Which factor is most directly implicated in determining the length of manual pressure after sheath removal?

• A. Sheath size
• B. Patient coagulation factors
• C. Medications being administered
• D. Institution policy

Answer: (A)

The key concept is that the size of the arterial puncture created by the sheath directly dictates how long you need to apply manual pressure to achieve hemostasis. A larger sheath leaves a bigger hole, so more tissue must be compressed and clot formation must seal a larger opening, requiring longer compression. While factors like coagulation status or medications can influence how quickly bleeding stops, they don’t determine the mechanical duration needed as directly as the puncture size. Institutional policy doesn’t set the physiological measure of compression time.
