Pulse-Pressure Estimation

Pulse Pressure Variation Estimation Based on Rank-Order Filters

We describe a methodology to estimate the pulse pressure variation ∆Pp index from the arterial blood pressure (ABP) signal alone. This eliminates the need for simultaneously acquiring and monitoring airway pressure. The technique uses nonlinear rank-order filters to demodulate the respiratory component modulating the ABP signal. Furthermore, we present a simple mathematical model that can be us...

Estimation of Blood Pressure Using Pulse Transit Time

Pulse pressure and microvessels.

Determinants of pulse pressure.

We have searched to define the major arterial parameters that determine aortic systolic (Ps) and diastolic (Pd) pressure in the dog. Measured aortic flows were used as input to the 2-element windkessel model of the arterial system, with peripheral resistance calculated as mean pressure divided by mean flow and total arterial compliance calculated from the decay time in diastole. The windkessel ...

Tire Inflation Pressure Estimation Using Identification Techniques

In this research study, one of the most crucial automotive engineering problems is intended to be solved. The necessity of tire pressure monitoring system is beyond doubt. Such systems are now provided relying on expensive sensors. In this study an indirect tire pressure monitoring system is proposed, utilizing identification techniques, which will reduce the cost of monitoring considerably in ...
