Brachial Artery Pressure Waveform Analysis

Continuous tracking of the brachial artery pressure waveform was obtained with standard methodology (41 (link)), and the average of 2 or more recorded profiles was used for PWA as previously reported (13 (link)). The AIx was calculated from the aortic pressure waveform as the difference in height between the first and the second systolic peaks that were expressed as a percentage of the pulse pressure. The intraobserver coefficient of variation of the AIx was 8.4%.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
