Hand-carried cardiac ultrasound (HCU) device: Recommendations regarding new technology. A report from the echocardiography task force on new technology of the nomenclature and standards committee of the American Society of Echocardiography

The newest introduction to echocardiography is a hand-carried ultrasound (HCU) device. It is a small echocardiographic machine that typically weighs less than 6 lb and can obtain echocardiographic images and data. However, neither the device nor the context of the examination fulfills the criteria for a comprehensive or complete echocardiographic examination. The American Society of Echocardiography believes that HCU will extend the concept of the "complete physical examination," allowing more rapid assessment of cardiovascular anatomy, function, and physiology. However, appropriate user-specific training (Level 1 at a minimum) and assumption of responsibility are essential to ensure the most accurate acquisition, interpretation, and use of the data.
