What is the maximum acceptable pressure for small vessels during injection?

The maximum acceptable pressure for small vessels during injection is 450 psi or less. This threshold is important to ensure the safety of the vascular structures being treated. Small vessels, such as those in the peripheral or vascular regions, have thinner walls and are more susceptible to damage from excessive pressure. Maintaining a limit of 450 psi minimizes the risk of complications such as vessel rupture, hematoma formation, or extravasation, which can lead to significant tissue damage and complications for the patient.

In clinical practice, adhering to this safety limit is crucial, especially when administering contrast agents or therapeutic substances during interventional procedures. Technologies and devices used for injections are often calibrated to operate within these pressure parameters, ensuring that they can effectively deliver materials without compromising vessel integrity. By setting this threshold, clinicians can optimize patient safety while achieving the desired clinical outcomes.
