ECOM® (Endotracheal Cardiac Output Monitoring) is for use on intubated patients, and allows the clinician to manage the patient using information derived from a core monitoring location in close proximity to the ascending aorta. ECOM® is straightforward to operate and gives real-time information for patient hemodynamic optimization. The system is automatic and self-adjusting for positional changes allowing the clinician to focus on the patient instead of the device. ECOM® provides the cardiac output, stroke volume variation and systemic vascular resistance to be used as part of Goal Directed Therapy protocols.
