In terms of energy delivery, how do fluids and air differ in effectiveness during ablation?

The effectiveness of energy delivery during ablation is significantly influenced by the medium through which the energy is transmitted. Fluids, such as saline or other conductive liquids, are particularly effective in transmitting energy compared to air. This is because fluids have a higher thermal conductivity and can better facilitate the transfer of energy through direct contact with the tissue being treated.

In contrast, air is less effective at conducting energy due to its lower thermal conductivity and density. This means that when energy, such as radiofrequency or laser, is delivered through air, more energy is lost to the surrounding environment rather than being transferred effectively to the target tissue. Therefore, using fluids for energy delivery during ablation ensures a more efficient and effective transfer of energy, leading to better outcomes in the procedure.

This understanding is critical in selecting appropriate energy delivery methods during ablation procedures, as it highlights the superior role that fluids play in maximizing energy efficiency and effectiveness.
