Sometime in the couple of weeks I saw a study comparing the duration of protection with different masks. There was a table of results comparing surgical masks, N95 (unfitted) , and N95 (fit tested), with durations in the minutes for surgicals, and at least an hour or two for the N95s, regardless of fit testing. I intended to save it for future reference and showing anyone that tries to tell me that surgicals are perfectly fine, but now I can't find it anywhere, and trying a scholar search hasn't turned up the journal article yet either. I assume I saw it in this thread, does anyone know what I'm talking about and happen to have a link handy? The basic information is nice to have, but I'd feel better if I could refer to the genuine article.

I also use a disposable p100 for air travel (only once). put a surgical over it to cover the valve, good to go

Lotta different Aura models. What do the different numbers mean? Here in Euroland there's both a 9320+, 9320D+ and 1862+ available. They look pretty much identical. Edit: See it was addressed, nevermind! And thanks. SplitSoul fucked around with this message at 13:23 on Dec 17, 2021 |

Platystemon posted:Home Depot carries them. There’s a second listing, and they may both be stocked in the same store, one in the paint supplies aisle and the other with hand tools. thank you dude. I ran all over the place yesterday but I guess I'm going into town today for these because we have them everywhere and these are fantastic. I must have like, a gigantic head or something because the plastic straps last me about 10-11 time on and off before the top strap snaps. the braided ones lasted forever.

I’d have to look up the “D”. 9320+ is your basic model. 1862+ is a medical edition that had a fluid‐resistant outer layer and the related regulatory approval. Here’s a full guide. https://multimedia.3m.com/mws/media/842338O/aura-9300-series-respiratory-technical-datasheet.pdf It doesn’t directly answer the “D” question, but from context, it’s made in Germany and perhaps required for some Deutsche reason.

At my company they allow any type of mask to be worn in a crowded office environment including those cloth neck gaiters which were found to be the most ineffective of any mask type.

Our saying “gently caress this” and wearing scary masks and not going to Christmas is, on some level, an attack on that. Me gearing up good and hunkering in the bunker can correctly be interpreted as me saying that I think there’s something wrong with doing less. none of this matters because the gov aint listenin to people who do or do not go to bars, its listening to the bar.

Stereotype posted:I’m probably going to get probated in D&D again for reminding them that there is not any selective pressure making covid less deadly. how could I know?? did I do studies?!?!? That’s one of those “I read something that sounded smart on the internet” type of ideas that people get loving pissed at you for asking them to think about on their own. Is a super fast-acting 100% lethal virus going to run into a wall? Sure, historically, and I bet even today a virus that killed you within an hour would have a hard time going far. That’s got fuckall to do with an asymptomatic spreader that often never gets noticed, especially in a world with airplanes. Saying that a virus always has to turn into the common cold (and do it within two years for some reason) betrays the same level of ignorance as someone saying that evolution doesn’t exist because there are still monkeys that haven’t turned into humans. Different poo poo does different poo poo, and it’s uncommon for a thing to evolve around a problem that it doesn’t have.

lets check in on my patient dying of covid They can't prone him anymore because he's developing subcutaneous emphysema. this xray is positive for pneumomediatsinum and pneumopericardium. it's very difficult to make out though and admittedly im not good at looking at them. but basically for a lot of pressure related reasons air is leaving his lungs and going into his skin. this feels like popcorn if you ever experience it with a patient. Can also lead to a pneumo thorax which might be happening the right lung. that's not as well expanded. for comparison sake, 20 days ago when he was diagnosed with covid.  Also they can't prone him anymore because of the subcutaneous emphysema as well as significant eyelid/scleral edema. Also vascular is now consulted because they can't find pulses in his left leg. He's now on a heparin drip so it's only a matter of time before neuro gets called back in to consult for a brain bleed. This is how you die from covid, btw. just death by a thousand cuts.

Liberals are so stupid believing in things like "natural herd" immunity https://www.sfgate.com/coronavirus/article/omicron-vaccine-protection-hospital-COVID-immune-16703994.php quote:For vaccinated people, case counts aren’t especially meaningful, because they’re largely protected against severe disease. Still, public health officials have argued the mandates are necessary because vaccinated people can both catch and spread COVID-19, especially omicron and delta, two strains which are circulating globally.

Everyone should and will have one of these cool little guys in their house within the next two months and everyone’s lives will be improved by their presence.” Also having bird poo poo on their stuff kills or maims some untold percentage of the population and causes a complete collapse of the healthcare infrastructure, I don’t know, it’s not my simile.

I might check out the masks section in the CSPAM thread but personally feel like vaxxed/n95 is more than enough, especially since we are still limiting our exposure to other people and enclosed spaces as much as is reasonably possible. In case anyone wants elastomerics, this is the full list of NIOSH‐approved non‐valved elastomeric respirators. They approve mask/filter combinations, so there are really only four models: MSA Advantage 290 MSA Advantage 900 GVS Elipse NonValved Dentec 400 NX The first three use the molds of a valved model, so they look like they have valve covers, but there is no valve underneath and exhalation goes through the filters. You may get hassled about them. The Dentec 400 NX is more distinctive, but, well, I’ll let you decide.  Here is the page to search by other criteria. I can find one valveless FFRs (i.e. the disposable mask‐like type) with N100 protection, Shenyang Baianda Safety Co.’s Model EF600.  No one imports and sells it, so far as I can tell.
