Blood oxygen value is blood oxygen saturation, and the maximum solubility of oxygen in blood is the concentration of blood oxygen. It is generally believed that the normal blood oxygen value should not be lower than 94%, and the oxygen supply below 94% is insufficient, which may be due to the increase or obstruction of upper respiratory secretions during sleep, which leads to the decrease of blood oxygen saturation and the increase of carbon dioxide concentration.
So it's 98 when I'm awake, sometimes it drops to 93 when I'm asleep, but it returns to 98 immediately after I wake up. This phenomenon is normal if there is no pathological state.

Precautions:
1. Please clean the surface of the finger pressure oximeter before use.
2. Cleaning the oximeter can use the most commonly used cleaning solution and non-corrosive cleaning agent in the hospital.
Many cleaning agents must be diluted before use. Please follow the instructions of the cleaner manufacturer.
4. Avoid using alcohol, amino or acetone-based cleaners.
