Due to the COVid-19 pandemic, medical mask and EN149 ffp2 mask are widely recommended for a large number of individuals and long durations. The effect of wearing a surgical and aN en149 FFP2 protective mask on cardiopulmonary exercise capacity has not been systematically reported.
Following the outbreak of the COVid-19 pandemic, the use of face masks (FM) is widely recommended by international, national, and local authorities. The aim of the regulations is to reduce the respiratory droplet excretion in pre-symptomatic and asymptomatic individuals (source control). The evidence for face masks to reduce respiratory virus infections or to improve clinical outcomes is heterogeneous. The role of fine-particle aerosols and environmental factors such as temperature and humidity on respiratory virus transmission is a matter of scientific debate. However, as long as no effective treatment or vaccination against COVid-19 is available, health policies need to rely on non-pharmacological interventions such as social distancing, intensified hand hygiene, and the wearing of face masks. Current recommendations to wear an ffp2 protective mask during times of contact with other individuals affect millions of persons. Especially health care professionals are required to wear masks for long periods of time. However, the quantitative effects of medical masks on cardiopulmonary exercise capacity have never been systematically reported.
Disposable surgical masks are intended to reduce transmissions from the wearer to the patient, hand-to-face contact, and facial contact with large droplets. EN149 FFP2 protective mask and NIOSH N95 facepiece respirators meet filtration requirements of small airborne particles, fit tightly to the wearer’s face made by China FFP2 mask Company, and have been suggested to be more efficacious than surgical masks in reducing exposure to viral infections. They are, therefore, widely employed by health care professionals for self-protection, especially during the COVid-19 pandemic. However, randomized trials didn’t find significant differences between en149 FFP2 protective mask and Niosh N95 and surgical masks in preventing influenza infections or respiratory disease.
Studies on cardiopulmonary capacity have been performed using respirator masks, e.g., full-facepiece masks, filtering air-purifying respirators (APR), air-supplied respirators, blower powered air-purifying respirators (PAPR), and self-contained breathing apparatus (SCBA). These respirators are better known as “gas masks” that are not used by health care professionals and are not suitable to be worn by the majority of the population. Data on cardiopulmonary capacity wearing medical masks are not available. Since surgical and FFP2 protective masks and N95 masks are the two most widely used types of medical face masks, they were included in this study protocol.
EN149 FFP2 mask
The en149 ffp2 face mask offers protection in various areas like the glass industry, foundry, construction, pharmaceutical industry, and agriculture. It effectively stops powdered chemicals. This mask also can function protection against influenza viruses like avian influenza or severe acute respiratory syndrome-related to the coronavirus (SARS), also as against the bacteria of plague and tuberculosis. it’s almost like the N95 mask.
the mask should be as on the brink of the face as possible; a metal tab makes it possible to regulate the mask to the bridge of the nose. A beard isn’t recommended and therefore the elastics should be shortened by a button for young children.
As protection against infectious diseases, it’s only effective together with frequent and effective hand washing. The mask shouldn’t be touched during use. The mask should get replaced when wet. It should be removed by taking it from the rear without touching the front of the mask then placing it into an appropriate closed container before washing hands again. to guard people the mask shouldn’t have an exhalation valve
In addition to health care professionals, information on cardiopulmonary effects of face masks in healthy adults could be important for different groups of individuals. Virus particles in respiratory droplets may be transmitted to a greater extent during different forms of physical exertion, many amateurs and professional sports or activities such as singing. Face masks have, therefore, been discussed as a means to engage in these activities for a wide range of individuals. Therefore, this randomized cross-over study aimed to provide a detailed quantification of the effect of surgical and EN149 FFP2 protective mask and N95 masks on pulmonary and cardiac capacity in healthy adults.
