Non invasive assessment of carotid and femoral arterial pressure using B-mode ultrasound diameter waveforms.

Mostrar todas las versiones(2)

Non invasive local arterial blood pressure measurement has become a challenge over recent years. The aim of this study was to evaluate in a general population the validity of an alternative method to assess systolic local arterial blood pressure, from the analysis of B-mode diameter waveforms, and t...

The aim of this study was to evaluate in a general population the validity of an alternative method to assess systolic local arterial blood pressure, from the analysis of B-mode diameter waveforms, and to estimate the accuracy when compared to carotid and femoral arterial tonometry. In 190 asymptomatic subjects (51±11 years, range: 24-73; pulse pressure: 51±11 mmHg, range: 31-93) systolic arterial pressure was obtained at the left carotid and left femoral artery by applanation tonometry (SBP(Car)_Ton and SBP(Fem)_Ton) and by automatic analysis of B-mode echographic images, calibrated using an iterative exponential model.
