Brain injury: If the brain does not get enough oxygen, a lot of problems can occur, such as dizziness, memory loss, seizures, and unconsciousness. If the brain is deprived of oxygen for a prolonged period of time, permanent damage can occur and is called anoxic (or hypoxic) brain injury. Someone with this condition is usually very sick and may be in a coma.

Oximeter: Buy yourself a pulse oximeter, you can find them online and they are not too expensive, $20-30. If your oxygen saturation is in the lower 90-es or falls below 90%, see a doctor.

They pass out: Generally, if a person isnt getting enough oxygen to the brain, he or she will pass out. This is the body's way of protecting the brain by increasing blood flow in the lying position. It is unlikely that minor symptoms are related to lack of oxygen.
