Article Summary 英语Essay代写学术文章
In the article, “Is there an adequate alternative to commercially manufactured face masks? A comparison of various materials and forms”, Teesing et al. (2020) have attempted to find out the alternative face masks that a population could wear during the shortage of medical face mask using the readily available material keeping in view the effectiveness of the face mask in protection against SARS-CoV-2. For this purpose, the authors have modeled a face mask using the readily available material and compared them with KN95/N95/FFP2. The world is already going through a shortage of medical-grade protective equipment. Many governments have made it compulsory to wear facemasks.
To carry out the comparison, a filter is selected from the literature and by finding out the no-woven fabrics. They considered commercial air filter fabric which was considered a viable option. However, materials that are frequently used in the healthcare system are avoided in order to avoid the shortage of such material in healthcare. The opted material is then tested (Teesing, Straten, Man, & Horeman-Franse, 2020, p. 247). In the methodology, the first step is the particle test. The procedure was based on the baseline measurement where free-flowing air was passed through the particle chamber.
This process was repeated three times to make sure that the loose particles which remain adhere to the fabric do not intervene in the filtration measurement. 英语Essay代写学术文章
In this way, the ratio of particles is calculated. The next step of the procedure was a fit test which emphasized that the safety of the mask also depends upon how it fits the face as the mask must be able to prevent the entrance of air from the top and the sides. To proceed with this step, AccuFIT 9000 Respirator Fit test apparatus is used. In this step, they have tested various models such as round, folded, duckbill, and pleated. The next step is a pressure test, hydrophobic test, wash test and determination of needed population compliance (pp. 249-250).
It is deduced that quilt fabric with two layers with the filter made up of household paper towels can be a feasible and sustainable choice. It is the best choice for protecting the population as it is cleanable and widely available. However, none of the masks have been found to pass the fit test due to leakage. Moreover, it is found that masks make up of quilt form are not hydrophobic. Another important finding was that a cotton mask without a filter is not effective enough and does not attain the purpose of preventing the reproduction of the virus. The tests conducting in this study are more precise than the European standards which might not be optimal for SARS-CoV-2. In the end, this study significantly abets the use of commercially manufacturing filters as a substitute for masks (p. 251).
