What happens when a Balloon is inflated at low pressure?

When a balloon is inflated at low pressure, it primarily functions to redirect blood flow rather than causing significant changes to the vessel structure or contributing to thrombus formation. Inflating a balloon at a lower pressure allows for gentle expansion of the vessel walls, which can temporarily alter the flow dynamics within a vascular structure. This is often utilized in procedures like balloon angioplasty, where the goal is to enhance blood flow without causing trauma or damage to the endothelium of the blood vessel.

This method minimizes the risk of vessel wall destruction or significant injury, as a low-pressure inflation is less likely to cause tearing or other forms of trauma compared to higher-pressure inflation. Additionally, a lower pressure does not typically lead to an increased risk of thrombosis, as excessive injury to the vessel wall can trigger a healing response that promotes clot formation. Also, it does not actively contribute to decreasing plaque buildup; rather, the process is focused on improving blood flow or reducing the obstruction temporarily. Thus, the outcome of redirecting flow is the most relevant consequence of inflating a balloon at low pressure.
