Flow Restriction Principle approach to noninvasive arterial blood pressure
determination -- a method for highly accurate waveform recording.
For Illustration of Principle, click
The Flow Restriction Principle for accurate recording of the blood
pressure waveform was first described in 1981 (
Aaslid R, Brubakk AO. Accuracy of an ultrasound Doppler servo method for
noninvasive determination of instantaneous and mean arterial blood pressure.
Circulation. 1981;64:753-9 )
An animated illustration of this method using a complex mathematical model can
be found on a separate page. Size of Java applet
download only about 32kB. (Your browser must be Java applet enabled to perform
solution of the differential equations. -- Free Java Runtime plugin is
available from Sun Microsystems)
recommended for Internet Explorer or Opera browsers if the current Java Applet
does not run on your system).
