From January 2009 to June 2011, we randomized 2107 TRA to low (13cc of air) versus ultra low (10 cc) inflation volume in the TR Band™ compression device. If bleeding occurred, 2 cc were added. After device positioning, type of compression was assessed (“patent hemostasis” or not). Compression was maintained for at least 4 hours. Radial artery patency was evaluated at 24 h by pulse oximetry during ulnar compression. Factors related to patency defined as positive pulse oximetry (PPO) were analyzed.
