[Bldg-sim] Acceptable CO2 levels

[Zoon, W.A.C.]

Dear Amit,

Next to the things already mentioned, hospital ventilation systems should have additional properties. For some rooms additional measures need to be taken. The operating theatres and the rooms around it need special care regarding surgical site infections. They basically are laboratory environments. If you do not have any experience in this area, consult with someone who has.

The relatively high ventilation rates in the patient wards can lead to draught problems that need to be taken into account. Patient wards with a lot of equipment (for example haemodialysis wards) might need extra cooling and thus possibly a higher ventilation rate.

Another thing to take into acount is the risk of cross-infection, both between wards and within a single ward with multiple patients. Some research on this topic has been done in Sheffield and in Copenhagen.

Kind regards,
Wiebe Zoon.

Amit,

I don't have the fundamentals here, but I recall a dinstinction is made for recommended ventilation rates based on the type of room considered: operating, recovery, ... Furthermore, I know specific requirements exist depending on the risk of infection for or from the patient.

So, I think you cannot simply state it as such. Maybe contact the research group of Jan Hensen (Technical University Eindhoven), I know they have worked on conditioning of operating rooms.

Good luck,

Leen Peeters

Hi all,
This question is not directly related to the group but i wanted to  throw it in as many of you might know the answer.

What is the acceptable CO2 level for a healthcare facility? Can i find the number in any ASHRAE standards?
