1. A radial compression band configured to provide hemostatic compression to an arterial access site on the arm of a wearer after an arterial sheath is removed from the access site, said radial compression band comprising:
- an elongated arm band presenting an inner surface, an outer surface, and an arm opening defined at least partly by the inner surface and sized to receive the arm,said arm band presenting proximal and distal margins, with the arm opening being defined between the margins;
an arterial pressure surface facing radially inward relative to the arm band for compressive engagement with the access site; and
a Doppler probe coupled to the arm band and spaced from the pressure surface to sense blood flow through the artery and thereby facilitate arterial patency during hemostasis of the access site, with spacing between the pressure surface and Doppler probe providing an open area configured to overlie the access site,said arm band presenting an access opening located between the pressure surface and the Doppler probe,said access opening extending continuously through the arm band from the outer surface to intersect the inner surface at a location aligned with the open area between the pressure surface and the Doppler probe, with the access opening being configured to receive the arterial sheath and permit the arterial sheath to pass directly through the arm band to the access site when the radial compression band is donned.

Abstract
A radial compression band is configured to provide hemostatic compression to an arterial access site on the arm of a wearer. The radial compression band includes an elongated arm band that presents an arm opening sized to receive the arm. The arm band presents proximal and distal margins, with the arm opening being defined between the margins.
