ULTRASOUND AS A METHOD TO DETECT BUBBLES OR PARTICULATE MATTER IN THE ARTERIAL LINE DURING CARDIOPULMONARY BYPASS.

Summary Ultrasound techniques make it possible to accurately detect bubbles or particulate matter in a fluid medium. These techniques have been employed in the present studies to determine the presence and size of bubbles in the arterial line of the extracorporeal circuit. Ultrasound has no apparent ill effect on the blood and is a very accurate method of detecting bubbles of almost any size.
