Resumen:
The viscoelastic arterial wall transfer function was determined noninvasively based on pressure and diameter signals of the finger artery measured sequentially using the volume compensation method. The uncompensated arterial diameter variations were converted to pressure using the estimated transfer function parameters. This pressure signal was negligible compared to measured pressure except at systole when reduction of 9 mmHg was achieved, thus correcting the volume compensation method?s error. To validate the method, central aortic pressure should be reconstructed from finger artery measurements and compared to invasive methods.
