measured RI values for all subject sessions (3 sessions per subject, totaling 45 sessions) during the 10-min post-hemodialysis recovery period.

Secondary Outcome Measures

Name	Time	Method
Mean Intersubject Variability (Standard Deviation) in Relative Index (RI) During Hemodialysis Sessions	Duration of standard dialysis procedure (Range: 131 to 241 minutes)	The secondary objective is to characterize intersubject variability in RI changes across 3 hemodialysis sessions. Intersubject variability was calculated by finding the mean and standard deviation of the variability (standard deviation) from the mean RI values (1 value per sec) for each hemodialysis session monitoring period (3 sessions x 15 subjects = 45 individual monitoring sessions). The RI is an investigational value which utilizes proprietary algorithms to combine the changes of multiple measured parameters (utilizing a weighted summation of percent change values) which are indicative of relative changes in fluid volume in adult patients into a single value. The RI is a unitless value with no set min. or max., where 100 is a patient's baseline. Based on the nature of the RI itself, a direct interpretation of a positive or negative outcome cannot be derived from the absolute value, instead it could be used to monitor trending of a patient's parameters relative to their baseline.
Mean Intrasubject Variability (Standard Deviation) in Relative Index (RI) During Hemodialysis Sessions	Duration of standard dialysis procedure (Range: 131 to 241 minutes)	The secondary objective is to characterize intrasubject variability in RI changes across 3 hemodialysis sessions. Cohort intrasubject variability was calculated by averaging individual subject standard deviations across enrollments. Variability for each subject is calculated by finding the RI mean and standard deviation for all RI values (1 per sec) during all 3 monitoring sessions. The RI is an investigational value which utilizes proprietary algorithms to combine the changes of multiple measured parameters (utilizing a weighted summation of percent change values) which are indicative of relative changes in fluid volume in adult patients into a single value. The RI is a unitless value with no set min. or max. where 100 is a patient's baseline. Based on the nature of the RI itself, a direct interpretation of a positive or negative outcome cannot be derived from the absolute value, instead it could be used to monitor trending of a patient's parameters relative to their baseline.
