Why the study?
Does a multivariate statistical model improve stroke volume estimation from aortic pressure waveforms compared to pulse-contour models in conscious rats?
Does a multivariate statistical model improve stroke volume estimation from aortic pressure waveforms compared to pulse-contour models in conscious rats?
A multivariate statistical model using eight parameters from the aortic waveform provides more reliable and precise beat-to-beat stroke volume estimation than pulse-contour models in conscious rats.

Statistical models outperform pulse-contour for SV estimation in rats; leaves open human translation and requires prospective validation.
