What do my pulse oximetry results mean?

ANSWER

A blood oxygen level lower than 89% means you may not have enough oxygen in your blood to meet your body's needs. This could be because there's a problem with your heart or lungs. If your levels are low, you may need to breathe in extra oxygen through a tube.
