What is a TR band used for?

• A. Hemostasis at the femoral artery
• B. Manual compression for radial sheath pull
• C. Occlusion testing of the radial artery
• D. Vein compression for access site

Answer: (B)

The main idea is that this device provides controlled, targeted pressure to the radial puncture site to achieve hemostasis after transradial access. It sits around the wrist with a small balloon that you inflate to apply gentle pressure, essentially taking the place of manual compression once you pull the sheath. This helps stop bleeding while preserving arterial flow, and you gradually deflate according to protocol to avoid rebleeding or radial artery occlusion.

It isn’t for stopping bleeding from the femoral artery, it’s not used for testing radial artery occlusion, and it isn’t about vein compression. The purpose is specifically to secure hemostasis at the radial access site after the sheath is removed via a controlled, device-assisted form of compression.
