Variability in mean arterial pressure and diastolic blood pressure from central to peripheral large arteries: relevance to arterial physiology and estimated central blood pressure

Background: Mean arterial pressure (MAP) and diastolic blood pressure (DBP) are thought to consistently decline approximately 1-3 mmHg from the aorta to peripheral large arteries, thus providing a small pressure gradient to aid blood flow. The magnitude of this gradient is important for correct waveform calibration and central BP estimation. However, there is little invasive data determining the variability in MAP and DBP from central to peripheral arteries, which was the goal of this study.
