May support Liljestrand-Zander for waveform CO estimation in ICU; hypothesis-generating and requires prospective validation before practice change.
Do investigational algorithms estimating cardiac output from arterial blood pressure waveforms provide accurate estimates compared to thermodilution in ICU patients?
The Liljestrand and Zander algorithm provides a better quantitative estimate of cardiac output from arterial blood pressure waveforms than mean arterial pressure alone in ICU patients.
