What percentage of surgical smoke is composed of water vapor?

Surgical smoke is generated during procedures that involve thermal destruction of tissue, such as cauterization or laser surgery. It is important to understand the components of surgical smoke for safety and health considerations. A significant part of surgical smoke is indeed composed of water vapor due to the high temperatures involved in these procedures, which cause moisture in the tissue to evaporate.

Research indicates that approximately 95% of surgical smoke is comprised of water vapor. This high percentage underscores the importance of proper smoke evacuation techniques in operating rooms, not only for maintaining a clear surgical field but also for reducing the risk of inhaling potentially harmful chemical byproducts present in the remaining 5%.

Thus, the assertion that 95% of surgical smoke is composed of water vapor is based on empirical data, supporting the identification of the correct answer within the choices provided. Understanding the makeup of surgical smoke is critical for healthcare professionals to ensure safety protocols are adequately followed.
