Multimedia 1: Lung Ultrasound. Lung ultrasound in B-mode shows reverberation artifacts (white horizontal lines) originating from the pleural line (thin tissue that covers the lungs). The pleural line slides back and forth as the patient breathes. This process is known as “lung sliding.”

Multimedia 2: Cardiac Ultrasound. Echocardiogram showing the four chambers of the heart and normal right and left heart function.

Multimedia 3: Vascular Ultrasound. Ultrasound view of the right atrium (top right chamber of the heart) and inferior vena cava (the blood vessel that brings blood from the lower parts of the body back to the heart). There is a venous catheter extending from the inferior vena cava into the right atrium.

Multimedia 4: Pericardial effusion (fluid around the heart): Echocardiographic evidence of fluid around the heart chambers.

Multimedia 5: Pleural effusion (fluid around the lungs): Lung ultrasound evaluation of pleural effusion represented by absent lung artifacts in the area of the pleural fluid with collapsed lung that is displayed as a hyperechoic (white) object moving in the anechoic (black) fluid.
