Kn95 Masks – Are They Worth It?
Various studies have found that healthcare workers should use non-medical or minimally-invasive masks, such as the KN95 mask, or any other approved mask, as a first-line treatment option for people who suffer from COPD (chronic obstructive pulmonary disease).
Of these, the most important benefit is the improvement in breathlessness and wheezing, two symptoms associated with advanced COPD. The device improves fit and shape, reduces airway resistance, and can be used while breathing either with the mouth or without the mouth. This ensures that the user can breathe in a normal fashion, avoiding the potential for airway compromise, which can be life-threatening.
However, further study is needed to confirm that this type of medical procedure mask, properly fitted and used, has benefits beyond improving breathlessness and wheezing. There are additional considerations to make when selecting this alternative facemask for COPD treatment.
Fit & Size
In addition to the fit, the size of the masks is a crucial factor. As discussed in the previous section, tighter fitting masks improve airway compromise by reducing airway width. It is therefore important that these masks not only fit snugly but also not leave gaps around the edge.
Similarly, while some may consider ear plugs to be a necessity, the fact is that without the presence of these plugs, gaps around the ear loops could compromise the seal of the masks.
Another possible concern with using cloth face coverings for this purpose is the increased chance of abrasion against the face. The wearing of these masks during routines such as bathing or cleaning the house may result in abrasion against the face. If you already have a history of facial injuries, it would be wise to wear protective gear even without these masks. A better fit is more important than protection.
Limitations
There are several reasons why these masks made from special fabric face coverings fail to provide the best fit and superior protection.
The first is that they do not contain enough spaces to allow for proper airflow. Since the face is sealed, there is no way for air to circulate. The result is that carbon dioxide builds up in the lungs. Since the body cannot exhale carbon dioxide, the patient begins to feel uncomfortable. The wearing of masks made of cloth will allow the exchange of fresh oxygen and carbon dioxide, thereby ensuring better health.
The second problem is that these cloth masks contain small gaps. While some sheets are hypoallergenic, many patients still get discomfort from them. If the doctor has to use multiple layers of tape to seal the gaps, then he or she will have to sew them using a very sharp needle.
Another issue is that the kn95 masks made from special fabric face coverings do not meet requirements similar to those of standard respiratory respirators. This means that the masks should not leak.
They are also known to have poor air circulation. For patients who suffer from COPD and respiratory failure, this should be of great concern.
Things to take care of
It is important to note that some of the most stringent federal health and safety guidelines for facial surgery (such as the Food and Drug Administration’s) do not apply to the use of either disposable or reusable knutsford or n95s. In fact, it is illegal to use any mask that does not have a label that states that it meets federal guidelines. This law was put into place in response to the numerous counterfeit masks that were being sold online to patients who believed that they were purchasing authentic products. In order, to be safe from such frauds you can visit authentic websites such as accumed.com
Lastly, the material used to make the plates of Knutsford or N95 masks has changed over the years. Originally, the material was composed of five layers: an ultra-light polyester mesh, a heavy grade Nylon fabric, and a layer of high-density polyethylene. Today, the material that is used has improved significantly, but the five layers still play an important role. Surgeons use the material to prevent particles from entering through the eye area. In addition to this, the five layers provide the surgeon with the necessary strength to keep the chin, nose, and mouth in proper alignment while performing his or her job.
