A study on vocal breathing to improve activity blood oxygen saturation when wearing a mask

At present, because of the COVID-19 epidemic, wearing masks has become routine People work and live while wearing masks Masks isolate the virus but also hinder people's breathing Wearing masks for long-term activities will have negative effects, and the most direct effect is the decrease in oxygen content in the body These negative effects are common in people who engage in high oxygen consumption activities Such as workers and medical staff working on the front line They often suffer from shortness of breath, headaches, and fatigue when wearing masks for a long time This paper proposes three vocal breathing modes to solve decreased blood oxygen saturation when wearing a mask Furthermore, sitting, walking, running simulate people's life and work Namely office work, attendance, and sports This paper aims to study improving blood oxygen saturation of three vocal breathing patterns under different activity states A pulse oximeter measures the blood oxygen saturation The results showed that in the sitting state, the three vocal breathing modes had the same effect on improving blood oxygen When walking, the “U~” vocal breathing pattern is better The normal breathing mode and "Voo~" vocal breathing mode are recommended in the running state © 2021 Seventh Sense Research Group®
