Recovery Room Ventilation
I
f you are reading this month's ASHRAE Journal, there is
a good chance you or someone you know h a s been under
anesthesia.
When you wake up, you aren't thinking about the
ventilation, airfl ow pattern or temperature distribution in
the recovery room, but the health-care workers are. As the
author of our cover article, Kishor Khankari, Ph.D., Fellow ASHRAE, notes,
the airfl ow patterns in the post-anesthesia care unit (PACU) play a crucial
role in determining the spread and concentration of waste anesthetic gases
(WAGs) in the breathing zone of occupants.
Read about this on page 2 2. You can also hear Khankari, a regular
Drew Champlin
contributor to ASHRAE Journal, on our Hot Air podcast with Technical
Editor Rebecca Matyasovski. He provides some added explanation for his
article on optimization of ventilation design for the hospital post-anesthesia
care unit. Search for Hot Air on any podcast platform or visit here: https://

Our featured ASHRAE Journal Podcast episode is a conversation with
Kelley Cramm, P.E., Life Member ASHRAE, on her May 2022 Engineer's
Notebook article, co-authored with Brad Chambon, on Elevator HVAC
Design Requirements. Th e podcast updates information from the article.
" Th e article covered hoistway venting in detail, and I noted in the article,
hoistway venting was required by the International Building Code prior to
2015, " Cramm said. " Th e 2015 International Building Code eliminated the
requirement for hoistway venting. But when I wrote the article, I did some
research, and there were many code jurisdictions that were still under the
2012 IBC. So hoistway venting was required in those jurisdictions and it
seemed relevant.
" Since then, I did another round of research, and many jurisdictions
have updated their adopted codes to the 2015 or later versions, so that
means that hoistway venting is no longer relevant. However, designers
really do still need to do research for their projec t to determine what the
local authority requires. "
