The Centers for Disease Control and Prevention (CDC) recommends wearing masks to slow the spread of the coronavirus, but for those who wear disposable masks, they often encounter a question: can they re-wear disposable masks such as ffp2 masks and surgical masks? In short, yes, but only if you take care of them properly. Can ffp2 mask be cleaned and ow to clean ffp2 mask?
This passage contains the followings of how to clean ffp2 mask:
(1)What is ffp2 mask?
(2)Reuse ffp2 masks
(3)Indications of Ffp2 mask
Ffp2 mask is a full-face mask with or without valve. These masks are designed to protect medical staff from coronavirus and other pathogens that are spread through the respiratory tract. So-called surgical masks were not included in this survey. These are masks worn by care providers during procedures such as surgery to protect the patient from microbes from the care provider on the one hand, and to protect the care provider from blood spatter on the other hand.
Ffp2 masks refer to masks that meet the European (CEEN149:2001) standards. The European standards for protective masks are divided into three levels: FFP1, FFP2, and FFP3. The difference from the American standard is that its detection flow rate is 95L/min and DOP oil is used to generate dust.
The Dutch National Institute of Public Health and Environment (RIVM National Institute of Public Health and Environment) conducted a pilot study and found a reprocessing method that can make the quality of reprocessed masks reach an acceptable level. It should be noted that there are few studies on the retained particles of reprocessed masks. This study shows that Ffp2 masks can retain their shape and retain particles in a "quick" test after being sterilized once and twice with a short hydrogen peroxide process. When it is scarce, if it is sterilized twice with hydrogen peroxide between uses, the Ffp2 mask can be used 3 times.
The FFP2-type protective filtering masks must be reserved exclusively for HCWs when performing invasive medical procedures or manoeuvres on the respiratory tract that may generate an aerosol: intubation/extubation/laryngeal mask, invasive ventilation with open-expiratory circuit, non-invasive ventilation, endotracheal aspiration, bronchial fibroscopy, aerosol therapy, aerosol-generating chest physiotherapy (bronchial decongestion, induced sputum, etc.), nasopharyngeal sampling, functional respiratory explorations, dental surgery procedures, autopsy or other procedures at risk of aerosol.
Any strategy to deal with an influenza pandemic must be based on knowledge and tools at the time of the pandemic. In the short term, when we lack adequate supplies of vaccines and antiviral drugs, the strategy of relying on social isolation and physical barriers as a means of preventing the spread of diseases will be relatively more prominent. The use of respirators and masks is a key part of a larger strategy to build barriers and increase the distance between infected and uninfected people. Respirators and masks may have a role in both clinical care and community settings.
