Q

THORACIC OUTLET SYNDROME (TOS)
What is the Adson
maneuver?
P622

A
Evaluates for arterial compromise
Patient:
    1. Extends neck (lifts head)
    2. Takes a deep breath and holds
    3. Turns head toward examined side
Physician:
    Monitors radial pulse on examined side
    Test finding is positive if the radial
       pulse decreases or disappears
       during maneuver
