Abstract:
Intermittent measurement of blood pressure (BP) is frequently performed in newborn babies under intensive care using an inflatable cuff encircling either the arm or leg. This paper describes work aimed at achieving continuous beat-by-beat measurement of the arterial pressure waveform by means of a finger cuff, the pressure of which is controlled by a feedback arrangement utilising a photoplethysmograph. Preliminary results are encouraging, but improvements to cuff design are still needed.
