If oxygen concentrations fall between 91% and 95%, it is a cause for concern. This signifies an underlying medical problem and it is advised that if you have a reading in this range, that you contact your healthcare provider.
Low blood oxygen rateis medically defined as percentages that fall below 90% oxygen saturation. In short, readings at this level indicate a medical emergency. You should call 911 immediately if blood oxygen saturation falls this low
If a patient’s oxygen saturation level falls to 85% or below, the brain is being adversely affected due to lack of oxygen. Symptoms include vision changes or loss of vision and total blackout.
If blood oxygen saturation levels fall to around 67%, Cyanosis will set it. The lack of oxygen being transported by your blood cells, causes a blue tinge to develop on your skin. Your mouth, lips, and beneath your fingernail matrix will be affected first, followed by the spread occurring over the rest of your body.
Understanding blood oxygen saturation levels is very important when using a pulse oximeter at home. If you take a reading lower than 95% you now know that action does need to be taken.
People over 70 years of age may have oxygen levels closer to 95%, which can be normal for that age group, while normal SpO2 rates for infants and children are usually 97% and higher. Low levels of oxygen in the body’s tissues are called hypoxia. Low levels of oxygen in the blood are called hypoxemia.
