A Study was conducted to assess whether the use of an N95 mask by children was associated with episodes of desaturation or respiratory distress.

22 healthy children were randomly allocated to one of two groups: one without an exhalation valve and the other with an exhalation valve, all wearing a N95 mask. Over the course of 72 minutes of mask use, researchers monitored changes in partial pressure of end-tidal carbon dioxide (PETCO2), oxygen saturation, pulse rate, and respiratory rate. Every 15 minutes, both participants were tracked for the first 30 minutes while not wearing a mask and the next 30 minutes while wearing one. After that, the kids did a 12-minute walking exercise.

Results:
--Children did not experience a statistically significant change in oxygen saturation or pulse rate during the study.

--There was a significant increase in respiratory rate and PETCO2 in those children wearing a mask without an exhalation valve, whereas this was only seen in those children wearing a mask with an exhalation valve after the walking test.

The use of a N95 mask, in particular, could cause breathing difficulties in children if the mask does not have an exhalation valve, particularly during physical activity. It was thought that using a surgical mask would be more suitable for infants.
