The data is available in the supplementary document on CO2 data. Our explanation is that the inspired CO2 rise triggered an increase in minute ventilation and respiratory rate, maintaining EtCO2 within the normal range. In conclusion, after 80 minutes of mask use under resting conditions, there was no significant accumulation of CO2 and no deleterious effects secondary to the observed elevation of inspired CO2. This suggests that any CO2 accumulation under resting conditions will likely be minimal and automatically adjusted by the user through normal physiologic response to CO2 buildup. A similar user test was performed under strenuous physical activity. The results indicate that in exertion simulating that of most healthcare work, the change in inspiratory CO2 throughout use of the device is negligible and in line with NIOSH standards .
