Two commonly estimating blood pressure (BP) models. SBP: systolic blood pressure, DBP: diastolic blood pressure, MK-BH: combination of the Bramwell–Hill and Moens–Korteweg equations, dMK-BH: development model of MK-BH.

Models	SBP	DBP
MK-BH [3]	$SB{P}_0-\frac{2}{\gamma \cdot PT{T}_0}·\left(PTT-PT{T}_0\right)-\frac{2}{{\mathsf{\gamma }*\mathrm{PAT}}_0}*\left(\mathrm{PAT}-{\mathrm{PAT}}_0\right)$	$SBP-P{P}_0·{\left(\frac{PT{T}_0}{PTT}\right)}^2$
dMK-BH [17]	$DBP+P{P}_0·{\left(\frac{PT{T}_0}{PTT}\right)}^2$	$MB{P}_0+\frac{2}{\gamma }ln\left(\frac{PT{T}_0}{PTT}\right)-\frac{P{P}_0}{3}·{\left(\frac{PT{T}_0}{PTT}\right)}^2$

Note 1: $\mathsf{\gamma }$ denotes a vascular information parameter. Note 2: $P{P}_0=SB{P}_0-DB{P}_0,MB{P}_0=(P{P}_0+DB{P}_0)/3$ , PP—pulse pressure, MBP—mean BP. Note 3:$SB{P}_0,DB{P}_0, PT{T}_0, {\mathrm{SBP}}_0,{\mathrm{DBP}}_0,{\mathrm{PP}}_0$ are determined at the beginning of monitoring by calibration using an additional cuff-type BP monitor device.
