Evaluative Tests Using The Suprasternal Notch
Intrathoracic pressure is measured by using a transducer held in such a way over the body that an actuator engages the soft tissue that is located above the suprasternal notch.
- Dissecting aneurysm
To carry out this test it is necessary to place an index finger or middle finger on the notch and palpate it. In a young normal person there should be no palpable pulse. A prominent pulse may be indicative of an uncoiled aorta, arch aneurysm, or a tortuous blood vessel. The most likely cause of a suprasternal pulse in an adult is an aortic arch aneurysm, while the most likely cause in a child is coarctation of the aorta.

Famous quotes containing the words notch and/or tests:

“Although she feeds me bread of bitterness,
And sinks into my throat her tigers tooth,
Stealing my breath of life, I will confess
I love this cultured hell that tests my youth!”
