Not even remotely overkill. This is my PPE set up as well (except for the blue tooth headset). The CDC get up just isn’t enough if you’re going to intubate a covid+ patient. Be safe.

John Yarzagaray The CDC published a webinar two days ago on the use of reusable elastomeric respirators like this one. Many are leaning towards it in several large hospitals in the USA. kzfaq.info/get/bejne/bt2UaKWpl8y6dH0.html

Alex Chamessian The AfterShokz headset had a microphone which uses bone conduction as well as air conduction. We communicate via voice channel on Discord.

@@staffnsnake Any suggestion of what to use when speaking to awake Covid 19 patients-having to shout but the elderly are having difficulty hearing me.

@@staffnsnake Hi! We're looking into this solution too! Any tips on how to keep the headset clean? Is it just Cavi-wipes? A more involved solution by MDRD?

@@staffnsnake is that an app.. Discord?

I did one on this same channel.

You know what? We have shortages too. But we are not pointing the finger at our hospitals for being blindsided by this. We all were. Nobody expected them to keep dozens of PAPR kits in a stockpile. The level of theft in many hospitals was also underestimated. So no-one is blaming them. Instead, many of us have taken matters into our own hands for our own sakes and that of the nurses working closely with us. Relations remain cordial with various hospital admins as we all work together to get through this difficult time.

That’s why I bought my own PPE (3M 6800 Full face mask respirator and hooded tyvek suits). The stuff the hospital gave us is inadequate IMO but, in fairness, aligns with what the CDC recommends.

Same way I can buy my own respirator, the hospital can buy it for their staff too. But they don't. Because they want to protect their own bottom line. The ceo wants to keep his profits and million dollar salary. Doctors are seen as disposable here in the USA. A fire fighter fights a fire with proper training, with equipment and is not thrown into it naked. I didn't work hard for 15yrs to be threaten from the hospital to be thrown out of my fellowship program because I want proper PPE or not want to die. Our hospital all they've done is just lie and lie. We get donations sent of n95 masks and they don't deliver it to our department. It gets seized.. Also, a soldier gets better compensation when in war then us. We get paid shit for this

This basically what i'm doing. Wipe down the outside of the mask, filters (i use 6035 P3R's) and straps as the last step inside the hotzone, when i get out to the mask doffing station it comes off like in the video and then gets a second all over clean then into a plastic bag and into my PPE kit bag

I would be cautious doing that as it adds another step that can lead to contamination. Some of us have considered a 70% alcohol spray before doffing but again it is just another thing to go wrong. With your hands on the straps only and doffing as shown, it is no more risky than doffing a disposable N95. When cleaning the respirator you should wear gloves and a face shield.

While 70% isopropyl or 80% ethanol alcohol work for decontamination, 3M warns it will degrade your masks faster, only use it if no other option is available (your life is more important then the masks), otherwise 3M recommends cleaning with a certain concentration of diluted sodium hypoclorite, that is After you cleaned the mask with water that does not exceed 49°C or 120°F and detergent/soap without oils, lanolin or solvents. If the mask is degraded too far, you might not be able to get or keep the negative/positive air seal or the inhalation valve may be damaged. If you have cardridge with plastic housings, you can of course clean the plastic housing without a problem, just the inner filter should be avoided, as you would damage it. Note the decontamination wipes 3M sells that are supposedly safe to use on your masks, are probably a very low concentration of isopropyl (5-15%), which is not enough to deactivate SARS-CoV-2, always look at chemicals used in wipes and their concentration... Or simply just buy a bottle of the alcohol itself and some clean paper wipes and be done, but remember the thing were masks degrade faster. Here is a PDF from 3M which they actively update: multimedia.3m.com/mws/media/1793959O/cleaning-and-disinfecting-3m-reusable-respirators-following-potential-exposure-to-coronaviruses.pdf

Our protocol is to doff all but the respirator in the red zone, then move to a green zone to doff the respirator and clean it. This zone for us is the theatre dirty utility room. As far as the coveralls are concerned, yes we only use them once. The subject in the video chose a size too small and had difficulty doffing. Nevertheless, even with the correct size, you must be very careful while doffing them, lest you infect yourself.

Thank you!

Im a Hemodialysis Nurse who stays and dialyzed a pt anywhere from 4-10hrs continously. I do have the 3M 6800 also provides by myself. So much confident using the respirator over the N95. Feels like I am able to give my all when using the respirator. Anyhow, right after taking off the Respirator immediately put it inside a plastic bag then close it immediately. Once I have all changed up wearing my goggles and surgical mask plus a new gown and still double gloved. I would disconnect the P100 filter while inside the plastic bag holding the respirator from outside the plastic bag. Then I would leave the P100 in the plastic bag. The respirator will be given a wipe off with disinfectant wipes. Once I get back to the utility area I would put the respirator on my own plastic bin then soak em with 1:100 bleach until I am off my shift. Then rinsed twice before going home. Once I got home I would soak with soapy warm water. Then scrub with soft sponge all the way to me taking shower right after cleanup of my BFF Respirator. Yes I call my 6800 as BFF, its a life saver. Hope this helps and stay safe.

@@hanselsanjuan7522 kzfaq.info/get/bejne/bt2UaKWpl8y6dH0.html This CDC presentation summarise the latest research. I will just add that your sebum or organic material (droplets, blood, etc ...) will reduce the bleach effectiveness. Bleach is a disinfectant, not a cleaner. It is more advisable to clean with soap and water, then disinfect with bleach 2 minutes 1:100 or 50 or 10. Respirators should be doffed last. The respirator and filter casing (not the filtering media or flat disc-type filters) can be wiped with ethanol or disinfectant wipes between patients.

Just pretend the two filters are ears and loop the surgical mask over each filter, that should cover the inhalation valve area. If it does not cover it adequetly, tape the surgical mask in place over the outlet area. Pre-cut the tape or use a thinner tape than the standard width, fold a peel tab onto the tape like you do for wrists for easy removal. Note: dont let the surgical mask come in contact with the flapper, the respirator should have a removable shield in place like the 6800 series has, making it impossible for the surgical mask to droop into the exhalation flap and accidentally not allow it to close.

Not enough room

You buy a glass adaptor from 3M and ask your optometrist to make a prescription lenses for this particular frame

I used P100

midaztouch I use 6035 or 6038.

7093 in the US

7093

You don’t, unless you can source some kind of sports strap that facilitates a seal around the side of the face. More generally, people who must wear glasses should use a 7500 series half-face respirator.

Shika Hookah I'm not him but check the detailed pics on the 3M website, they also cover filters and correct markings. As for lasting, if you have a P3 R rated set of filters or better, they will last more than 12hrs in a relatively clean environment like an airplane, the filters in particular the R rated ones would last more than one 12hrs use easily unless for some reason you are in a very dirty/dusty environment. When they stop working you'll notice by it being harder to breathe in, they don't stop protecting you they just start having more pressure needed for the air to go through.

Use a 3M 6035 or 6038. In North America the 6038 is the 7093.

@@staffnsnake cheers mate!

David Guerrero I cannot say what is best other than to reiterate 3M’s standard for their particulate filters. The 6035 and 6038 filter up to P3 standard (I think that is N99) when used with a full face respirator and P2/N95 with a half face respirator. Those cartridges are good for “the duration of one pandemic wave”. How that is defined is not specified in 3M’s literature but seems to be some months.

@@staffnsnake I have one and use it at hospital.in emergency room ..

Particulate filters don't allow penetration much of particulates (which viruses are). It will just be harder and harder to breath through. Swap filters when it's hard to breathe through.

What is available to you depends on were you live, in Europe it is more usual to find 6035 P3R cardridge, in america and asia it is more usual to find 7093 N100 cardridge, they both almost the same when it comes to filter efficiency, were 6035 can filter 99,95% and 7093 can filter 99.97% of particles at 0.3 micrometers or below. Both are essentially a plastic casing containing a HEPA filter, unlike N95 or those round filters were all particles in the air or water droplets is caught on the filter, since these are essentially naked, with housings, water droplets only hit the the outer housing and only air that you actually breath is filtered, so it lasts longer, additionally you can clean the outer plastic casing with 70% isopropyl, since cleaning a filter itself would permanently damage filtering capability. After a while of using these filters, they will actually become better at filtering as particles are caught and work as some additional wall, but after a while breathing becomes harder, were after some time you want to replace them if it becomes too hard to breath. If you need additional protection when working with, lets say paint or insecticide, 6038 is the same as 6035 in the sense sense it contains a P3R filter, but adds a carbon filter, so it can filter gas and vapor's, the equivalent outside EU would be 60921. There are many more types of filters or combination filters available for different jobs and needs, P3R is good for particles, but can't block gasses and vapor's or formalyde or mercury or chlorine. Basically, choose the right filter(s) for the job so you don't die or get hospitalized. But remember if you need just 1 filter, if you buy combination filters, you are just spending 2-3* more money for filtering you don't actually need. Also remember that reusable masks that have a outlet/valve do not filter air that goes outside, so if you work with patients, vulnerable, old people, you can infect them or make them sicker if you happen to be infected with SARS-CoV-2. Instead you should be using FFP3 (EU) or N95 (outside EU) masks without any valve, were both air in/out are filtered, but note that these masks are designed for 1 time use so you should bin them after the job...if you have no choice though, i guess you could decontaminate if heated in a oven at 70°C for 30 minutes, but after every reuse, filtering efficiency will lower until it becomes a risk to use... ...you could also try cut a surgical mask and aditionally take layers that block germs and stuff, then place that layer at the outlet/valve, but i am not sure if that actually works and if it might impede breathing or silicone flap of the mask. And lastly, depending on what job you are doing, you should think of wearing safety glasses (air sealing without valves and with anti-oxidation layer) if you are using half face respirators, as your eyes are probably also a vulnerable spot. Here is a PDF from 3M regarding advice for corona viruses: multimedia.3m.com/mws/media/1793959O/cleaning-and-disinfecting-3m-reusable-respirators-following-potential-exposure-to-coronaviruses.pdf

Shika Hookah the mask sucks down, you definitely feel it. I'm ex military, that's how we do it with the NBC gear and it's the same here just the exact mask and filter is different

2 ways. Negative pressure fit check: cover the intake of the filters, inhale sharply. If your face mask collapse, and you can't breathe, that's good seal. Positive pressure. Some filters have very large openings and you can't cover it with your palms. Cover the exhale valve and breathe out. Your mask should inflate and you don't feel any air escaping.

@@noth606 NBC filters typically have "reduced openings" so a plug can be used to seal it when not in use and you can easily do a negative pressure user fit check by breathing in while covering the small filter intake with your palm. Industrial filters have large openings and 3M have disc filters; this is to reduce breathing resistance. You can't cover the opening sometimes so it's very difficult to do a negative pressure user fit check. Alternatively, don the mask without filters, do a negative pressure user fit check on the connectors, then mount the filters. So instead, they should do a positive pressure user fit check, by breathing out while covering the exhale valve. The mask should inflate. You don't wanna breathe in first to do a user fit check in an NBC environment with someone shouting "gas, gas, gas" right? However, this also means that they can't check the connection between the filter and the mask (which may have some leaks if not screwed in properly or a washer is loose or something) or the integrity of the filter cartridge (imagine it having a crack on the body).

V T good points, how to do a seal check does depend on the filter type and mask, I was a bit too general. But I know from other comments on other threads that he is referring to a 6800 but I'm not sure which filters he has. I'm using 6035's which makes it very easy to do a negative seal check as they close up if you press on them but that is only true for a few specific 3M models, and the disc type ones would probably require a positive pressure seal check. When I was in the army doing a seal check in a "Gas! Gas! Gas!" Type scenario was mostly optional, we did it more when we were learning the procedure to get the mask and gear on quickly. But a lot of guys didn't put the masks on properly and when they threw military concentrated CS into the mix we had a lot of vomit filled masks lol, not a very good look.

staffnsnake thank you.

1. Not all of India is tropical. 2. Loads of people are using them in Indonesia and the Philippines.

10s No. the seal has nothing to do with the hood as it is around the edges of the face. But more importantly, for safe doffing, the respirator must be the last thing to come off and that is done outside the red zone.
