Face masks don't restrict oxygen or contribute to carbon dioxide buildup: study

Breathe easy. A new study suggests that surgical face masks don’t cause a buildup of carbon dioxide or restrict oxygen, despite opposing claims. The study, on the “Effect of Face Masks on Gas Exchange in Healthy Persons and Patients with COPD,” which was published in the Annals of the American Thoracic Society on Friday, was conducted after a group of Florida residents challenged Florida’s mask-wearing mandate in June, arguing that wearing the protective face coverings could result in the buildup of too much carbon dioxide.

Medical workers don’t wear them all day, everywhere - just in certain patient contact situations. And it’s for keeping out bacteria, not viruses.

The company that makes these face diapers must be the one who paid fr this so called study. You get what you pay for I’ve always heard.

The P100 (pink) filters in my industrial face mask recommend a six to ten minute use cycle. That’s with an exhaust valve.

They don’t wear masks all day long. They wear them for a few hours (in a cold, high oxygen environment, if they’re in the OR) and not every day, but only in surgery or if making the rounds where bacterial contamination might be a problem.

If your SpO2 dropped to the level of brain dysfunction and muscular paralysis simply because you put a piece of cloth across your face, you should never have been in the medical field to begin with because there’s something severely wrong with your pulmonary system.

You should seek medical assistance to help identify and correct whatever abnormality is causing this problem for you. In an N95 mask and walking on a treadmill for an hour at 2.5mph, normal test subjects see a ~0.4% decrease in SpO2. http://www.rcjournal.com/contents/05.10/05.10.0569.pdf

You mean like walking on a treadmill for an hour with an N95 mask on at 2.5mph?

0.4% drop in SpO2.

“new study suggests that surgical face masks don’t cause a buildup of carbon dioxide or restrict oxygen,”

“Suggest” is the key word here.

AS always one study does not means very much. Most of these studies done in the time of COVID lack scientific rigor. The study above, from 2008, is a better designed attempt to answer that question.
Excerpt
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.

Nice review of many studies

-—A new study suggests that surgical face masks don’t cause a buildup of carbon dioxide or restrict oxygen, despite opposing claims-—

I did my own study and it suggests that surgical face masks DO restrict oxygen despite the above study.

Except covid is 3 microns and only n95, n99s stop that - all others are a political/social statement

Only a Democrat President can stop this virus. Biden will reach out to the Virus..he will sit down with the virus and have a serious but pleasant conversation with the virus. And resolve our differences.

From the paper:
“Dyspnea, the feeling of shortness of breath, felt with masks by some is not synonymous of alterations in gas exchange. It likely occurs from restriction of air flow with the mask in particular when higher ventilation is needed (on exertion).”

OK, but O2 flow is good. Got it.

“Surgical face masks” I love how the title reads “Face masks” but then you read that the study was concerning “surgical face masks”. I don’t believe people claim that those type of masks were a problem regarding O2 restriction or CO2 buildup. The concern has been with homemade face coverings of sufficient thickness to restrict exposure to or spreading of the virus

You have no idea what you are talking about. This percentage happens with everyone wearing a mask.

Happens with all the nurses, we all measured it.

No brain dysfunction happens at 86%, another example of you being stupiid and lying about all this.

I have one of those finger 02 testers and the number drops from97/98 to 89/91 while wearing a blue med mask.

Then why does almost everyone I know choke and cough when they take them off after wearing them for an hour or more?
