Objectives
Many individuals have difficulty adapting to face mask use and report symptoms while using masks. Our primary objective was to determine whether continuous mask-wearing causes elevated levels of carbon dioxide (CO2) behind the facemasks.
Methods

These CO2 concentrations were also measured in several randomly selected subjects after a 5-minute walk.
Results
There were significantly higher CO2 concentrations behind the mask …
