A system and method of enhancing a blood pressure signal is disclosed. The volume of an artery in a finger is measured by a photo-plesthysmographic (PPG) system, which produces a PPG signal. This PPG system is placed inside a cuff, and the cuff pressure is controlled by the PPG signal. The portion or component of the PPG signal having a frequency higher than a predefined threshold frequency is then modified or enhanced, such as by multiplying the high frequency component by a calibration factor. A blood pressure signal is then calculated using the cuff pressure and the modified PPG signal. A blood pressure contour curve may then be generated, and a variety of parameters may be calculated using the curve.

Apparatus and method for enhancing and analyzing signals from a continuous non-invasive blood pressure device

A sensor system for continuous non-invasive arterial blood pressure (CNAP) is provided. The CNAP-sensor comprises of a base portion and a detachable and disposable portion. The base portion is connected to a control system. The disposable portion is for attachment to a human body part. The CNAP-sensor system includes a photo-plethysmographic (PPG) system having at least one light source, at least one light detector, electrical supplies, light coupling systems, one or more connectors, and a cuff including air supplies.

Disposable and detachable sensor for continuous non-invasive arterial blood pressure monitoring

A system and method of digital control for a blood pressure measurement system is provided. According to at least one embodiment, a photo-plethysmographic (PPG) system produces a frequency signal that corresponds to the measured light in the PPG system. Such light may be indicative of blood volume in a vein or artery. The frequency signal may be used to control one or more pressure valves of the system in order to measure blood pressure and hold the frequency signal constant.
