Methods of Calibrating a Blood Flow Monitoring Device, Methods of Monitoring Blood Flow, and Blood Flow Monitoring Systems
An example method of calibrating a blood flow monitoring device includes positioning a remote device and a blood flow monitor within physical proximity of one another, placing the remote device in a calibration mode such that a microphone of the remote device is active and can receive Doppler sounds emitted by a speaker of the blood flow monitor; emitting Doppler sounds through the speaker of the blood flow monitor; receiving the Doppler sounds as received Doppler sounds using the microphone of the remote device; emitting the received Doppler sounds through a speaker of the remote device as remote device sounds; receiving the remote device sounds using the microphone of the remote device; identifying any differences between the received Doppler sounds and the received remote device sounds; and calibrating the remote device based on the identified differences between the received Doppler sounds and the received remote device sounds.

9 . A method of calibrating a blood flow monitoring device comprising:
placing a tissue flap at a point of treatment, the tissue flap including a section of tissue that includes a blood vessel;
attaching a sensor to the tissue flap to monitor blood flow through the blood vessel, the sensor attached to the tissue flap such that it contacts the blood vessel;
attaching the sensor to a blood flow monitor having a speaker and configured to emit Doppler sounds;
activating the blood flow monitor such that the blood flow monitor is monitoring blood flow through the blood vessel;
positioning a remote device and the blood flow monitor within physical proximity of one another, the remote device having a microphone and a speaker;
placing the remote device in a calibration mode such that the microphone of the remote device is active and can receive Doppler sounds relating to the blood flow through the blood vessel emitted by the speaker of the blood flow monitor;
emitting Doppler sounds relating to the blood flow through the blood vessel through the speaker of the blood flow monitor;
receiving the Doppler sounds relating to the blood flow through the blood vessel as received Doppler sounds using the microphone of the remote device;
emitting the received Doppler sounds through the speaker of the remote device as remote device sounds;
receiving the remote device sounds using the microphone of the remote device;
identifying any differences between the received Doppler sounds and the received remote device sounds; and
calibrating the remote device based on the identified differences between the received Doppler sounds and the received remote device sounds.

11 . The method of claim 9 , wherein the blood vessel is a vein.
12 . The method of claim 9 , wherein the blood vessel is an artery.
13 . The method of claim 9 , wherein receiving the Doppler sounds relating to the blood flow through the blood vessel as received Doppler sounds using the microphone of the remote device is accomplished such that the received Doppler sounds are saved locally to the remote device.
14 . The method of claim 9 , wherein receiving the remote device sounds using the microphone of the remote device is accomplished such that the received remote device sounds are saved locally to the remote device.
15 . The method of claim 9 , wherein the remote device has a visual display field; and
wherein the blood flow monitor has a visual display field.
16 . The method of claim 15 , further comprising displaying data relating to the blood flow through the blood vessel on the visual display field of the blood flow monitor; and
further comprising displaying data relating to the blood flow through the blood vessel on the visual display field of the remote device.
17 . A method of monitoring blood flow comprising:
calibrating the sound quality of a remote device having a speaker and a microphone;
placing a tissue flap at a point of treatment, the tissue flap including a section of tissue that includes a blood vessel;
attaching a sensor to the tissue flap to monitor blood flow through the blood vessel, the sensor attached to the tissue flap such that it contacts the blood vessel;
attaching the sensor to a blood flow monitor having a speaker and configured to emit Doppler sounds;
activating the blood flow monitor such that the blood flow monitor is monitoring blood flow through the blood vessel;
monitoring the blood flow through the blood vessel over a period of time;
positioning the remote device at a first location that is different from a second location at which the blood flow monitor is disposed;
emitting Doppler sounds relating to the blood flow through the blood vessel through the speaker of the remote device; and
determining if the Doppler sounds relating to the blood flow through the blood vessel indicate intervention is required, if intervention is required the method further comprises performing treatment to accomplish the intervention, if intervention is not required the method further comprises removing the sensor from the tissue flap.
