Abstract

An automated sphygmomanometer which utilizes quality algorithms to stop any further analysis at various points during a blood pressure determination because of corrupted data. If the data is so corrupted that giving blood pressure numbers is inappropriate, this is recognized and the determination stopped. The quality algorithms make a decision to get more data with the hope of improving the blood pressure estimation. The request for data occurs both before and/or after a curve fitting process, if such a process is utilized. Some information is also provided to the cuff pressure control function about which pressure levels would be best for gathering the additional data. The quality algorithms are also used to make a decision as to whether it is appropriate to publish the blood pressure values obtained. Control parameters (weights) may be set within the blood pressure algorithm to help with other aspects of the NIBP algorithm and improve the quality of the final published numbers. The quality algorithms may also help the system to decide whether to publish any warnings when significant artifact is present.
