Estimation of vascular resistance by analysis of blood pressure waveforms

1. A Novel Algorithm to Continuously Monitor Change of Total Peripheral Resistance using Peripheral Arterial Blood Pressure Values for Prediction of Orthostatic Intolerance Tatsuya Arai 1 , Kichang Lee 2 , and Richard J.

2. Model and Hypothesis End diastolic pressure, beat duration, time from the onset to the peak of systole, and mean arterial pressure are relatively insensitive to distortion TPR AC Flow BP Waveform distortion

3. Algorithm Aortic Compliance (AC) Vascular Resistance (TPR)
