About
The purpose of this study is to measure the fluid changes in the body using a device called the µ-Cor System, an investigational device. The µ-Cor System will record the fluid changes in the body, as well as ECG (electrocardiogram or an electrical tracing of your heart rhythm) heart rate, breathing rate, posture and activity at regular intervals.
The information collected by the µ-Cor System will then be compared to the actual fluid removed through dialysis and to the information collected by an FDA (Food and Drug Administration) cleared device called ZOE (NonInvasive Medical Technologies), a monitor which also measures the fluid changes in the body.
The objectives of this study are to document any differences in measurement of thoracic impedance obtained from the µ-Cor System and the ZOE system. Thoracic impedance is a measure of the electrical activity in the chest that varies with changes in body size and composition, fluid volume, breathing status and other variables.
Measurements of the amount of fluid removed during dialysis will also be compared between the µ-Cor System, the ZOE system and the actual fluid removed.
The ability of the µ-Cor System to measure thoracic impedance will be tested by placing the device randomly at one of two locations:
Both the µ-Cor System and the ZOE System will be worn simultaneously during one dialysis session. The ZOE system device is placed on the chest- 2 points: 1 at the base of your neck and 1 in your mid chest.
Full description
The µ-Cor System is intended to record, store, transmit, and display the following physiological data to medical professionals: thoracic impedance, ECG, heart rate, respiration rate, activity and posture.
The µ-Cor System is indicated for patients who are 21 years of age or older who:
Objectives:
Subject population:
Forty patients undergoing hemodialysis (n = 40) in 2 study arms with at least 50% enrollment of patients diagnosed with congestive heart failure (CHF) in each arm:
Patients will wear the µ-Cor device and will be connected to the ZOE monitor during one hemodialysis session in the clinic. Patients will be randomly allocated to Study Arm 1 or Study Arm 2, with randomization stratified by CHF status (CHF or non-CHF). During the hemodialysis session, the patient will wear 1 µ-Cor device and will be connected simultaneously to 1 ZOE monitor (via 2 ZOE electrodes) for comparative measurements and UFV correlation, from at least 15 minutes before the start of dialysis to at least 15 minutes after the end of the dialysis session. The µ-Cor will record measurements during the dialysis session, including at least the 15 minutes before and 15 minutes after the session. ZOE (Z0) values will be measured every 6 minutes (± 1 minute) during the dialysis session. ZOE (Z0) values also will be measured every 3 minutes (± 1 minute) before and after the session, for a minimum of 5 measurements. The UFV during the course of hemodialysis will be measured by automated readings provided by the dialysis machine every 6 minutes (± 1 minute). 10. Any IV infusions administered, oral fluid or solid intake, and urine output during the course of hemodialysis will be recorded. Weight, blood pressure, and heart rate will be recorded before and after the dialysis session.The patient's involvement in the study ends after the completion of all procedures planned for the hemodialysis session.
