N-95 respirator masks are the newest hot selling item for “flu preparedness”, but will they work? Yes. With No. N-95 respirator masks were created to protect healthcare workers from `airborne` illnesses like tuberculosis, chicken pox and 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 likely not benefit from them.
Face masks were first used during the 1918 flu epidemic as `protection` up against the flu. It likely did not do any good, but laws were enacted and people who didn`t put them on were considered “mask slackers” who might be fined, imprisoned or simply just ostracized. With the swine flu claiming increasingly more victims within the US, people are beginning to react by putting on masks again. But this time, the larger technology Masks For Covid-19 is very popular.
The N-95 is not really your grandfather`s surgical mask or perhaps the same as surgical masks worn by doctors and nurses today as if 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. All of these are incredibly small infectious particles that remain airborne after being exhaled by an infected person. We have seen plenty of misinformation about these masks. Some claim that they work, some say that they don`t. So what exactly is the reality?
The fact is that N 95 respirators DO protect wearers against the flu- a minimum of in theory so when used properly. The N 95 respirators ARE Airtight and Are Designed to protect the wearer from airborne particles as small as Mycobacterium Tubuculosis- approximately 45 nanometers in width or about 1/2 micron. The swine flu virus, by contrast, is almost doubly large at approximately 80-120 nanometers. Within the hospital setting when utilized by trained practitioners, as set by Centers for Disease Control guidelines, these masks are amazing at preventing transmission of such tiny particles
But there are several reasons why the N-95 respirators are unlikely to get results for most people. The very first reason is that it is tough 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 too long amounts of time. As shown by people in China wearing masks while riding bicycles to function as well as jogging, they are pretty comfortable and user friendly. But a health care worker who uses an Face Masks For Coronavirus must actually go through a brief workout. First, the approximate correct size for the face is chosen and placed tightly on the face with 2 tight straps fitting on the head. Second, the metal band on the nose bridge is smoothed down to get a tight fit. Once a correct fit is approximated, the head is placed right into a large plastic tube to approximate a confined space. A trainer, normally a nurse, sticks a spray bottle right into a small hole and continuously sprays a saccharine solution in to the plastic tube whilst the wearer turns the pinnacle back and forth and all around to ensure that you will find no air leaks. If the saccharine option is tasted, then the good `fit` is not 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 individuals who have facial hair.
The next reason is that N 95 Respirators are uncomfortable, hot and tight. While a surgical mask may be worn for hours without any problems, an N-95 respirator becomes uncomfortable and claustrophobic even in a cool hospital room within just minutes. After caring for someone for even a short while, the breath feels hot and uncomfortable and many begin to sweat- many people sweat PROFUSELY! Removing the mask after wearing one for just a brief while feels just like you entered into a cool fresh breeze after just getting away from a sauna. Wearing one in an air conditioned theater while just sitting and watching a motion picture will be unbearable. Wearing one while riding a bicycle or while shopping could be just simply impossible.
Any mask- whether it be surgical or N95 Masks For Sale was created to be applied cheaper than 20 minutes at a time. This is because the mask itself will become saturated with condensation from exhaled breath. And once it really is saturated, then wzxegl pore filter size may be changed making the mask ineffective and potentially even trapping the offending viruses right up against the wet mask- Right Near the Face!
So, while N-95 masks DO effectively protect health care workers from even one on one transmission of airborne contaminants like the flu, inappropriate usage by untrained lay folks real-world circumstances would likely get them to ineffective and nullify the potential protective outcomes of these effective filtration devices.
