In a letter to the Principal Secretaries of well being and medical schooling of states, Rajiv Garg, the Director-Common of Well being Companies (DGHS) not too long ago identified the “inappropriate use” of N-95 masks with valved respirators by the general public.
“It is to bring to your knowledge that the use of valved respirator N-95 masks is detrimental to the measures adopted for preventing the spread of coronavirus as it does not prevent the virus from escaping out of the mask,” Garg wrote within the letter.
Why it’s best to keep away from sporting N-95 masks with valves
Medical doctors have been discouraging the usage of N-95 masks with exhaled valves in patient-management, stated Dr Vikas Maurya, director & head, division of pulmonology & sleep problems, Fortis Hospital, Shalimar Bagh, New Delhi. “If a COVID-19 patient is exhaling through the valve in the mask and there is another person in front wearing only a cloth mask, it does not really eliminate the risk of being infected. So at our hospital, we ensure people in the COVID wards are wearing normal N-95 masks without valves,” he added.
