Trial Outcomes & Findings for Clinical Evaluation of the CM-1500 During Apheresis Blood Donation (NCT NCT05012462)

NCT ID: NCT05012462

Last Updated: 2024-12-06

Results Overview

The objective of the study is to characterize changes in the Relative Index (RI) as a representation of its associated parameters during apheresis. This was measured by averaging the RI values after the procedure. Changes in parameters from their baseline can be used as an indicator of potential change in fluid status. This change may be reflected in the RI since it is a summated value (weighted summation of percent change) combining the changes of the parameters into a single value. In the case of fluid loss such as apheresis the RI value may decrease as a result of changes in the parameters which can change in response to fluid status change. The RI is a unitless value with no set min. or max. Within the context of this trial trying to evaluate the RI, a decrease from 100 was considered a good outcome. However, in clinical use, the RI should not be used as an indicator of patient status, instead it could be used to monitor trending of patient parameters relative to their baseline.

Measure
Apheresis Platelet Donation: CM-1500
The subjects will be connected to the CM-1500 during apheresis platelet donation CM-1500: The CM-1500 is a U.S. FDA cleared non-invasive monitoring device that simultaneously monitors five (5) parameters of a patient's body. A combination of these parameters is represented by a single number known as the Relative Index value.
Apheresis Platelet Donation: CM-1600
The subjects will be connected to the CM-1600 during apheresis platelet donation CM-1600: The CM-1500 is a U.S. FDA cleared non-invasive monitoring device that simultaneously monitors Bioelectrical Impedance, Photoplethysmography (PPG) Amplitude, ECG Amplitude and Skin Temperature. A combination of these parameters is represented by a single number known as the Relative Index value.

Timeframe: Duration of apheresis procedure (e.g., 2 - 3hrs)
