The Accuracy and Precision of the CONMED ECMTM in the Porcine Model (sus scrofa - Yorkshire cross)
Abstract
Background: The use of invasive monitoring is complicated by several factors. It is imperative for those wounded in battle that we explore potential technologies that can aid in the management of effective fluid resuscitation. Objectives: To explore the accuracy and precision of a FDA approved device, the CONMED by comparing it to the Edwards Vigilance II monitor pulmonary artery catheter under hypothermic and hemorrhagic conditions. Methods: 8 anesthetized, instrumented and stabilized in exp. 1 (hemorrhage), induced Type III hemorrhagic conditions. CO values were collected from the PAC and the ECOM over a 3 hour period. Exp. 2 (hypothermia), swine were cooled to a temperature of 33oC and CO values recorded from both instruments. Results: The curves from the ECOM data were significantly different from the PAC data curves under both conditions, but more pronounced differences were found under hemorrhagic conditions. Conclusion: The ECOM does not appear to reliably reproduce CO values acquired from a traditional PAC under hemorrhagic conditions.
