Method for respiratory tidal volume measurement |
摘要 |
A method obtains physiologic parameter information of an animal or human, such as respiratory tidal volume, from a blood pressure signal from an implanted blood pressure sensor in the animal or human. Specifically, the blood pressure signal is externally signal processed to develop an amplitude versus time waveform. A sequence of selected blood pressure features derived from individual cardiac cycles of the amplitude versus time waveform over a selected time interval are extracted from the developed amplitude versus time waveform. A mathematical model is fitted to the extracted sequence of selected blood pressure features to yield a fitted mathematical model. Blood pressure information indicative of a magnitude of the change in blood pressure that occurs over a respiratory cycle is computed from the fitted mathematical model. The physiologic parameter respiratory tidal volume, is then computed as a function of a correction factor and the blood pressure information.
