A recent and prior two studies that show facial COVID masks (surgical) are very toxic and dangerous and I warn parents again, these masks do NOT work, ineffective, and are very dangerous to your child

Inhaled CO2 concentration while wearing face masks: a pilot study using capnography (Martellucci et al.); Preliminary report on surgical mask induced deoxygenation during major surgery (Beder et al.)
SOURCE:
“The mean CO2 concentration was 4965±1047 ppm with surgical masks, and 9396±2254 ppm with FFP2 respirators. The proportion of the sample showing a CO2 concentration higher than the 5000 ppm acceptable exposure threshold recommended for workers was 40.2% while wearing surgical masks, 99.0% while wearing FFP2 respirators. The mean blood oxygen saturation remained >96%, and the mean end-tidal CO2 <33 mmHg. Adjusting for age, gender, BMI, and smoking, the inhaled air CO2 concentration significantly increased with increasing respiratory rate (with a mean of 10,143±2782 ppm among the participants taking 18 or more breaths per minute, while wearing FFP2 respirators), and was higher among the minors, who showed a mean CO2 concentration of 12,847±2898 ppm, while wearing FFP2 respirators. If these results will be confirmed, the current guidelines on mask-wearing could be updated to integrate recommendations for slow breathing and a more targeted use when contagion risk is low.”
