Comparison of cardiac output determined by arterial pulse pressure waveform analysis method (FloTrac/Vigileo) versus lithium dilution method in anesthetized dogs

Abstract

The FloTrac/Vigileo overestimated CO values compared with LiDCO and the relative error was high, which makes this method unreliable for use in dogs.

Comparison of thermodilution, lithium dilution, and pulse contour analysis for the measurement of cardiac output in 3 different hemodynamic states in dogs

“…However, the numerous complications associated with the technique prompted the development of new, less‐invasive CO monitors . This interest has transferred to veterinary medicine, and several studies conducted over the past few years using different methodologies to measure CO have reported different results . Lithium dilution LiDCO, one of the first minimally invasive monitors used to measure CO in veterinary patients, is considered to be an accurate monitor with good concordance with the PAC‐TD method .…”

[13][14][15]38 PiCCO TD was introduced more recently, and therefore, few papers have considered its usefulness in veterinary medicine.…”

A pilot study evaluating adaptive closed‐loop fluid resuscitation during states of absolute and relative hypovolemia in dogs

“…We employed the Vigileo Flo‐Trac sensor to estimate SVV. Although this system has been shown to overestimate CO in isoflurane anesthetized dogs due to a higher degree of dependence on arterial blood pressure, it has been shown to be a sensitive indicator of dynamic circulating blood volume changes …”

Evaluation of the non-calibrated pulse contour cardiac output monitor FloTrac/Vigileo against thermodilution in standing horses

“…) and LiDCO (Valverde et al. ) to be insufficient. The arterial pulse contour per se does not differ among different mammal species, which motivated the authors of these studies to evaluate FloTrac in non‐human species.…”
