“…Moreover, it performs better when the dogs suffer from acute absolute hypovolemia. In clinical scenarios, clinicians may accept a CO method that may not provide highly accurate absolute measurements but is still able to reliably detect trends whenever CO values change [ 22 , 23 ]. They may also prefer less invasive techniques rather than dealing with PATD’s potential serious complications and consequent poor outcomes.…”

“…The acceptable performance and accuracy of EC for conducting advanced hemodynamic monitoring has been reported in critically ill adult human patients [ 13 ], women receiving spinal anesthesia for cesarean delivery [ 14 ], children undergoing hemodialysis [ 15 ], and critical pediatric patients [ 16 , 17 , 18 ]. Even though some studies highlight EC’s high variability and its lack of agreement with transthoracic echocardiography [ 19 ], transpulmonary thermodilution [ 20 ], and PATD [ 21 ], it has shown promising results for closely tracking trends in COs [ 22 , 23 ]. There are limited studies on veterinary species that demonstrate EC’s utility in anesthetized dogs [ 24 , 25 , 26 , 27 ] and pigs [ 28 ].…”

In animals, invasive pulmonary artery thermodilution (PATD) is a gold standard for cardiac output (CO) monitoring, but it is impractical in clinical settings. This study evaluates the agreement between PATD and noninvasive electrical cardiometry (EC) for measuring CO and analyzes the other EC-derived hemodynamic variables in six healthy anesthetized dogs subjected to four different hemodynamic events in a sequential order: (1) euvolemia (baseline); (2) hemorrhage (33% blood volume loss); (3) autologous blood transfusion; and (4) 20 mL/kg colloid bolus. The CO measurements obtained using PATD and EC are compared using Bland–Altman analysis, Lin’s concordance correlation (LCC), and polar plot analysis. Values of p < 0.05 are considered significant. The EC measurements consistently underpredict the CO values as compared with PATD, and the LCC is 0.65. The EC’s performance is better during hemorrhage, thus indicating its capability in detecting absolute hypovolemia in clinical settings. Even though the percentage error exhibited by EC is 49.4%, which is higher than the standard (<30%), EC displays a good trending ability. Additionally, the EC-derived variables display a significant correlation with the CO measured using PATD. Noninvasive EC may have a potential in monitoring trends in hemodynamics in clinical settings.
