Use of carbon dioxide measurements to assess ventilation in an acute care hospital

Poorly ventilated indoor spaces pose a risk for airborne transmission of SARS-CoV-2. We measured carbon dioxide levels in a multiple areas in an acute care hospital to assess the adequacy of ventilation. Carbon dioxide levels remained below 800 parts per million in most areas but exceeded this level in a small conference room with 8 occupants, an office with 3 occupants, and a bathroom with 2 occupants. Measuring carbon dioxide levels could provide a simple means for healthcare facilities to assess the adequacy of ventilation.

Automated summary

Poorly ventilated indoor spaces can increase the risk of airborne transmission of SARS-CoV-2. We measured carbon dioxide levels in multiple areas of an acute care hospital and found that some areas exceeded 800 ppm. Measuring carbon dioxide levels could provide a simple way for healthcare facilities to assess ventilation.
