Fluctuating Oxygen Levels
Sleep apnea increases your risk for lowered oxygen levels in the blood. Normal blood oxygen levels in humans are considered to be from 95-100%. If your saturation level falls below 92%, it may result in your cells being starved of oxygen. If your level is below 90%, you are considered to be in hypoxemia, an abnormally low concentration of oxygen in the blood.
Many people living with sleep apnea may suffer from hypoxia, a similar condition in which the tissues of the body are deprived of adequate oxygen. Prolonged hypoxia can cause organ damage, with the brain, heart and liver being particularly susceptible.
