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 and the flu. They DO work under tightly controlled circumstances, but the general public is not apt to be in those tightly controlled circumstances, so they will likely not take advantage of them.
Face masks were first used through 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 put them on were considered “mask slackers” who could be fined, imprisoned or simply ostracized. With the swine flu claiming a lot more victims inside the US, people are starting out react by putting on masks again. But this time, the greater technology Coronavirus Masks For Sale is all the rage.
The N-95 is NOT your grandfather`s surgical mask or maybe the same as surgical masks worn by doctors and nurses today just like you see in operating rooms. These are specialized pieces of equipment which were designed to protect hospital workers against `airborne` illnesses like tuberculosis, chicken pox and influenza. All of these are extremely small infectious particles that remain airborne after being exhaled by an infected person. There has been lots of misinformation about these masks. Some claim that they work, some state that they don`t. So what is the truth?
The fact is that N 95 respirators DO protect wearers from the flu- at least in theory and when used properly. The N 95 respirators ARE Airtight and Are made 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 practically two times as 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 VERY EFFECTIVE at preventing transmission of such tiny particles
But there are numerous explanations why the N-95 respirators are unlikely to get results for most people. The initial reason is that it is hard to have the right fit. Health care workers who wear surgical masks are told, “Here, put this on”. Surgical masks may be worn by anyone, anywhere for too long periods of time. As shown by individuals China wearing masks while riding bicycles to work as well as jogging, they are pretty comfortable and user friendly. But a health care worker who uses an Coronavirus Masks For Sale must actually proceed through a short training session. First, the approximate correct size to your face is chosen and placed tightly to 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. When a correct fit is approximated, the top is positioned into a large plastic tube to approximate a confined space. A trainer, often a nurse, sticks a spray bottle in to a small hole and continuously sprays a saccharine solution to the plastic tube whilst the wearer turns the head back and forth and all around to make sure that there are no air leaks. When the saccharine solution is tasted, then this good `fit` has not been obtained and the procedure is repeated with another sized mask until an airtight seal is obtained: sometimes difficult for individuals with particularly small or large faces or anyone who has facial hair.
The second reason is the fact that N 95 Respirators are uncomfortable, hot and tight. While a surgical mask may be worn for many hours with no problems, an N-95 respirator becomes uncomfortable and claustrophobic even during a cool hospital room in just minutes. After taking care of someone for even a short while, the breath feels hot and uncomfortable and a lot commence to sweat- some people sweat PROFUSELY! Removing the mask after wearing one for just a short while feels just like you entered into an excellent fresh breeze after just getting away from a sauna. Wearing one inside an air conditioned theater while just sitting and watching a film would be unbearable. Wearing one while riding a bicycle or while shopping could be simply impossible.
Any mask- be it surgical or Coronavirus Masks For Sale is designed to be applied for less than twenty or so minutes at a time. The reason being the mask itself can become saturated with condensation from exhaled breath. And as soon as it is saturated, then wzxegl pore filter size may 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 one on one transmission of airborne contaminants such as the flu, inappropriate usage by untrained lay people in real life circumstances would likely make them ineffective and nullify some of the potential protective effects of these effective filtration devices.
