A thread on ambulance ventilation.

And why you are going to see more staffing EMS staffing shortages - resulting in you laying forever next to your wrecked car.

Waiting to be picked up by CoVid+ EMT's in surgical masks.
Study is here - click the PDF button....or just ride along in this clown car.
researchgate.net/publication/33…

Looks like in the USA, there are no standards for ventilation in ambulances.

Used to be 30 ACH..which would be amazing.
In the UK, they recommend not using the recirculating air during AGP's, during pandemics.

assets.publishing.service.gov.uk/government/upl…

Currently, surgical masks as long as within 6 feet of the CoVid+. No recirculating.
gov.uk/government/pub…

All based on WHO guidance. (Foreshadow.)
The default ventilation of the ambulance is 5 ACH, IF the exhaust blower was on.

They replaced the default ventilation tho with the below HEPA filter, so they could get accurate measurements, avoiding external aerosols, and reset quickly.

Quite clever.
americanlaboratorytrading.com/lab-equipment-…
Here's the rest:

"For each test, four optical particle counters
(OPCs) were placed in locations representing possible positions for a seated EMS worker treating the
patient. OPCs were placed in the positions labeled OPC 1-4 when the cot was at 0° or 30°, and positions ..."
Before going on, let's touch on the 5 ACH that all of you will be hit with in surgical masks.

Even with surgical masks on, we have certainly seen a huge number of outbreaks in hospitals with 6 ACH (better) ventilation
and continuous surgical masking.

For example, Alberta Health Services, @AHS_media, which is the embodiment of the @WHO's IPC guidance.

Stands to reason as Dr. Conly rules over AHS AND the WHO with a very clean fist.

Back to our clown car, Lindsley (yep, the famous one) found that a single cough resulted at least some worker exposure.

Given that Delta is everywhere, and we now know it takes under 3 virii to successfully infect?

Not good.

Might not be a bad idea to buy a @FixTheMask brace
in case you have to go to the hospital or even ride in an ambulance.

Or make the 3 rubber band version and keep it in your wallet or purse:


Why would there still be exposure?

"Air circulation pattern in the ambulance patient compartment generated by...
the ventilation
system. The jet of air created by the air inlet causes a clockwise recirculation pattern to form which
circulates aerosol particles throughout the compartment. Even if the cough is directed toward the rear
of the ambulance, aerosol particles are carried
toward the front by the recirculation. Thus, a worker
anywhere in the ambulance is exposed to the cough aerosol particles."

Thus, you will be exposed to the same.

But does it have to be this way?

No. Or I should say, N100.

The same solution as in this thread that was
slightly viral about 25 years of no infection in the Texas TB hospital:


And the same solution being used today by NYC's EMS:
nydailynews.com/new-york/ny-fd…
But the story does not end there.
Did you know that someone tried putting a HEPA filter into an ambulance?

cdc.gov/niosh/hhe/repo…

"The effective
air change rates ranged from about 43 to 46 ACH in
the HEPA ambulance, and from 26 to 32 ACH in the
non–HEPA ambulance."

This provides further proof that
portable air cleaners such as the Corsi/Rosenthal Box are additive to any current air cleaning infrastructure.

And...they help remove aerosols much faster.

The message is the same because this is NOT rocket science.

Vax.
N100.
HEPA if you can afford it.
CR Box if you can't
A very cool simulation model study confirming what Dr. Noakes shared below. Thank you!

1 - An ambulance transport with a patient actively emitting a virus.
2 - A subsequent transport with an uninfected patient <- very interesting setup here.

How do we know TB is airborne?

71 guinea pigs gave their lives between 1956 and 1958 in the eponymous study by Riley et al, getting TB air piped in from some TB patients, to prove TB is airborne.

Influenza is kind of airborne per most doctors. But kind of not.

So....

We need some volunteers.

Will horses be those volunteers that finally lay it all out?

Yes - but none of them lost their lives.

Air samplers were deployed and tracked horses inoculated with Equine influenza virus (EIV).

From the very first day post inoculation (dpi), until the Image
12th day, EIV was found in the air, in this new study.

With no horses, or guinea pigs, hurt in the process.



But sure, influenza's not airborne - if you are the USDA, right, @nirav_maine?

Of course, yet another new study points an accusatorysciencedirect.com/science/articl…

Thank you @BarryHunt008 for flagging this.

@ThailandMedicaX, retweeted by some because of their controversial takes (ahem, their lies?), is saying that FAR-UVC is dangerous because somehow the light will get into the lungs.

Lol.

They are just apparent supplement grifters.

I noticed they were using @NukitToBeSure's excellent torches as their example picture.

Strange to be so selective of an example picture for someone purporting to be an independent news source on health.

Hmm. I helped defend Nukit against charges of Image
racism by a very nasty couple who it turned out just do not like UVC, personally. I wonder....

Yep, ThailandMedicalX has blocked me.

But, it's weird for a purported news source to block someone like me @gorskon
@doritmi @19joho.

And them blocking me, is probably because Image

You've heard of "The Three Problem." - great book, and excellent Netflix series.

If you want to be avoid catching Covid, you probably have "The Empty Room" situation in the back of your mind.

How long after a room had people in it, can you safely demask?

Thread.

Measles was thought to be airborne after a child caught measles an hour after the infected child left the same office.

.

Interestingly, you can see the reluctance in blue below to call measles airborne. Much like the WHO with @mvankerkhove researchgate.net/publication/19…In February 1981, a measles outbreak occurred in a pediatric practice in DeKalb County, GA. The source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. On examination, he was noted to be coughing vigorously. Seven secondary cases of measles occurred due to exposure in the office. Four children had transient contact with the source patient as he entered or exited through the waiting room; only one of the four had face-to-face contact within 1 m of the source patient. The...
which spent millions to rebrand SARS2 as "through the air" rather than airborne.

It is an inconvenient truth that then leads us to the study showing an #EmptyRoom SARS2 infection at 1 hour and 43 minutes, and FOUR HOURS and FORTY-FIVE MINUTES.

In this study, it comes with Experimental evidence suggests that SARS-CoV-2 remains viable within aerosols with a half-life of approximately 1-3 hours, though changes in aerosol microenvironment may shorten viability to minutes. However, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing of nasopharyngeal samples obtained from patients on an outbreak unit suggested in-room transmission of the delta variant, AY3 lineage, of SARS-CoV-2 to two patients admitted 1 hour, 43 minutes and 4 hours, 45 minutes after discharge of an asymptomatic infected patient. These findings suggest...

Mum's the word - if @SecKennedy is Mum.

You see, I have been a VERY FOCAL CDC critic. But you can't criticize without listening.

And I have been noticing that that the CDC has been very, very quiet.

NPR noticed as well. Image
This is crazy. Image
Yes, the @CDCgov has been deathly quiet.

90 times last year, versus 4 this year.

This is not MAHA.

This is MASA - Make America Silent Again.

And as one of the CDC's most focal critics? We NEED them to be sharing Public Health information. Image

I have a new thing to say to why I mask.

Ronald Reagan, Michael J Fox, Robin Williams, Lou Gehrig, Bruce Willis.

Alzheimer's, Parkinsons, Lew Body Dementia, ALS, CJD

All of them are dying or are dead from - the common cold.

You see,
One of the main viruses that results in the cold is a virus called OC43.

And it turns out that it's neuroinvasive - and is strongly associated with all of those diseases.

Even though it's just a cold in the beginning. So, those are 5 really bad diseases that I am protecting
myself from.

Kind of like HIV is often just like a cold or a mild case of flu in the beginning.

So, yeah, I mask so I don't catch a cold.

Or Covid - which is also neuroinvasive, and let me tell you all about the horrible things it does to your body much quicker....

Safer showering and swimming with great breathability!

Others have used a snorkel w/ N95s - but those then collapse around the snorkel, and breathability is more restricted. This new approach is w/ an internal BRACE!

I took a shower with this, and it worked perfectly. Build 🧵 Image
This is a great technique, but I was looking for something with more breathability.

Image
This is the internal brace, and how the magic happens.

My subconscious must have picked this up from surgical mask braces that go under surgical masks.

So, here's the build. Image
