Abstract :Along with the development of non-invasive techniques for the high accuracy measurement of blood pressure on the finger, the investigation of finger pulse volume (PV) variability has been attracted considerable interest. Modified normalized pulse volume (mNPV) has the potential to be a practical index for the determination method of mean arterial pressure (MAP) based on the volume clamp method due to its very sensitive to vasoconstrictor stimuli on the finger. However, MAP derived by mNPV has not yet been investigated. Therefore, we compared MAP measured by sphygmomanometer as a reference, with MAP derived by the PV and mNPV using the developed prototype system during baseline in ten young subjects. The results gave mean differences in Bland-Altman plots between the measured MAP and MAP derived by PV and mNPV of 1.86 ± 6.49 (standard deviation) and -2.54 ± 8.12, respectively. mNPV is discussed in terms of the availability for determination of MAP based on VCM. In conclusion, mNPV is a valid approach, which might be useful for the calibration index of MAP derived by PV.
