Abstract :
A simple and effective method of displaying blood pressure measurement from photoplethysmography has been developed. The method is developed to be incorporated as noninvasive monitoring of blood pressure from a patient in a intensive care unit. This implementation includes finger tip pulseoximetry probe, differential amplifier, data acquisition card, software filtering, amplification and blood pressure measurement from pulse transit time calculation continuously by microcomputer correlation of pulse transit time to blood pressure. It is expected that the method will be incorporated to a low cost portable personal computer based ICU monitoring system that will also display temperature, pulse rate and ECG of the patient continuously in future.
