During the application of a TR band, what is the second step?

• A. Flush sheath
• B. Withdraw 2-3 cm of sheath and slide band over puncture site
• C. Align the green marker on the device to the puncture site
• D. Inflate balloon to at least 13 cc or nominal while removing sheath

Answer: (B)

The TR Band must be positioned so the balloon sits directly over the arterial puncture to provide effective compression. The second step involves withdrawing a small amount of the sheath (about 2–3 cm) and sliding the band over the puncture site so the balloon portion will be centered over the arteriotomy. After this, you align the device’s green marker with the puncture site to verify accurate placement, then inflate the balloon to the prescribed volume (often around 13 mL or nominal) while removing the sheath to achieve hemostasis. Flushing the sheath is a preparatory step, but it does not accomplish the positioning required for correct TR Band deployment.
