Abstract: A system and a method of non-invasive continuous echocardiographic monitoring is provided with an ultrasound transducer and a bedside monitor. The beside monitor includes a monitor central processing unit (CPU). First, the ultrasound transducer is attached onto a specific skin portion of a patient. The specific skin portion is positioned adjacent to a patient's heart. Next, continuous echocardiographic data is sensed with the ultrasound transducer.

Finally, the real-time ultrasound image is outputted with the bedside monitor. If the bedside monitor has a main screen, then the real-time ultrasound image is displayed through a picture-in-picture format with the main screen.
