A blood flow monitor with a visual display. The monitor may include a probe monitoring circuit configured to be associated with a blood vessel. The probe monitoring circuit may transmit a burst signal and receive a reflected signal, where a frequency shift in the reflected signal represents a flow rate associated with the blood vessel. A mixer may be provided in electrical communication with the probe. A signal processing circuit in electrical communication with the output of the mixer may be configured to drive the visual display with a signal representing the flow rate associated with the blood vessel.
