• Failed Allen test indicates inadequate collateral circulation to the hand, making arterial puncture more risky.
• History of peripheral vascular disease indicates compromised blood flow to the limbs, increasing the risk of complications during arterial puncture.
• Presence of a surgical shunt indicates that the desired artery is already compromised and not suitable for puncture. 
• Anticoagulation therapy increases the risk of bleeding complications during arterial puncture, but does not necessarily require an alternative site.
