Intrapulmonary shunting definition
WebPulmonary shunting is that portion of the cardiac output. that moves from the right side to the left side of the heart without being exposed to alveolar oxygen (PAo2) Absolute shunts are called True shunts and can be grouped under the following two categories. Anatomic shunts and capillary shunts. WebIntrapulmonary arteriovenous shunting was suspected. Transthoracic echocardiography with agitated saline contrast injection from the right antecubital vein was performed. Late arrival of saline contrast bubbles in the left atrium by pulmonary veins leading to complete left heart opacification confirmed the diagnosis of significant intrapulmonary shunting.
