On an Umm~ vocal breathing pattern to im-prove blood oxygen saturation when wearing a mask

초록

With the spread of COVID-19 around the world. Many governments will obligate and enforce mask-wearing. This caused a lot of dissatisfaction. This is mainly because wearing a mask can cause respiratory discomfort and hypoxia. This is considered harmful to health. However, the anti-epidemic effect of masks is remarkable, and there is no other better anti-epidemic plan. Wearing masks is still the mainstream. Therefore, reducing the side effects of masks has become particularly important. This article proposes a new solution. That is, “Umm~” speaks and breathes. This is an active-controlled breathing mode. It can increase respiratory efficiency, thereby increasing the oxygen content in the body. In experiments to evaluate the body's oxygen content, we use blood oxygen saturation as an indicator. Experimental results show that the normal breathing mode cannot meet the human body's blood oxygen demand under the condition of wearing a mask. The “Umm~” vocal breathing can significantly alleviate the decline in blood oxygen saturation. After using this method, blood oxygen saturation increased by approximately 2.5%. © 2021 Seventh Sense Research Group®
