Introduction:
To characterize the smoke generated during several endoscopic procedures and evaluate the efficacy of a smoke evacuation system as a preventative measure.
Methods:
Monitoring devices in closure proximity to patients measured particulate matter and volatile organic compounds during endoscopic procedures. The impact of a smoke evacuator system was also assessed.
Results:
Particulate matter and volatile organic compound levels were significantly elevated during all procedures. The smoke evacuator reduced the exposure.
Discussion:
Smoke produced during endoscopy is a potential health risk for endoscopy staff. Protective measures and further research on long-term exposure effects are warranted.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
