Sphygmocor is the tonometry based instrument which is used to record generally radial pulse waves and then calculating various variables like Augmentation Index, SEVR etc. It is also used to calculate pulse wave velocity. I have downloaded 2-3 papers on same research which have calculated pulse wave velocity in their studies and ultimately got information of arterial stiffness in those studies. however calculating pulse wave velocity by methods elaborated in these studies is cumbersome as it requires recording pulse of poplitial artery whose recording is again a cumbersome process. Can anyone suggest easy method to calculate pulse wave velocity using this instrument so that i can comment on arterial stiffness in study population.
Of course yes!.
You can use the PWV oscillometric method using the mobil-O-graph device. It is a very simple and accurate method.

Thank for ur response. Didn't know about this method. Will read about it.
Clasical pulse wave velocity (PWV) estimation in the elastic arteries is a measuring of the wave propagation alongside of aorta: from carotid to femoral artery. When you evaluate PWV in muscular-type arteries you use a sector from the carotid to the radial artery. In Sphygmocor device the software evaluates the delay of the pulse wave onset in each site of investigation (carotid, femoral and radial artery) to R wave on ECG. If the heart rate is the same (constant) the software calculates PWV. The main problem of this device is the requirement of constant heart rate. In other type of devices (Complior, etc.) you can record pulse wave from two or three sites simultaneously and it could be more accurate PWV estimation in comparison with Sphygmocor. However, all these devices are recommended for PWV evaluation.
