N-95 respirator masks are the newest hot selling item for “flu preparedness”, but do they really work? Yes. And No. N-95 respirator masks were made to protect healthcare workers from `airborne` illnesses including tuberculosis, chicken pox as well as the flu. They DO work under tightly controlled circumstances, nevertheless the general 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 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 just ostracized. With the swine flu claiming increasingly more victims in the US, people are starting to react by putting on masks again. But this time, the larger technology N95 For Sale is very popular.
The N-95 is NOT your grandfather`s surgical mask or even the same as surgical masks worn by doctors and nurses today like the thing is in operating rooms. These are specialized items which were made to protect hospital workers against `airborne` illnesses like tuberculosis, chicken pox and influenza. All of these are very 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 claim that they don`t. So what is the reality?
The reality is that N 95 respirators DO protect wearers up against the flu- a minimum of theoretically and 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 nearly doubly large at approximately 80-120 nanometers. In 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 these tiny particles
But there are numerous main reasons why the N-95 respirators are unlikely to work for that general public. The initial reason is that it is tough to have the right fit. Medical care workers who wear N95 Face Masks For Sale are told, “Here, put this on”. Surgical masks can be worn by anyone, anywhere for long time periods. As shown by people in China wearing masks while riding bicycles to work or even jogging, these are pretty comfortable and easy to use. But a health care worker who uses an N-95 must actually proceed through a short training session. First, the approximate correct size for your face is chosen and placed tightly on the face with 2 tight straps fitting to the head. Second, the metal band on the nose bridge is smoothed down to acquire a tight fit. When a correct fit is approximated, the head is placed into a large plastic tube to approximate a confined space. A trainer, normally a nurse, sticks a spray bottle into a small hole and continuously sprays a saccharine solution in to the plastic tube as the wearer turns the head from side to side and up and down to ensure that you will find no air leaks. In the event the saccharine solution is tasted, then the good `fit` has not been obtained and the process is repeated with another sized mask until an airtight seal is obtained: sometimes challenging for those that have particularly small or large faces or individuals who have facial hair.
The second reason is the fact that N 95 Respirators are uncomfortable, hot and tight. While a surgical mask can be worn for several hours without the problems, an N-95 respirator becomes uncomfortable and claustrophobic even in a cool hospital room within just minutes. After taking care of someone for even a quick 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 just like you entered into a cool fresh breeze after just getting out of a sauna. Wearing one out of an air conditioned theater while just sitting and watching a film could be unbearable. Wearing one while riding a bicycle or while shopping would be just simply impossible.
Any mask- whether it be surgical or N95 Mask For Sale is made to be utilized for under twenty or so minutes at the same time. It is because the mask itself will become saturated with condensation from exhaled breath. And once it is saturated, then this gaflvq filter size may be changed making the mask ineffective and potentially even trapping the offending viruses right from the wet mask- Right Near the Face!
So, while N-95 masks DO effectively protect healthcare workers from even one on one transmission of airborne contaminants like the flu, inappropriate usage by untrained lay people in real life circumstances would likely make sure they are ineffective and nullify the potential protective outcomes of these effective filtration devices.
