Why to Choose the Volume Clamp Method for cNIBP over Other Methods
Summary
Although radial artery Applanation Tonometry has a sound physiologic basis and hence potential in the arena of clinical medicine, published treatment and outcome data for it are less complete than for brachial blood pressure5. In summary, therefore, the two biggest practical challenges to measure cNIBP using PTT based technique are the need for frequent calibration as well as the susceptibility to motion artifacts of electrophysiological and PPG signals in daily life. To date, the vascular unloading concept has been the most successful and validated technique for cNIBP monitoring, bridging the gap between conventional upper arm cuff BP measurements and arterial lines.
