Why the study?
Does arterial pulse pressure waveform analysis (FloTrac/Vigileo) accurately measure cardiac output compared to the lithium dilution method in anesthetized dogs?
Does arterial pulse pressure waveform analysis (FloTrac/Vigileo) accurately measure cardiac output compared to the lithium dilution method in anesthetized dogs?
The FloTrac/Vigileo system overestimates cardiac output and has a high relative error compared to lithium dilution, rendering it unreliable for hemodynamic monitoring in dogs.
Answers are grounded in this paper and cite their sources.
Unacceptable agreement in this canine model; leaves open the validity of pulse contour analysis for veterinary hemodynamic monitoring.
