Inadequate visibility during laparoscopic electrosurgery could significantly impact surgical outcomes.

• Light obscuration reached 47% after 60 seconds of electrosurgery.
• Introducing CO2 at 5, 10, and 15 L/min significantly reduced obscuration to 13%, 5%, and 2%, respectively, 60 seconds post-electrosurgery.

Using higher CO2 flow rates can enhance visibility during procedures, potentially improving patient safety and outcomes.

• Computational models accurately predict how flow rates affect obscuration dynamics.
