They argue the masks caused more Carbon dioxide and less oxygen in the blood. This will happen with re-breathing based on your own used breathing air. An Austrian practical man Doctor also claims masks promote lung disease ( EVALUATION: It is true that people with certain lung diseases... Wearing masks is not recommended. But there is no evidence that masks promote lung disease or that they are dangerous or ineffective. FACTS: A Facebook posting refers to a general practitioner from Styria under the heading \"Medical Information Covid-19-LV\" after the introductory sentence \"If you wear a mask, From a medical perspective, the following happens:\" five claims made. In point 1 it is claimed that inhaling the exhaled air under the Face masks enrich the blood with carbon dioxide and nitric oxide. In point 2 it says: \"You absorb less oxygen than usual.\" Oxygen is but important for all vital functions of the body. It is true that in a 2004 submission - and in social networks reproduced distorted - doctoral thesis at the Technical University of Munich after use A slightly increased CO2 content in the blood was found from surgical masks. One An increase in respiratory rate or a drop in oxygen saturation was observed but not proven. There was also no significant heartbeat Increase or decrease ( The author of the Doctoral thesis, Ulrike Butz, told the German Press Agency on May 4, 2020: \"You cannot derive any health impairments from work. That would be dubious." According to the German Respiratory League, they have professional masks (FFP2, FFP3) a “significant breathing resistance”. So you need more strength for breathing. This can cause "significant shortness of breath" in sick patients. lead. The proportion of carbon dioxide in the blood can increase. \"In practice However, those affected will take off the mask in good time.\" Threatening Increases in CO2 levels in the blood due to masks are "unlikely", says a paper from the respiratory league. On the other hand, with a simple one surgical mask or a self-made mouth and nose cover An increase in carbon dioxide is unlikely because these masks are not completely be tight. In patients with chronic respiratory failure, however, the Carbon dioxide content and the work of breathing increase, so that the covering of the mouth and nose as unpleasant or threatening and subjectively as shortness of breath is perceived" ( According to the, only people with serious previous illnesses should Experts may recommend not wearing a face mask. At the Recommendations to wear mouth and nose protection must be taken into account, that there are people who, for medical or other valid reasons "We cannot wear a mouth and nose covering," it said in a statement Robert Koch Institute ( On March 9, the European Lung Foundation ELF said: "Already Existing chronic respiratory diseases do not require wearing a mask recommended as this can make breathing difficult" ( Also the German Society for Pneumology and Respiratory Medicine (DGP) in Berlin recommends caution in patients with heart and lung disease as well Shortness of breath when it comes to wearing the mouth and nose covering. Be the best a blood gas analysis to determine tolerance. Depending on what is used Material may require greater breathing effort when wearing the mask ( Point 3 of the post "Medical Information Covid-19-LV" states: "Your Lungs are no longer ventilated as they should. (This encourages lung diseases)\". Regarding this claim, Dr. Önder Yildirim, director of the Institute for Lung biology at the Helmholtz Center Munich, May 18th. 2020 of the Germans Press agency: "That's not true. There are no studies about that a mask would cause lung disease." When using the Professional masks are more effective for patients with respiratory diseases \"Fatigue\" when breathing is to be expected. \"But tiredness doesn't mean that a disease is promoted.\" If the amount of carbon dioxide is short-term If you take off the mask, it will go away again within seconds be better." "Wearing masks will not cause lung disease," says Yildirim on the masks that are now available in shops or public places, for example Means of transport are mandatory in Germany. Rather, it is the opposite the case: "We recommend that people use the masks to protect themselves against "To protect against Covid-19, which is a lung disease." Point 4 of the Facebook posting states that if the mask is longer than one If you wear it for half an hour, it will become “germinated”. Plus, that's what they say in point 5, the mask cannot hold back viruses (this is in the original post Word viruses in quotation marks). This objection is also dismissed by Dr. Yildirim does not apply. \"If we enter or "When we breathe out, we have certain bacteria in our airways," he says. These are “not necessarily pathogenic” (disease-causing). Because the mask To absorb these bacteria, masks should either only be used once or clean carefully. That's why you're allowed to wear another person's mask do not use. The bacteria in the mask are no reason to worry: "In principle, these are bacteria that we already have in our lungs or mouth have.\" The researcher says that the mask cannot hold back viruses from the Helmholtz Center: \"That's not true either.\" Normal Cloth masks can, for the most part, prevent the droplets from escaping "Go out your mouth." This means that the viruses automatically get into the masks stay: \"The mask doesn't protect you, but it protects other people.\" Also in the mentioned paper from the German Society for Pneumology and Respiratory medicine (DGP) "on the effect of nose-mouth masks on the patient's and third-party protection for airborne infections\" will be the significant protective effect for the people who encounter the mask wearer described in detail. ``` --- ``` Left: Facebook posting: (archived: Dissertation surgical masks: (archived: Communication from the Lung Foundation: overview/current/article/coronavirus-infos-for-people-with- lung diseases//index.html (archived: Announcement from the Society for Pulmonology: Mund-Masken.pdf (archived: Communication from the Robert Koch Institute: (archived: Communication from the respiratory league: zu-covid-19/general-recommendations.html (archived: ``` --- ``` Contact the dpa fact check team: faktencheck@dpa.com © dpa German Press Agency GmbH.
