Abstract:Objective To evaluate the accuracy of a new cardiac output monitor (FloTrac/Vigileo), originally designed for humans, in dogs. This pulse contour cardiac output monitoring system cannot be calibrated and measures cardiac output (Q̇t) from a standard arterial catheter.
Study design Prospective experimental trial.
Animals Eight adult Beagle dogs weighing 13.1 (9.8–17.1) kg [median (range)].
Methods Anaesthesia in the dogs was maintained using isoflurane. A pulmonary artery catheter and a metatarsal arterial … Show more
“…In agreement with the current study, previous findings in dogs have also shown the accuracy and precision of FloTrac V1.10 with TD (Bektas et al. ) and LiDCO (Valverde et al. ) to be insufficient.…”

“…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 …”
Closed-loop fluid administration based on IV fluid distribution and compartmental dynamical systems can be used to provide goal directed fluid therapy during absolute or relative hypovolemia in mechanically ventilated isoflurane anesthetized dogs.
“…Unfortunately, this requirement has been overlooked in many cases, and still many investigators use the classical Bland‐Altman plot for replicate measurements (Bektas et al. ; Garofalo et al. ; Seliskar et al.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
