Pandemic significantly affects breathing (archived here). Accordingly, can For small children, the supply of fresh air is limited by covering their mouth and nose reduce up to 61 percent. For children the value is up to 32 and Adults up to 16 percent. The reason is that masks have the so-called dead space artificially expand in which there is no exchange of fresh air. Instead, exhaled air collects under the mask and is released again is inhaled. EVALUATION: The calculations in the graphic are misleading. On the one hand, create Everyday masks do not have a complete dead space. Since they are not airtight, The exhaled air mixes with fresh air from outside. For the Others, the graphic ignores the fact that the body breathes accordingly adjusts if it does not receive enough fresh, oxygen-rich air. The Wearing a mouth and nose cover is essential for healthy people harmless and does not lead to oxygen deficiency. FACTS: The air under the mask only makes up a small portion of the air, which you breathe in as a whole. A healthy adult has one at rest Tidal volume that ranges from just under 500 milliliters to just under a liter is enough, explains Michael Achenbach, doctor and spokesman for the professional association of pediatricians and adolescent doctors (BVKJ). This happens easily under load can be increased by several liters. The air under the mask, on the other hand, is significantly less than 50 milliliters. The graphic here assumes an extended dead space of 80 milliliters adults and children - but according to the doctor, this value is too high set high. In addition, this is not just a dead space volume. This will make it space in the respiratory tract in which there is no exchange with fresh, there is oxygen-rich air. Because the air mixes under an everyday mask with the air from outside. With such masks you breathe through the material, But air also comes in from the sides. Children could also wear such masks. It's been a long time in the hospital usual. “For children in a cancer ward, for example, this is quite common they wear a mask. “That has never been a cause for concern,” says Achenbach. From completely closed masks such as dust masks from the hardware store The doctor advises against it in children. The Internet article also mentions the danger of a lack of oxygen indicated. So it is said that children do not have such a deficiency for long tolerated. According to the expert, such a lack of oxygen is threatened by a corona virus. But not an everyday mask. On the one hand, even the exhaled air always contains still around 17 percent oxygen, while in fresh air it is just under 21 percent are. The graphic also ignores the fact that the body reacts accordingly if it does not receive enough oxygen-rich air. «That's what it's for Receptors in the brain, you simply breathe deeper and faster,” explains Achenbach. “Think of Reinhold Messner,” the pediatrician gives an example. It is him finally managed to climb Mount Everest without additional to use oxygen. This shows what compensation benefits the body is capable. \--- Left: Post on Facebook: (archived: Mask recommendation from the German Society for Pediatric and Adolescent Medicine (DGKJ): (archived: \--- Contact the dpa fact check team: faktencheck@dpa.com powered by dpa-newslab | Imprint | Privacy | About:
