On a long breathing method to improve blood oxygen saturation when wearing a mask

Abstract

With the spread of COVID-19 around the world. Wearing a mask has caused some controversy. The mask will increase breathing resistance and cause hypoxia. This is the reason that many people oppose wearing masks. However, the anti-epidemic effect of masks has been scientifically proven. To make more people accept wearing masks, this article proposes a new solution. Namely, the long breath mode. It does not require any changes to the mask's structure, only that we need to change the original breathing pattern. This article demon-strates that a new breathing program can increase air intake, activate lung function, and obtain more oxygen. We then tried to use blood oxygen saturation as an indicator of the human oxygen level to prove its effectiveness. A photoelectric pulse oximeter developed according to different light absorption principles in the blood is used to test blood oxygen saturation. Experimental results show that wearing a mask under high oxygen consumption can cause a period of hypoxia. It has been confirmed that the recommended long breathing method increases the oxygen saturation in the body's blood and relieves the lack of oxygen in the body. © 2020 Seventh Sense Research Group®.
