Blood oxygen knowledge

Blood oxygen is a very important life parameter for the human body. Performing mental work in a closed environment for a long time will lead to a decrease in blood oxygen in the human body.
When blood oxygen is too low, people will feel dizzy, have difficulty breathing, and have chest pain.
At this time, you must go to an open space or open a window for ventilation, and then take a big breath to increase the intake of air. If necessary, you need to receive oxygen therapy or seek medical treatment.
You can also use the COLMI watch to check your real-time blood oxygen through the blood oxygen detection function above to avoid the discomfort caused by low blood oxygen.
