title: Ultrasound cardiac output units.
abstract: We evaluated 2 dedicated CO US units that calculate CO for teenage and adult ranges. We also tested a unit designed for use on neonatal to pediatric patients and discussed this device separately. Because of the limitations of US technology, we found these units to be best suited for trending CO; however, the utility of US CO for this application far outweighs its limitations.
