Hypothesis-generating for waveform-based continuous cardiac output monitoring; prospective validation required before clinical adoption.
Does continuous cardiac output monitoring by peripheral ABP waveform analysis accurately measure relative cardiac output changes compared to thermodilution and Doppler ultrasound in humans?
A novel mathematical technique for continuous cardiac output monitoring using peripheral arterial blood pressure waveforms showed approximately 15% error compared to standard invasive and noninvasive methods, suggesting potential utility for acute care monitoring.
