Abstract :
Conflicting recommendations exist related to which facial protection should be used by health care workers to prevent transmission of acute respiratory infections, including pandemic influenza. We performed a systematic review of both clinical and surrogate exposure data comparing n95 respirators, cloth mask and surgical masks for the prevention of transmissible acute respiratory infections. Masks became quite the necessity for a good part of these year, and will continue to be for several coming months at least. To know the quality of protection, we searched in various electronic databases and the grey literature for relevant studies of n95 respirators, ordinary and surgical masks, by testing the samples and predicting the statistical status from the data survey (collecting the questionnaire) and conclude the effectiveness protection of the mask through the result. From the analysis that has been examined the efficacy of ordinary, medical masks and respirators in protecting against respiratory infections could be determined. The benefits and risk of using the mask can be justified with proper testing and predicting the statistical status from the data survey. Respiratory protective masks are used whenever it is too costly or impractical to remove airborne contamination from the atmosphere. Respirators are used in a wide range of occupations, form the military to medicine. Respirators have been found to interfere with many physiological and psychological aspects of task performance at levels from resting to maximum exertion. Many of these limitations have been investigated in order to determine quantitatively how much performance decrement can be expected from different levels of respirator properties. The entire system, including respirator and wearer interactions, must be considered when evaluating wearer performances. This information can help respirator designers to determine trade-offs or managers to plan to compensate for reduced productivity of wearers.
