Cardiac output monitor using fuzzy logic blood pressure analysis |
摘要 |
A method of monitoring cardiac output. The method uses a blood pressure waveform as input. The waveform is digitized and various blood pressure features are extracted. The features are used as inputs to a fuzzy logic model, where each input is fuzzified by determining its degree of confidence as a member of one or more fuzzy membership regions. A rule base is applied to the defuzzified inputs to obtain a fuzzy stroke volume index. This output is defuzzied and used to calculate cardiac output.
