Overcoming the Limitations of Conventional Hemodynamic Monitoring

The First Noninvasive Device to Assess Blood Circulation

Detect Early Signs of or ongoing signs of Hemorrhage Using a new Technology

Welcome to the MGI Medical website.

MGI Medical has developed the first monitor for noninvasive, continuous assessment of peripheral blood flow. It was developed for the early detection of blood loss and heart failure. It may have other medical applications as well.

A Note from Dr. Marks, Inventor of the MGI Pulse Flowmeter:

"When I was in medical school, I observed a patient bleed to death overnight from an internal occult hemorrhage. This occurred in a university hospital and after only a minor, elective vascular procedure. I was horrified that we did not have a monitor that could prevent this situation from occurring."

"As we know, conventional means for detection of occult hemorrhage (hypotension, decreased urine output, etc.) are, at best, lagging indicators. I have devoted a substantial part of my career to looking for ways to assess peripheral flow as an early warning sign for blood loss. This has resulted in the Pulse Flowmeter, which can detect the loss of a single unit of blood in blood donors with no change in BP or heart rate. Preliminary investigations suggest that the Pulse Flowmeter may be useful for a variety of applications where peripheral flow and resistance information is desirable."

The First Noninvasive, Continuous, Quantitative Peripheral Blood Flow Monitor

Our Company

MGI MEDICAL was formed to develop and bring to market the Pulse Flowmeter, a new noninvasive potentially transformative medical device. The Pulse Flowmeter was specifically developed for the early detection of blood loss. It provides the anesthesiologist, intensivist, or cardiologist with ongoing quantitative measurement of blood flow to the vascular beds of a patient’s extremities. As is well known by physicians who care for unstable patients, blood pressure provides only limited information about pump function and volume status. Because systemic blood pressure is maintained at the expense of peripheral blood flow, when a patient is losing blood or experiencing pump failure, blood pressure is a lagging indicator. In the extreme case, shock ensues when the blood flow is insufficient to meet metabolic demands. The Pulse Flowmeter looks directly at the peripheral flow and, in combination with blood pressure, provides real-time, continuous measurement of peripheral vascular resistance.

Knowledge of peripheral blood flow and peripheral vascular resistance is useful for the management of a wide variety of medical conditions and procedures. The Pulse Flowmeter has been formally and informally tested in a variety of locations and for a variety of applications.
