allens test

[@smoleton]

Great video... for this talking about the thumb on the radial artery, this Allen's test is done prior before a radial artery puncture for ABGs to determine the presence of collateral circulation. If pinkness fails to return within 6-7 seconds, the ulnar artery is insufficient, indicating that the radial artery should not be used for obtaining blood specimen
