When a patient has a flap (tissue moved from one part of body to another), such as when I make a breast from the abdomen or inner thigh, the blood flow within it is monitored with the use of a doppler device. The Doppler proble is applied to the skin overlying the blood vessel and the signal is determined by a sound.
The work of one man has resulted in the Doppler effect being used in many everyday things we take for granted- sirens, satellite communication, fetal heart monitoring, police radars and monitoring blood flow in medicine.
The Doppler signal is the change in frequency of a sound wave for an observer, moving relative to its source, named after an Austrian physicist Christian Doppler, in 1842. It is commonly heard when a vehicle with a siren approaches, passes and recedes. He described the effect at the age of 38 , published many articles as a Professor and then died pre-maturely at the age of 49 from lung disease.
