Manual compression

For femoral arterial access, manual pressure is held just proximal to the skin entry point (over the actual arteriotomy, which is typically slightly proximal to the skin nick) for a duration based on sheath size and anticoagulation status — commonly 10–20 minutes minimum, longer if anticoagulated, with gradual release to check for rebleeding before fully releasing pressure. For radial access, a compression device (e.g., a band) is applied with patent hemostasis technique — maintaining radial artery patency (confirmed by pulse oximetry/plethysmography on the thumb) while still controlling bleeding at the puncture site.
