Masks

[phrodeau]

Ok, first of all you need to understand the basics here. Droplets are stopped by the mask, or they fall to the floor. They are heavier than air and some are large enough to be caught by a mask like Rob's sneeze.

Aerosolized viruses are not "droplets" and are not heavy enough to simply fall to earth, they are carried on air currents or just linger in the air for quite a long time.

Your idea about the velocity of the aerosolized particle is wrong. A virus is airborne. It doesn't need velocity. It is not being shot at people like some kind of dart. You breathe them in. The amount of air you are breathing out or breathing in as expressed in cubic inches per minute should not vary due to the mask or you are going to get hypoxia. The exchange between air the environment and your lungs also should not significantly change for the same reason.

A too-restrictive mask will cause an increase in carbon dioxide in your bloodstream which is why studies have shown headache for healthcare workers wearing n95s throughout a long shift.

Viruses do not leave infected people except on droplets. First error.

CO2 molecules are much, much, much smaller than viruses. No mask can trap them. Second error.

Ported N95 masks do not restrict exhales, only inhales. Third error.

 

[Lazaran]

You have it exactly right. The layers of cloth do next to nothing to aerosolized droplets. They slow down the air currents that carry them.

Also, I would imagine as the condensation builds up on the material the mask is made from, some of the actual virus is captured by even a less than perfect mask.

The idea that a mask has to be hazmat level to provide any benefit is asinine.

Then again, consider the people who are promoting that narrative.

Queef is still spreading lies about aerosols and cloth masks? I'm shocked.

False.


COVID-19 can kill. Now, according to a misguided Internet-fueled theory, masks can kill, too.

All it takes is a mask-wearer who inhales freshly exhaled carbon dioxide repeatedly until dizzy, unconscious or dead. That, no doubt, would be a shocking development. In the real world, the average mask user without preexisting respiratory illness has nothing to worry about — except COVID-19.

Only an airtight mask could possibly cause any breathing difficulty. That eliminates cloth masks, the preferred personal protective equipment in public. It actually eliminates N95 respirators, too, usually reserved for healthcare professionals. They fit tighter than a cloth mask but still not tight enough on the face to kill. Surgeons wear even more substantial face coverings all day without endangering their health.

But who wouldn’t want a more comfortable N95? John Xu, a research scientist at Stanford University, is developing a modified N95 mask with his colleagues that includes a small box worn at the waist with a tube extending to the mask. The box, through an electrochemical process, produces pure oxygen to compensate for the loss of oxygen caused by the mask. The researchers started their project with the assumption that an N95 mask reduces oxygen intake by anywhere from 5 percent to 20 percent.

An N95 mask could possibly cause:

Hypoxia: When body tissue does not get enough oxygen.

Hypercapnia: Elevated levels of carbon dioxide in the blood that can cause dizziness, shortness of breath, headache and, in extreme cases, hyperventilation, seizures and possible death.

But even an N95 mask is unlikely to produce such extreme reactions. A respiratory illness such as chronic obstructive pulmonary disease, or COPD, can cause both hypoxia and hypercapnia. Those with a preexisting condition who experience breathing difficulties, of course, would almost certainly remove the mask.

A Centers for Disease Control and Prevention representative told Reuters that carbon dioxide, indeed, will collect between the mask and face but not in dangerous amounts and certainly not enough to cause hypercapnia. A mask is designed to trap viral droplets, much larger than tiny carbon dioxide particles. A mask, either N95 or cloth, cannot trap all carbon dioxide particles — they either go through the mask or escape along the mask’s perimeter.

The CDC still recommends cloth masks in public, with these exceptions:

Children under age 2.
Anyone exhibiting breathing difficulties or otherwise incapacitated.

Idiot. Who said, "kill?"

Re-breathing a portion of your exhalations mimics a change in altitude, not putting a bag over your head. You are welcome to try either.

BTW, your "Source" link is not your source. Your source was Snopes. A guy, a coupla laptops, Google, his ex-wife, his girlfriend and a cat or two.

It seems to be getting worse, at one time there was some low level usage of fact in his rationalisations. Since COVID-19 has blown sky high in the US, he has digressed to the cellar of truth and knowledge. Now he seems to be full on fabrication of falsehoods sewn into a narrative fit only for uneducated dolts to believe.

I can sum his issues up in seven letters: ADHD and OCD.

Suddenly he’s concerned about elevated CO2 levels. Makes me wonder if his position on climate change has shifted.

 

[dolf]

Doctors, dentists, decorators, bodyshop sprayers... me. The list of people who wear masks at work, often for hours on end, with no ill effects is a long one.

Prior to this, nobody issued dire warnings that i could keel over dead if i wore a dustmask whilst sanding my kitchen door. Surgeons haven't been fainting at the table. Masks might feel stuffy and claustrophobic, but they don't lower your blood oxygen.

Some people might have a legitimate phobia or ptsd that makes wearing masks unbearable. Someone might have some skin condition or damage to their face, maybe. But short of the rare exceptions, people are just being pussies. Seriously pussyfied. The sort of hysterical babies that make a drama about every minor discomfort and inconvenience in their spoilt pussy lives. They're one breath away from "you're damaging my self esteeeeeem!!!"

The person who says that they won't be using your private business if you impose masks on customers, because they're American and they can wear what they want? Fine!
The pissy bitches who flounce into someone else's business, believing that their feels trump a private businesses right to impose dress codes and safety measures, just to throw giant toddler tantrums, abusing staff for a policy they have no control over? They need time out on the naughty step and no toys or dessert or candy for a month. Well... in all honesty, i think they need a slap. But I don't condone unprovoked violence, even on giant pussies.

 

[Lazaran]

The one and ONLY thing he and others like him care about is the performance of the stock market.

Every single argument they make can be traced directly back to how it's going to affect the markets

You don't have to be trained in contact tracing to figure that out.

Why do you think they're disciples of Trump.

Also, they really don't want people to get a hold of Trump's taxes and financials, because it would expose the big lie that rich people get rich through hard work, and not criminal behavior (Tax avoidance, bank fraud, questionable loans, etc). They're scared shitless that if Trump goes down for some financial crime, the rest of them will be fair game.

The biggest con ever is the rich "conservatives" wrapping themselves in the flag and portraying themselves as super patriots, while shirking their duty to pay taxes that fund the military and public services that they benefit from to a far greater degree than the average citizen.

Fuck all of them.

I thought that's why most of those right wing wimps came to the LitE GB. They secretly like getting their balls and asses kicked and their pussies slapped. They're a very masochistic bunch from what I've deduced.

 

[adrina]

Masks won't protect you - they protect other people if you have the virus. So it's an intelligent, altruistic way of saving the lives of other people.
Oh, sorry - I'm in the GB.... faces are for losers, masks are un-American, I need to shoot people when I have a mask, I know my RIGHTS

If shelf stackers aren't using masks, leave the store

Actually the science is now showing masks provide the wearer with protection as well.

You don't want to be sneezing into your mask, the inside of the mask will feel horrible against your nose and mouth after you've sneezed against it. Its acceptable to pull it down and sneeze into your arm at the elbow, like you perhaps would at any other time.

Horse pucky. I've sneezed inside of mine and it's been fine. In fact that's exactly what they are there for.

And quite frankly, everyone should have a spare by now.

[Celand]

A perfect argument

 

[SpeareChucker]

People just don't get it. Went to the grocery store yesterday. There was a stocker putting out the bigger cans of sodas. He had to sneeze. He pulls his mask down, sneezes into his hands, puts the mask back up and continues to stock cans.

Masks cost money.
Maybe he had no backup
and didn't want to spend the rest of the day with a mess on his face.

As someone with bodyshop and paint experience,
you don't wear the mask all that long.

If you're in the booth for more than half-an-hour
you're seriously doing something wrong...

 

[Conager]

A prefect argument

It would be if, say, viruses were the size of bees, and the weave of masks was smaller than bees.

It would be more analogous is masks provided actual protection, instead of looking protective.

Far as I know, be keeping gear is 100 percent effective at stopping bees.

I'm pretty sure you managed to last your half hour without throwing a tantrum, crying, assaulting anyone, trashing the shop and claiming you're on the brink of passing out. On account of not being a fucking pussy.

 

[SpeareChucker]

My employer didn't give a shit if I wore a mask or not.

Can you not see the difference or

are you a sheeple?

 

[SpeareChucker]

Similarly, I was not bound to my job by law/mandate...

It was a choice. See???

I like this experiment. You could reproduce it in any middle school science lab.

Even if some of the virus gets through, it's possible that numbers matter, and reducing the amount hitting you might reduce the degree of the illness. This is true of some germs, but not all, do until the research is in it's good to play it safe.

What year was this?! Serious question, because these days most places will fire a person who refuses to follow health and safety.

Like how seatbelts and helmets used to be optional, but now you're looking at a ticket.
