Air Quality Check in Gastrointestinal Endoscopy Unit

Air pollution sources in indoor area are one of the main factors for reducing indoor air quality of locations. A gastrointestinal endoscopy unit consists of the following area: procedural, recovery areas, and area for a disinfection and cleaning for equipment. This area is frequently exposed to the gastrointestinal gas expelled from patients and gas from electrocoagulated tissue through carbonation or electrocoagulation of neoplasms. This can be potential harmful component for respiratory health not only to medical practitioners but also to the patients who undergo endoscopic examinations. However, there has been scare data for the air quality check in the endoscopic unit.

About this study

Air pollution sources in indoor area are one of the main factors for reducing indoor air quality of locations. A gastrointestinal endoscopy unit consists of the following area: procedural, recovery areas, and area for a disinfection and cleaning for equipment. This area is frequently exposed to the gastrointestinal gas expelled from patients and gas from electrocoagulated tissue through carbonation or electrocoagulation of neoplasms (procedure of endoscopic submucosal dissection, endoscopic mucosal resection, etc). This can be potential harmful component for respiratory health not only to medical practitioners but also to the patients who undergo endoscopic examinations. However, there has been scare data for the air quality check in the endoscopic unit. The aim of this study is to check the air quality using conventional portable passive air quality monitoring sensors in gastrointestinal endoscopy unit.
