Key result
A novel technique for continuously monitoring cardiac output via mathematical analysis of peripheral arterial blood pressure waveforms yielded an overall error of 14.6% in acute swine experiments.
Why the study?
Does mathematical analysis of peripheral arterial blood pressure waveforms accurately estimate cardiac output compared to aortic flow probes in a swine model?

Mukkamala et al. (2006) studied this question. Mathematical analysis of peripheral arterial blood pressure waveform vs. Aortic flow probe CO was evaluated on Overall CO error. A novel technique for continuously monitoring cardiac output via mathematical analysis of peripheral arterial blood pressure waveforms yielded an overall error of 14.6% in acute swine experiments.
