Face Masks For Coronavirus..
N-95 respirator masks are the newest hot selling item for “flu preparedness”, but do they work? Yes. With No. N-95 respirator masks were designed to protect healthcare workers from `airborne` illnesses including tuberculosis, chicken pox as well as the flu. They DO work under tightly controlled circumstances, but the public is not apt to be in those tightly controlled circumstances, so they will more than likely not take advantage of them.
Face masks were first used throughout the 1918 flu epidemic as `protection` up against the flu. It likely failed to do a bit of good, but laws were enacted and people who didn`t use them were considered “mask slackers” who could be fined, imprisoned or simply just ostracized. Using the swine flu claiming increasingly more victims in the US, individuals are starting to react by putting on masks again. But this time around, the higher technology Masks For Coronavirus is all the rage.
The N-95 will not be your grandfather`s surgical mask or maybe the same as surgical masks worn by doctors and nurses today like you see in operating rooms. They may be specialized items which were made to protect hospital workers against `airborne` illnesses like tuberculosis, chicken pox and influenza. Most of these are very small infectious particles that remain airborne after being exhaled by an infected person. We have seen a lot of misinformation about these masks. Some say that they work, some state that they don`t. So what is the reality?
The truth is N 95 respirators DO protect wearers from the flu- at the very least theoretically and once used properly. The N 95 respirators ARE Airtight and Are made to protect the wearer from airborne particles no more than Mycobacterium Tubuculosis- approximately 45 nanometers in width or about 1/2 micron. The swine flu virus, by contrast, is nearly two times as large at approximately 80-120 nanometers. In the hospital setting when employed by trained practitioners, as set by Centers for Disease Control guidelines, these masks are VERY EFFECTIVE at preventing transmission of such tiny particles
But there are several explanations why the N-95 respirators are unlikely to work for most people. The very first reason is it is difficult to get the right fit. Health care workers who wear surgical masks are told, “Here, put this on”. Surgical masks can be worn by anyone, anywhere for very long time periods. As shown by people in China wearing masks while riding bicycles to work or perhaps jogging, they may be pretty comfortable and user friendly. But a health care worker who uses an N95 Masks For Sale must actually go through a short workout. First, the approximate correct size to your face is chosen and placed tightly on the face with 2 tight straps fitting onto the head. Second, the metal band in the nose bridge is smoothed down to get a tight fit. After a correct fit is approximated, the head is put into a large plastic tube to approximate a confined space. A trainer, usually a nurse, sticks a spray bottle into a small hole and continuously sprays a saccharine solution into the plastic tube while the wearer turns the top from side to side and all around to make sure that you can find no air leaks. In the event the saccharine option is tasted, then a good `fit` has not been obtained and the procedure is repeated with another sized mask until an airtight seal is obtained: sometimes hard for individuals with particularly small or large faces or anyone who has facial hair.
The 2nd reason is the fact that N 95 Respirators are uncomfortable, hot and tight. While a surgical mask can be worn for several hours without any problems, an N-95 respirator becomes uncomfortable and claustrophobic even in an awesome hospital room within just minutes. After caring for someone for a short while, the breath feels hot and uncomfortable and most start to sweat- some people sweat PROFUSELY! Taking off the mask after wearing one for just a short while feels like you entered into an excellent fresh breeze after just getting out of a sauna. Wearing one in an air conditioned theater while just sitting and watching a film would be unbearable. Wearing one while riding a bicycle or while shopping will be simply impossible.
Any mask- whether it be surgical or N95 For Sale is made to be used for less than twenty minutes at the same time. It is because the mask itself will end up saturated with condensation from exhaled breath. And when it really is saturated, then wzxegl pore filter size could be changed making the mask ineffective and potentially even trapping the offending viruses right against the wet mask- Right Near the Face!
So, while N-95 masks DO effectively protect health care workers from even in person transmission of airborne contaminants including the flu, inappropriate usage by untrained lay folks real world circumstances would likely make sure they are ineffective and nullify any of the potential protective results of these effective filtration devices.
