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.)
1)Inhaled CO2 concentration while wearing face masks: a pilot study using capnography
“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.”
2)Preliminary report on surgical mask induced deoxygenation during major surgery
“Objectives: This study was undertaken to evaluate whether the surgeons' oxygen saturation of hemoglobin was affected by the surgical mask or not during major operations.
Methods: Repeated measures, longitudinal and prospective observational study was performed on 53 surgeons using a pulse oximeter pre and postoperatively.
Results: Our study revealed a decrease in the oxygen saturation of arterial pulsations (SpO2) and a slight increase in pulse rates compared to preoperative values in all surgeon groups. The decrease was more prominent in the surgeons aged over 35.
Conclusions: Considering our findings, pulse rates of the surgeon's increase and SpO2 decrease after the first hour. This early change in SpO2 may be either due to the facial mask or the operational stress. Since a very small decrease in saturation at this level, reflects a large decrease in PaO2, our findings may have a clinical value for the health workers and the surgeons.”
We showed this back in 2020:
Hypercapnia is one of the most dangerous aspects of mask-wearing.
That five-part series of studies is still the most comprehensive that I have seen on masks lack of safety, lack of effectiveness.
Gee. Isn't that the whole f-kng point of the con game called Covid-19? Nothing is supposed to help. And you must die a very unhappy death. The worst part must be for all the concentration camp doctors deep in denial in the Heimat. Of course needle and damage done. Further the human face by being eradicated abolishes the face of God.
