HemaMetrics

HemaMetrics is a medical technology company specializing in non-invasive blood volume monitoring solutions for patients undergoing hemodialysis. The company's flagship product, the Crit-Line monitor, provides real-time measurements of hematocrit, oxygen saturation, and percent change in blood volume, allowing clinicians to manage fluid removal more effectively. By providing continuous data during treatment, HemaMetrics' technology helps reduce the risk of intradialytic hypotension and improves overall patient outcomes in renal care. The company was acquired by Fresenius Medical Care in 2003 to integrate its monitoring capabilities into their global dialysis portfolio. Today, the Crit-Line technology remains a critical tool for fluid management in dialysis clinics worldwide. It utilizes photo-optical spectrometry to provide a profile of the patient's vascular refill rate.
