Deltex Medical’s esophageal Doppler cardiac output and fluid management system, the CardioQ, is a safe, easy-to-use and minimally invasive alternative to the pulmonary artery catheter (PAC). The CardioQ provides a determination of key cardiac function parameters in real time, based upon measurement of aortic blood flow and without the need for arterial or central venous access. As a flow-based system, the CardioQ is highly sensitive to changes in hemodynamic status and allows for early, rapid and safe intervention.
In contrast to the PAC and devices that rely on pressure to determine cardiac output, the CardioQ allows the clinician to safely, easily and reliably optimize left ventricle preload. The CardioQ has been validated in the surgical and ICU setting in many patient groups. The device can be placed and yield useful information in less than five minutes and has been used in over 300,000 patients without any reported adverse events.
