First Claim
Patent Images
1. A system for hemodynamic waveform data trend analysis, the system comprising:
- means for generating hemodynamic pressure waveform data that corresponds to sensed hemodynamic pressure over time;
means for analyzing the hemodynamic pressure waveform data to determine hemodynamic waveform parameters, including a systolic pressure and a diastolic pressure for a cardiovascular pulse cycle; and
means for identifying multiple types of artifactual data in a series of hemodynamic waveforms based upon hemodynamic waveforms in the series and for generating trend data using hemodynamic waveforms containing the identified types of artifactual data, using only those of the hemodynamic parameters that are unaffected by the identified artifactual data.
