In this episode you will learn: - The Allen test assesses collateral circulation via the ulnar artery before a radial artery puncture. - A positive result, where the palm pinks up in 5-15 seconds after releasing ulnar pressure, indicates it is safe to proceed. - A negative result, where the hand remains pale, is a contraindication for using the radial artery on that arm. - Exam questions often test the correct interpretation of positive vs. negative results and the appropriate next action. - The term "Modified Allen Test" is the standard procedure tested on the exam, involving the release of the ulnar artery first.
