What type of pressure should be held on arterial sites once hemostasis is obtained after initial efforts?

Holding light pressure on arterial sites after achieving hemostasis is essential for several reasons. After the initial hemostatic attempts, the goal is to maintain a balance where blood flow is sufficiently controlled without compromising circulation or causing additional trauma. Light pressure allows for the continued assessment of bleeding while providing just enough compression to keep the blood vessel closed.

Excessive pressure can damage the vessel or surrounding tissues, possibly leading to complications like hematoma formation or even compromising the flow of blood to the affected area. Conversely, applying no pressure can increase the risk of bleeding from the puncture site, potentially leading to severe hemorrhage. Variable pressure does not provide the stability needed for optimal healing at the puncture site, risking either insufficient hemostasis or undue pressure on the surrounding anatomy.

By using light pressure after initial hemostatic measures, healthcare providers can ensure adequate closure of the puncture site, all while monitoring for any signs of bleeding or complications, thereby promoting effective recovery and minimizing risk.
