Zynex, Inc. announced that it has submitted a 510(k) application to the U.S. Food and Drug Administration ("FDA") for the CM-1600, its next generation fluid monitoring system. The Zynex Fluid Monitoring System (CM-1500) is a 100% non-invasive solution for monitoring fluid changes throughout patient care environments. Patient fluid status is determined using an algorithm that combines the trends of several physiological parameters to generate a single Relative IndexTM (RI) value, allowing for fast interpretation of changes in fluid volume.
