Q: Are Bronchoscopy procedures to be performed in negative pressure rooms under all circumstances, or can they be performed in OR suites? Does the negative pressure rule only apply to new construction, or does it apply universally to all facilities old and new?
A: According to the 2010 FGI Guidelines for Design and Construction of Health Care Facilities, ventilation requirements for a Bronchoscopy procedure room requires negative air pressure relationship to the surrounding area, and a minimum of 2 outdoor air exchanges per hour and a total of 12 air exchanges per hour. This ventilation requirement must be met regardless where the Bronchoscopy procedure is conducted, which includes the operating rooms. So, to answer your first question: Yes, this requirement applies to all circumstances.
The ventilation requirements found in the 2010 FGI guidelines applies to new construction or renovated areas. It is not a standard, and it does not apply to existing conditions. However, the ventilation requirements for Bronchoscopy procedures have been consistent since the 1996-1997 edition of the guidelines, and perhaps even before that (I only have records back to the 1996-1997 edition). So, if you have constructed or renovated the Bronchoscopy procedure room since 1996-1997, then these ventilation requirements must be complied with.
Some authorities will allow deviance from the FGI guidelines as they are guidelines and not standards. So, if you have extenuating circumstances that requires you to deviate from the FGI guidelines, then contact your AHJ to determine what their expectations are.
