Assembly Bill 563 mandates that hospitals and ambulatory surgical centers in Wisconsin implement policies to prevent exposure to surgical smoke in operating rooms. The bill requires the use of a smoke evacuation system during any surgical procedure likely to generate surgical smoke, which is defined as the gaseous byproduct from energy-generating devices. However, it allows for exceptions if the healthcare provider determines that using such a system is not necessary or advisable for the specific procedure.

The bill also includes definitions for key terms such as "operating room," "smoke evacuation system," and "surgical smoke." The Department of Health Services is tasked with enforcing these requirements, ensuring that healthcare facilities take appropriate measures to protect both patients and staff from the harmful effects of surgical smoke.
