There seems to be a great deal of confusion and misinformation circulating about "respirators", who has them, who doesn't, who makes them and what
they're used for. Much of this stems from a basic misunderstanding about what a "respirator" is.
The respirators which save sick people's lives in hospital intensive care units (ICU's) actually aren't "respirators" at all, they are "ventilators".
And, companies like FORD and GM are NOT making "ventilators", they're making "respirators". They're different, have different applications and
uses.
In it's most basic form, a "respirator" is simply a device (usually a mask of some form) which protects the wearer from breathing in particles, gases,
chemicals or pathogens which may be in the air around them. They have nothing to do with saving a sick person's life, and have everything to do with
preventing otherwise healthy persons from becoming ill, injured or otherwise compromised due to inhaling harmful airborne particles or substances.
A "ventilator", on the other hand, is a mechanical device which mechanically provides oxygenated air into the lungs as well as removes CO2 saturated
(spent) air from the lungs. This is done generally by inserting a tube down the throat, through the trachea and into the airways to the lungs through
which air is supplied and removed from the lungs.
When people say "Hostpitals are critically short of respirators", this is a misleading statement. Hospitals are critically short of both
'ventilators' AND 'respirators', BUT...it is 'ventilators' which are so critically important to saving lives. "Respirators" only protect the staff
and others from becoming sick. Both are critically important, but they serve entirely different purposes.
So what exactly are companies like Ford and GM making for the medical industry? In short, they're making "respirators", not "ventilators" which are
exponentially more complex and difficult to make. You see, in the world of respirators at the low end you start with something as simple as a dust
mask, and as the chemicals, toxins or pathogens increase so does the level of filtering. At the higher ends of 'respirators' you have devices known
as positive air pressure respirators. What this means is that filtered air is supplied inside of a contained area to create a positive air pressure
which is higher than the area surrounding it, thus the person wearing such a device only breathes the pressurized and filtered air and not the ambient
air around them. THIS is what the Ford's and GM's of the world are producing, NOT ventilators.
Which brings us finally to the subject of a "surgical mask". This too is a form of respirator, but it's function is actually the exact opposite of a
regular respirator. A surgical mask prevents particles, pathogens, etc. from being passed FROM the wearer TO someone else, say a person on an
operating table, or in a dentists office, who is susceptible to infection.
So here's the takeaway from all of this:
1. Critically ill COVID-19 patients need "Ventilators", NOT "Respirators. These are in critically short supply, and very few companies make them.
2. Medical staffs (Doctors, Nurses, EMS, etc) need "Respirators" to protect them from patients who may be infected with a disease such as COVID-19.
These are also in critically short supply, but lots of companies make them, including now Ford and GM for the positive pressure versions.
3. The general population is being asked by government officials to wear "surgical masks", not to protect them, but to prevent THEM from transmitting
the disease to someone ELSE.
SHAME on the MSM and so many others, government officials AND the medical community included, for not making this matter crystal clear to everyone!
That is all.
