Many acute and chronic medical and surgical conditions require health care providers to make accurate assessments of the volume of blood in a patient’s circulatory system. But the current non-invasive and invasive standards of care for determining this are not always accurate and can put the patient at risk.
The University of Michigan has developed Dynamic Respiratory Impedance Volume Evaluation (DRIVE), a non-invasive method that monitors a patient’s circulating blood volume without the risks of a more invasive treatment. DRIVE assesses functional volume by utilizing changes in limb blood volume produced by breathing as measured by changes in impedance of the limb.
DRIVE is supported by a small wearable, wireless device that provides personalized, continuous, and easily interpreted diagnostic data for a variety of managed-care environments, from emergency room to clinic to home.
DRIVE will provide accurate, continuous, easily interpreted information useful for many levels of intravascular volume management care from home and clinic, to ambulance, emergency department, ICU, and general wards.
DRIVE makes accurate, continuous, and non-invasive assessments of a patient’s circulating volume status, whether the patient is hypovolemic or hypervolemic and whether the patient will respond favorably to addition or removal of intravenous fluids.
