Abstract: A system and method for measuring blood pressure that allows for both coupling of fiber optic pressure sensors with a standard patient care monitor (PCM) and vascular assessment using statistical analysis of pressure wave data. The disclosure has a blood pressure monitor (BPM) system that calibrates and compensates blood pressure data for display on a standard PCM using analog-to-digital-to-analog conversion and Wheatstone Bridge emulation. The BPM can also analyze collected pressure wave data using various statistical methods. Using fast Fourier transform (FFT), pressure wave data can be used in vascular assessments to image or otherwise graphically display key vessel attributes. This permits localized intervention and detection of physiologic attributes of vessels prior to the grossly evident anatomical interruption.

The first photodetector receives the infrared wavelength reflected from the patient as a contrasted image of subcutaneous veins, and surface reflection noise due to skin surface topology, and outputs a first signal representing that contrasted image of subcutaneous veins and noise due to skin surface topology. The second photo detector receives the human-visible wavelength reflected from the skin surface and outputs a second signal representing a contrasted image of the topology. The second signal is subtracted from the first signal to remove the noise, permitting projection of a surface-noise-free vein image onto the skin surface.
