This is direct measurement and has been considered as the most accurate method. To perform the measurement, a catheter must be inserted into the aortic root from brachial or femoral artery, which is obviously an invasive method and could result in complications.

Non-invasive method – BPro® + A-PULSE CASP®

HealthSTATS (HS) invented a device named BPro which is able to capture radial pressure waveforms. Furthermore, HS developed a proprietary formula, which was built in a commercial software A-PULSE CASP®, to derive CASP from the calibrated radial pressure waveform.
